Member Enumeration Documentation

enum CCompressionStreamProcessor::EDeleteProcessor

If to delete the used compression processor in the destructor. Enumerator: eDelete  Do delete processor object. eNoDelete  Do not delete processor object. Definition at line 175 of file stream.hpp.

enum CCompressionStreamProcessor::EState

Stream processor state. Enumerator: eActive  Processor ready to read/write. eFinalize  Finalize() already done, but End() not yet. eDone  End() done, processor cannot process data. Definition at line 181 of file stream.hpp.
