Detailed Description

Push interface.

Low-level push interface for in-memory IO.

Version

1.0

Examples

testsuite/http.cpp.

Member Function Documentation

flush()

virtual void PushInterface::flush ( )

virtual

Forces any buffered bytes to be written out. This method is ignored by unbuffered streams.

Reimplemented in Deflater, BZip2Deflater, and ZLibDeflater.

push()

virtual MemorySize PushInterface::push ( const uint8 *  buffer, MemorySize  size  )

pure virtual

Pushes the specified number of bytes onto the stream.

Parameters

buffer	The buffer containing the bytes to be pushed.
size	The number of bytes to be pushed.

Returns

The number of bytes pushed.

Implemented in CRC32, Adler32, SHA256, SHA512, SHA384, SHA1, BZip2Deflater, ZLibDeflater, BZip2Inflater, ZLibInflater, MD5Sum, and LocalConnection.

Examples

testsuite/http.cpp.

pushBegin()

virtual bool PushInterface::pushBegin ( uint64  totalSize )

virtual

Begins the pushes.

Parameters

totalSize

The total number of bytes to be pushed.

Examples

testsuite/http.cpp.

pushEnd()

virtual void PushInterface::pushEnd ( )

virtual

This method should be invoked when the end has been reached. This method may be ignored by some implementations.

Reimplemented in SHA256, SHA512, SHA384, SHA1, CRC32, BZip2Deflater, ZLibDeflater, BZip2Inflater, ZLibInflater, MD5Sum, and LocalConnection.

Examples

testsuite/digest.cpp, and testsuite/http.cpp.
