Predefined attributes
|
|
Used for the parser constructors to identify non-standard attributes
|
|
|
|
Override these to change the attribute to your own unique identifier convention.
|
|
|
|
The tokenizer identifies attribute defines with the GEN_DEFINE_ATTRIBUTE_TOKENS macros.
|
|
See the example below and the Define_TokType macro used in gen.cpp to know the format.
|
|
While the library can parse raw attributes, most projects use defines to wrap them for compiler
|
|
platform indendence. The token define allows support for them without having to modify the library.
