Function Documentation

build_tag_data_segment()

std::vector<char> build_tag_data_segment	(	int	start_offset,
		int	base_size,
		std::vector< BlamTagField * >	fields
	)

Compiles a list of tag fields into a binary format.

Parameters

start_offset	- Offset pointing immediately after the main field data. Used when building referenced data within a tag segment.
base_size	- The base size of the list of fields.
fields	- The list of fields to compile.

Returns

A list of bytes representing the tag's compiled data.

Todo:

fix dataref compilation issue where next_block_file_offset is somehow wrong

decompile_tag_segment()

std::vector<BlamTagField*> decompile_tag_segment	(	BlamTag *	tag,
		std::vector< BlamPluginField * >	fields,
		int	base_size,
		std::ifstream *	tag_file,
		int	start_offset
	)

Decompiles a compiled tag segment.

This is used to decompile tag data for use within Guerilla. A "segment" in this case simply refers to either the base tag data, or a tag block's entry data.

Parameters

tag	- The tag being decompiled.
fields	- The list of plugin fields associated with this segment.
base_size	- The size of the tag segment.
tag_file	- The input file stream to read data from.
start_offset	- The offset in the file where the segment data begins.

Todo:

Decompile support for tagrefs

Returns

A list of decompiled tag fields.
