Object Creation
CkCompression obj = new CkCompression();
Properties
Algorithm
Specifies the compression algorithm to use. Supported values are
deflate, zlib, bzip2, and lzw.
The zlib option is the deflate algorithm with a zlib header.
Note: ppmd is deprecated and should not be used.
It was only available on 32-bit systems and specifically used the J variant.
New applications should use one of the supported algorithms listed above.
Charset
Specifies the character encoding used when converting text to bytes before compression, and bytes back to text after decompression.
The current default is the computer’s ANSI charset, such as Windows-1252 on many
Western Windows systems. However, most modern applications should explicitly set
this property to utf-8.
Recommendation: Set Charset = "utf-8" unless you
specifically need compatibility with another encoding.
DebugLogFilePath
String debugLogFilePath();
void put_DebugLogFilePath(String 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.
DeflateLevel
void put_DeflateLevel(int newVal);
Sets the compression level used by the deflate and zlib
algorithms.
0means no compression.9means maximum compression.- The default value is
6.
Higher values may produce smaller output but can require more processing time.
topEncodingMode
Specifies the text encoding used by methods whose names end in ENC,
such as CompressBytesENC and DecompressStringENC.
Compression methods ending in ENC return compressed binary data as
an encoded string. Decompression methods ending in ENC expect the
input string to use this same encoding.
Valid values include:
base64hexurlquoted-printable
FirstChunk
void put_FirstChunk(boolean newVal);
Indicates that the next chunk-aware compression or decompression call is the first chunk in a sequence.
The default value is true
When both FirstChunk and LastChunk are
true
HeartbeatMs
void put_HeartbeatMs(int newVal);
Specifies the interval, in milliseconds, between AbortCheck event
callbacks.
This allows an application to periodically check whether a long-running operation should be aborted.
The default value is 0, which disables AbortCheck
callbacks.
LastChunk
void put_LastChunk(boolean newVal);
Indicates that the next chunk-aware compression or decompression call is the final chunk in a sequence.
The default value is true
When both FirstChunk and LastChunk are
true
LastErrorHtml
Provides HTML-formatted information about the last called method or property. If a method call fails or behaves unexpectedly, check this property for details. Note that information is available regardless of the method call's success.
topLastErrorText
Provides plain text information about the last called method or property. If a method call fails or behaves unexpectedly, check this property for details. Note that information is available regardless of the method call's success.
LastErrorXml
Provides XML-formatted information about the last called method or property. If a method call fails or behaves unexpectedly, check this property for details. Note that information is available regardless of the method call's success.
topLastMethodSuccess
void put_LastMethodSuccess(boolean 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.
UncommonOptions
String uncommonOptions();
void put_UncommonOptions(String newVal);
Provides a way to enable specialized or uncommon behavior. This property normally remains empty.
It may be set to a comma-separated list of keywords.
Supported option:
-
Crypt2CompressHdr— Duplicates the compression/decompression header behavior used by the deprecated and removed Crypt2 compression functions.
VerboseLogging
void put_VerboseLogging(boolean 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.

Events
Chilkat supports event callbacks in Java (including Android) starting in version 9.5.0.52. To implement an event callback, your application would define and implement a class that derives 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:
// Install an event callback handler to get progress events. MyBaseProgress compressionProgress = new MyBaseProgress(); http.put_EventCallbackObject(compressionProgress);
MyBaseProgress example:
import com.chilkatsoft.CkBaseProgress;
import com.chilkatsoft.CkTask;
public class MyBaseProgress extends CkBaseProgress
{
public boolean AbortCheck()
{
System.out.println("AbortCheck");
// Return true to abort, false to allow the method to continue.
return false;
}
// pctDone is a value from 0 to 100
// (it is actually value from 0 to the PercentDoneScale property setting)
public boolean PercentDone(int pctDone)
{
System.out.println(pctDone);
// Return true to abort, false to allow the method to continue.
// Note: A PercentDone event is the equivalent of an AbortCheck.
// When PercentDone events are frequently firing, AbortCheck events are suppressed.
// AbortCheck events will fire when the time between PercentDone events is longer
// than the HeartbeatMs property setting.
return false;
}
public void ProgressInfo(String name, String value)
{
System.out.println(name + ": " + value);
}
public void TaskCompleted(CkTask task)
{
System.out.println("task completed!");
}
}
AbortCheck
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. Return true to abort; return false to continue (not abort)
PercentDone
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.
Return true to abort; return false to continue (not abort)
ProgressInfo
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.
TaskCompleted
Called from the background thread when an asynchronous task completes.
