genRule

public void genRule(antlr.RuleSymbol s)

Generate code for a named rule block

Parameters:: s - The RuleSymbol describing the rule to generate

getASTCreateString

public java.lang.String getASTCreateString(Vector v)

Get a string for an expression to generate creation of an AST subtree.

Specified by:: getASTCreateString in class CodeGenerator

Parameters:: v - A Vector of String, where each element is an expression in the target language yielding an AST node.

getASTCreateString

public java.lang.String getASTCreateString(antlr.GrammarAtom atom,

Specified by:: mapTreeId in class CodeGenerator

Parameters:: id - The identifier name to map
Returns:: The mapped id (which may be the same as the input), or null if the mapping is invalid due to duplicates

printSet
