Package io.github.douira.glsl_transformer.basic

Class CachingParser

java.lang.Object

io.github.douira.glsl_transformer.basic.EnhancedParser

io.github.douira.glsl_transformer.basic.CachingParser

All Implemented Interfaces:

ParserInterface

public class CachingParser
extends EnhancedParser

The caching parser extends the enhanced parser and returns previous parse trees if they are available. This can't be used if the parse tree is modified after parsing since then the contents of the cache would be modified too. The ASTBuilder does not modify the parse tree, and therefore it is safe to use this.
