	To parse an 0x27 block, we need to know where the end of the block is in the stream.

Detailed Description

The block parser is responsible for parsing individual blocks of data from the file stream.

Most blocks don't need much context to parse in a binary sense, but most need to know the version, and one (0x27) needs to know where the end of the block is.

Member Function Documentation

◆ ParseBlock()

std::unique_ptr< BLOCK_BASE > ALLEGRO::BLOCK_PARSER::ParseBlock ( bool & aEndOfObjectsMarker )

Parse one block from the stream, returning a BLOCK_BASE representing the raw data of the block.

Parameters

aStream	The stream to read from, positioned at the start of the block (i.e. the next byte to read is the block type).
aEndOfObjectsMarker	This is set to true if we encounter the end of objects marker.
