CkZipEntry

Current Version: 11.4.0
Requires Chilkat Bundle License

The Chilkat.ZipEntry class represents a single entry contained within a Chilkat.Zip object.

For a more complete introduction and conceptual overview, see:

ZipEntry Overview

A ZipEntry may represent:

  • A file already contained within an opened ZIP archive
  • A referenced filesystem file that has not yet been compressed
  • An in-memory data entry containing text or binary data
  • A directory entry

ZipEntry objects provide access to ZIP entry metadata such as:

  • Filename and stored ZIP path
  • Compressed and uncompressed sizes
  • Compression method and compression level
  • Encryption information
  • Last-modified timestamps
  • CRC values and entry attributes

ZipEntry objects can also be used to:

  • Extract individual entries
  • Inflate entry contents directly into memory
  • Replace or append entry data
  • Iterate through ZIP archive entries
  • Access compressed entry data

A ZipEntry object is typically obtained from a Chilkat.Zip object using methods such as EntryAt, EntryOf, EntryMatching, or FirstEntry.

The EntryType property indicates the current state of the entry, such as whether it is a mapped entry from an existing ZIP, a referenced filesystem file awaiting compression, or an in-memory data entry.

Object Creation

Properties

Comment
void get_Comment(CkString &str);
const char *comment(void);
void put_Comment(const char *newVal);

Gets or sets the comment stored in the ZIP archive for this entry.

top
CompressedLength
unsigned long get_CompressedLength(void);

The compressed size of this entry, in bytes.

For mapped entries (entries already contained within an opened ZIP archive), this property contains the actual compressed size stored within the ZIP.

For file entries or data entries that have not yet been written to a ZIP archive, compression has not yet occurred. In these cases, this property contains:

  • The current uncompressed data size for data entries.
  • The cached filesystem file size for referenced file entries.

After the ZIP archive is written, the entries become mapped entries, and this property then reflects the actual compressed size stored in the ZIP archive.

top
CompressedLength64
__int64 get_CompressedLength64(void);

The compressed size of this entry, in bytes, as a 64-bit integer.

For mapped entries (entries already contained within an opened ZIP archive), this property contains the actual compressed size stored within the ZIP.

For file entries or data entries that have not yet been written to a ZIP archive, compression has not yet occurred. In these cases, this property contains:

  • The current uncompressed data size for data entries.
  • The cached filesystem file size for referenced file entries.

After the ZIP archive is written, the entries become mapped entries, and this property then reflects the actual compressed size stored in the ZIP archive.

Use this property when sizes may exceed the range of a 32-bit integer.

top
CompressedLengthStr
void get_CompressedLengthStr(CkString &str);
const char *compressedLengthStr(void);

The compressed size of this entry as a decimal string.

For mapped entries (entries already contained within an opened ZIP archive), this property contains the actual compressed size stored within the ZIP.

For file entries or data entries that have not yet been written to a ZIP archive, compression has not yet occurred. In these cases, this property contains:

  • The current uncompressed data size for data entries.
  • The cached filesystem file size for referenced file entries.

After the ZIP archive is written, the entries become mapped entries, and this property then reflects the actual compressed size stored in the ZIP archive.

This property is useful when sizes may exceed the range of a 32-bit integer.

top
CompressionLevel
int get_CompressionLevel(void);
void put_CompressionLevel(int newVal);

Gets or sets the compression level for this entry.

A value of 0 means no compression, and a value of 9 means maximum compression.

The default value is 6.

top
CompressionMethod
int get_CompressionMethod(void);
void put_CompressionMethod(int newVal);

Gets or sets the compression method used for this entry.

  • 0 means no compression.
  • 8 means Deflate compression.

Deflate is the standard compression algorithm used by common ZIP utilities such as WinZip.

top
Crc
int get_Crc(void);

The CRC value for this ZIP entry.

For AES-encrypted entries, the CRC value is 0.

top
DebugLogFilePath
void get_DebugLogFilePath(CkString &str);
const char *debugLogFilePath(void);
void put_DebugLogFilePath(const char *newVal);

If set to a file path, this property logs the LastErrorText of each Chilkat method or property call to the specified file. This logging helps identify the context and history of Chilkat calls leading up to any crash or hang, aiding in debugging.

