Return 1 if this class 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.

Reimplemented from vtkDataCompressor.

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.

Reimplemented from vtkDataCompressor.

◆ New()

◆ GetMaximumCompressionSpace()

size_t vtkLZMADataCompressor::GetMaximumCompressionSpace ( size_t  size)
overridevirtual

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.

Implements vtkDataCompressor.

◆ SetCompressionLevel()

void vtkLZMADataCompressor::SetCompressionLevel ( int  compressionLevel)

Get/Set the compression level.
