Constructor & Destructor Documentation

GZIPCompressorOutputStream::GZIPCompressorOutputStream ( OutputStream destStream,
int  compressionLevel = 0,
bool  deleteDestStreamWhenDestroyed = false,
bool  noWrap = false 
)

Creates a compression stream.

Parameters:
destStream the stream into which the compressed data should be written
compressionLevel how much to compress the data, between 1 and 9, where 1 is the fastest/lowest compression, and 9 is the slowest/highest compression. Any value outside this range indicates that a default compression level should be used.
deleteDestStreamWhenDestroyed whether or not to delete the destStream object when this stream is destroyed
noWrap this is used internally by the ZipFile class and should be ignored by user applications
GZIPCompressorOutputStream::~GZIPCompressorOutputStream (  ) 

Destructor.


Member Function Documentation

void GZIPCompressorOutputStream::flush (  )  [virtual]

If the stream is using a buffer, this will ensure it gets written out to the destination.

Implements OutputStream.

int64 GZIPCompressorOutputStream::getPosition (  )  [virtual]

Returns the stream's current position.

See also:
setPosition

Implements OutputStream.

bool GZIPCompressorOutputStream::setPosition ( int64  newPosition  )  [virtual]

Tries to move the stream's output position.

Not all streams will be able to seek to a new position - this will return false if it fails to work.

See also:
getPosition

Implements OutputStream.

bool GZIPCompressorOutputStream::write ( const void *  dataToWrite,
int  howManyBytes 
) [virtual]

Writes a block of data to the stream.

When creating a subclass of OutputStream, this is the only write method that needs to be overloaded - the base class has methods for writing other types of data which use this to do the work.

Returns:
false if the write operation fails for some reason

Implements OutputStream.