Enabling the VerboseLogging property provides more detailed information. This property is mainly used for debugging rare instances where a Chilkat method call causes a hang or crash, which should generally not happen.

Possible causes of hangs include:

  • A timeout property set to 0, indicating an infinite timeout.
  • A hang occurring within an event callback in the application code.
  • An internal bug in the Chilkat code causing the hang.

More Information and Examples
Example showing how to use DebugLogFilePath.
top
EncryptionKeyLen
int get_EncryptionKeyLen(void);
Introduced in version 9.5.0.69

The AES encryption key length for this entry.

If this entry is AES encrypted, the value is 128, 192, or 256.

If this entry is not AES encrypted, the value is 0.

top
EntryID
int get_EntryID(void);

A unique identifier assigned to this entry while the ZIP object is instantiated in memory.

This ID can be used to retrieve the same entry later with Zip.EntryById.

top
EntryType
int get_EntryType(void);

Indicates the origin and current state of this ZIP entry.

  • 0 — Mapped Entry: an entry that already exists in an open ZIP file.
  • 1 — File Entry: a file in the local filesystem that has been referenced, but not yet read or compressed.
  • 2 — Data Entry: an entry containing uncompressed data already held in memory.
  • 3 — Null Entry: an entry that no longer exists in the ZIP archive.
  • 4 — New Directory Entry: a directory entry added to the ZIP object.

When the ZIP archive is written by calling WriteZip or WriteToMemory, entries are transformed into mapped entries. In other words, after writing, they point to compressed data contained in the newly created or rewritten ZIP archive.

top
FileName
void get_FileName(CkString &str);
const char *fileName(void);
void put_FileName(const char *newVal);

Gets or sets the filename, including any relative path, stored for this entry inside the ZIP archive.

Changing this property changes the path/name that will appear in the ZIP archive. It does not rename a source file in the local filesystem.

top
LastMethodSuccess
bool get_LastMethodSuccess(void);
void put_LastMethodSuccess(bool newVal);

Indicates the success or failure of the most recent method call: true means success, false means failure. This property remains unchanged by property setters or getters. This method is present to address challenges in checking for null or Nothing returns in certain programming languages. Note: This property does not apply to methods that return integer values or to boolean-returning methods where the boolean does not indicate success or failure.

top
TextFlag
bool get_TextFlag(void);
void put_TextFlag(bool newVal);

Gets or sets the text flag in the internal file attributes for this ZIP entry.

This flag indicates whether the entry contents should be considered text rather than binary data.

The flag is informational and does not need to be accurate for normal ZIP processing. It is provided for compatibility with applications that may be sensitive to this attribute.

top
UncompressedLength
unsigned long get_UncompressedLength(void);

top
VerboseLogging
bool get_VerboseLogging(void);
void put_VerboseLogging(bool newVal);

If set to true, then the contents of LastErrorText (or LastErrorXml, or LastErrorHtml) may contain more verbose information. The default value is false. Verbose logging should only be used for debugging. The potentially large quantity of logged information may adversely affect peformance.

top
Version
void get_Version(CkString &str);
const char *version(void);

Version of the component/library, such as "10.1.0"

Methods

AppendString
bool AppendString(const char *strContent, const char *charset);

Appends text data to this ZIP entry's file contents.

The text is converted to bytes using the character encoding specified by charset, such as utf-8, utf-16, or ansi.

If this entry is already a Data Entry (EntryType = 2), then the encoded bytes are appended directly to the existing uncompressed in-memory data.

If this entry is not already a Data Entry, then the entry is first converted into a Data Entry before the new text data is appended.

  • If the entry is a mapped entry (EntryType = 0), the compressed ZIP entry data is first inflated into memory. The new text data is then appended, and the entry becomes a Data Entry containing the combined uncompressed data.
  • If the entry is a file entry (EntryType = 1), the referenced filesystem file is first loaded into memory. The new text data is then appended, and the entry becomes a Data Entry containing the combined data.

After this method is called, the entry contents exist entirely as uncompressed in-memory data associated with the ZipEntry object.

Returns true for success, false for failure.

More Information and Examples

Note: The application is responsible for deleting (via the C++ delete operator) the object returned by this method.

