Detailed Description

This is a MemoryReadStream subclass which adds non-endian read methods whose endianness is set on the stream creation.

Member Function Documentation

◆ pos()

int64 Common::MemoryReadStreamEndian::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::MemoryReadStream.

◆ size()

int64 Common::MemoryReadStreamEndian::size ( ) const
inlineoverridevirtual

Obtain the total 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::MemoryReadStream.

◆ seek()

bool Common::MemoryReadStreamEndian::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
offsetRelative offset in bytes.
whenceSeek reference: SEEK_SET, SEEK_CUR, or SEEK_END.
Returns
True on success, false in case of a failure.

Reimplemented from Common::MemoryReadStream.

◆ skip()

bool Common::MemoryReadStreamEndian::skip ( uint32  offset)
inlineoverridevirtual

Skip the given number of bytes in the stream.

This is equivalent to calling:

seek(offset, SEEK_CUR)

to add the given number of bytes to the current position indicator of the stream.

Returns
True on success, false in case of a failure.

Reimplemented from Common::SeekableReadStream.
