Abstract interface for data compression classes.
vtkDataCompressor provides a universal interface for data compression. Subclasses provide one compression method and one decompression method. The public interface to all compressors remains the same, and is defined by this class.

Uncompress the given data. A vtkUnsignedCharArray containing the compressed data is returned with a reference count of 1. The size of the uncompressed data must be known by the caller. It should be transmitted from the compressor by a means outside of this class.

Return 1 if this class type is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.

Methods invoked by print to print information about the object including superclasses. Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.

Get the maximum space that may be needed to store data of the given uncompressed size after compression. This is the minimum size of the output buffer that can be passed to the four-argument Compress method.
Implemented in vtkZLibDataCompressor.
unsigned long vtkDataCompressor::Compress | ( | const unsigned char * | uncompressedData, |
unsigned long | uncompressedSize, | ||
unsigned char * | compressedData, | ||
unsigned long | compressionSpace | ||
) |
Compress the given input data buffer into the given output buffer. The size of the output buffer must be at least as large as the value given by GetMaximumCompressionSpace for the given input size.
unsigned long vtkDataCompressor::Uncompress | ( | const unsigned char * | compressedData, |
unsigned long | compressedSize, | ||
unsigned char * | uncompressedData, | ||
unsigned long | uncompressedSize | ||
) |
Uncompress the given input data into the given output buffer. The size of the uncompressed data must be known by the caller. It should be transmitted from the compressor by a means outside of this class.
vtkUnsignedCharArray* vtkDataCompressor::Compress | ( | const unsigned char * | uncompressedData, |
unsigned long | uncompressedSize | ||
) |
Compress the given data. A vtkUnsignedCharArray containing the compressed data is returned with a reference count of 1.
vtkUnsignedCharArray* vtkDataCompressor::Uncompress | ( | const unsigned char * | compressedData, |
unsigned long | compressedSize, | ||
unsigned long | uncompressedSize | ||
) |
Uncompress the given data. A vtkUnsignedCharArray containing the compressed data is returned with a reference count of 1. The size of the uncompressed data must be known by the caller. It should be transmitted from the compressor by a means outside of this class.
