Method Detail

optimizeAST

public static ASTLinkedList optimizeAST(ASTLinkedList astLinkedList,
                                        boolean secondPassOptimization,
                                        ParserContext ctx)

Optimize the AST, by reducing any stack-based-operations to dedicated nodes where possible.

Parameters:

astLinkedList - - AST to be optimized.

secondPassOptimization - - perform a second pass optimization to optimize boolean expressions.

ctx - - The parser context

Returns:

optimized AST

extractAllDeclaredFunctions

Returns an ordered Map of all functions declared within an compiled script.

Parameters:

compile -

Returns:

- ordered Map
