Detailed Description

Used as a wrapper for writing out original saves using the console, since it also does reads from the stream whilst open

Member Function Documentation

pos()

int64 Bagel::SaveReadWriteStream::pos ( ) const

inlineoverridevirtual

Obtain the current value of the stream position indicator.

Returns

The current position indicator, or -1 if an error occurred.

Reimplemented from Common::MemoryWriteStreamDynamic.

seek()

bool Bagel::SaveReadWriteStream::seek ( int64  offset, int  whence = SEEK_SET  )

inlineoverridevirtual

Set the stream position indicator for the stream.

The new position, measured in bytes, is obtained by adding offset bytes to the position specified by whence. If whence is set to SEEK_SET, SEEK_CUR, or SEEK_END, the offset is relative to the start of the file, the current position indicator, or end-of-stream, respectively. A successful call to the seek() method clears the end-of-stream indicator for the stream.

Note

The semantics of any implementation of this method is supposed to match that of ISO C fseek().

Parameters

offset	The relative offset in bytes.
whence	The seek reference: SEEK_SET, SEEK_CUR, or SEEK_END.

Returns

True on success, false in case of a failure.

Reimplemented from Common::MemoryWriteStreamDynamic.

size()

int64 Bagel::SaveReadWriteStream::size ( ) const

inlineoverridevirtual

Obtain the current size of the stream, measured in bytes.

If this value is unknown or cannot be computed, -1 is returned.

Returns

The size of the stream, or -1 if an error occurred.

Reimplemented from Common::MemoryWriteStreamDynamic.