Returns NULL on failure

top
CopyToBase64
bool CopyToBase64(CkString &outStr);
const char *copyToBase64(void);

Returns the compressed data for this ZIP entry as a Base64-encoded string.

This method can only be used when the entry already contains compressed data, meaning the entry is a mapped entry.

This is possible for entries from a ZIP archive that has already been opened, or after writing a ZIP archive while it remains open.

Returns true for success, false for failure.

This method can only be used when the entry already contains compressed data, meaning the entry is a mapped entry.

This is possible for entries from a ZIP archive that has already been opened, or after writing a ZIP archive while it remains open.

Returns true for success, false for failure.

top
Extract
bool Extract(const char *dirPath);

Extracts this ZIP entry beneath the specified base directory.

The entry is extracted according to the relative path stored in the ZIP archive.

For example, if the entry filename is docs/readme.txt and dirPath is c:/temp/output, the file is extracted to c:/temp/output/docs/readme.txt.

Use ExtractInto instead if the file should be extracted directly into a specific directory regardless of the path stored in the ZIP archive.

Returns true for success, false for failure.

Events

To implement an event callback, your application would define and implement a class that inherits from CkBaseProgress. Your application can implement methods to override some or all of the default/empty method implementations of the CkBaseProgress base class.

For example:

  CkZipEntry zipentry;

  MyZipEntryProgress callbackObj;

  zipentry.put_EventCallbackObject(&callbackObj);

MyZipEntryProgress example:

#include "CkBaseProgress.h"

class MyZipEntryProgress : public CkBaseProgress {

  public:
    MyZipEntryProgress();
    virtual ~MyZipEntryProgress();

    void AbortCheck(bool  *abort);

    void PercentDone(int pctDone, bool  *abort);

    void ProgressInfo(const char *name, const char *value);

    void TaskCompleted(CkTask &task);

};
AbortCheck
void AbortCheck(bool *abort);

Enables a method call to be aborted by triggering the AbortCheck event at intervals defined by the HeartbeatMs property. If HeartbeatMs is set to its default value of 0, no events will occur. For instance, set HeartbeatMs to 200 to trigger 5 AbortCheck events per second.

More Information and Examples
Chilkat Event Callback Examples
top
PercentDone
void PercentDone(int pctDone, bool *abort);

This provides the percentage completion for any method involving network communications or time-consuming processing, assuming the progress can be measured as a percentage. This event is triggered only when it's possible and logical to express the operation's progress as a percentage. The pctDone argument will range from 1 to 100. For methods that finish quickly, the number of PercentDone callbacks may vary, but the final callback will have pctDone equal to 100. For longer operations, callbacks will not exceed one per percentage point (e.g., 1, 2, 3, ..., 98, 99, 100).

The PercentDone callback also acts as an AbortCheck event. For fast methods where PercentDone fires, an AbortCheck event may not trigger since the PercentDone callback already provides an opportunity to abort. For longer operations, where time between PercentDone callbacks is extended, AbortCheck callbacks enable more responsive operation termination.

To abort the operation, set the abort output argument to true. This will cause the method to terminate and return a failure status or corresponding failure value.

top
ProgressInfo
void ProgressInfo(const char *name, const char *value);

This event callback provides tag name/value pairs that detail what occurs during a method call. To discover existing tag names, create code to handle the event, emit the pairs, and review them. Most tag names are self-explanatory.

Deprecated

AppendData Deprecated
bool AppendData(CkByteData &inData);

Appends binary data to this ZIP entry's file contents.

If this entry is already a Data Entry (EntryType = 2), then the bytes in inData are appended directly to the existing uncompressed in-memory data.

If this entry is not already a Data Entry, then the entry is first converted into a Data Entry before the new data is appended.

  • If the entry is a mapped entry (EntryType = 0), the compressed ZIP entry data is first inflated into memory. The new data is then appended, and the entry becomes a Data Entry containing the combined uncompressed data.
  • If the entry is a file entry (EntryType = 1), the referenced filesystem file is first loaded into memory. The new data is then appended, and the entry becomes a Data Entry containing the combined data.

After this method is called, the entry contents exist entirely as uncompressed in-memory data associated with the ZipEntry object.

Returns true for success, false for failure.
