Member Function Documentation

◆ Compress()

bool ON_CompressedBuffer::Compress	(	size_t	sizeof__inbuffer,
		const void *	inbuffer,
		int	sizeof_element
	)

Compress inbuffer.

Parameters

sizeof__inbuffer	[in] Number of bytes in inbuffer.
inbuffer	[in] Uncompressed information.
sizeof_element	[out] This parameter only matters if the buffer will be compressed, and decompressed on CPUs with different endianness. If this is the case, then the types in the buffer need to have the same size (2,4, or 8).

Returns: True if inbuffer is successfully compressed.

◆ CompressionEnd()

bool ON_CompressedBuffer::CompressionEnd ( struct ON_CompressedBufferHelper * ) const

◆ CompressionInit()

bool ON_CompressedBuffer::CompressionInit ( struct ON_CompressedBufferHelper * ) const

◆ DeflateHelper()

size_t ON_CompressedBuffer::DeflateHelper	(	struct ON_CompressedBufferHelper *	,
		size_t	sizeof___inbuffer,
		const void *	in___buffer
	)

◆ Destroy()

void ON_CompressedBuffer::Destroy ( )

Destroy the current informtion in the ON_CompressedBuffer so the class can be reused.

◆ InflateHelper()

bool ON_CompressedBuffer::InflateHelper	(	struct ON_CompressedBufferHelper *	,
		size_t	sizeof___outbuffer,
		void *	out___buffer
	)		const

◆ operator=()

ON_CompressedBuffer& ON_CompressedBuffer::operator= ( const ON_CompressedBuffer & src )

◆ Read()

bool ON_CompressedBuffer::Read ( ON_BinaryArchive & binary_archive )

◆ SizeOfUncompressedBuffer()

size_t ON_CompressedBuffer::SizeOfUncompressedBuffer ( ) const

Returns: Number of bytes in the uncompressed information.

◆ Uncompress()

bool ON_CompressedBuffer::Uncompress	(	void *	outbuffer,
		int *	bFailedCRC
	)		const

Uncompress the contents of this ON_CompressedBuffer.

Parameters

outbuffer	[in/out] This buffer must have at least SizeOfUncompressedBuffer() bytes. If the function returns true, then the uncopressed information is stored in this buffer.
bFailedCRC	[out] If not null, then this boolean is set to true if the CRC of the uncompressed information has changed.

Returns: True if uncompressed information is returned in outbuffer.

◆ Write()

bool ON_CompressedBuffer::Write ( ON_BinaryArchive & binary_archive ) const

◆ WriteChar()

bool ON_CompressedBuffer::WriteChar	(	size_t	count,
		const void *	buffer
	)
