◆ Compress()

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

Description: 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.

◆ CompressionInit()

◆ Destroy()

void ON_CompressedBuffer::Destroy ( )

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

◆ InflateHelper()

bool ON_CompressedBuffer::InflateHelper ( struct ON_CompressedBufferHelper *  ,

void *  out___buffer

◆ operator=()

◆ 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

Description: 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.
