useBaseTemplatesForSynPredFragments

public boolean useBaseTemplatesForSynPredFragments()

Overrides:

useBaseTemplatesForSynPredFragments in class Target

getTokenTypeAsTargetLabel

public String getTokenTypeAsTargetLabel(CodeGenerator generator,
                               int ttype)

Target must be able to override the labels used for token types

Overrides:

getTokenTypeAsTargetLabel in class Target

getTargetCharLiteralFromANTLRCharLiteral

public String getTargetCharLiteralFromANTLRCharLiteral(CodeGenerator generator,
                                              String literal)

Description copied from class: Target

Convert from an ANTLR char literal found in a grammar file to an equivalent char literal in the target language. For most languages, this means leaving 'x' as 'x'. Actually, we need to escape ' ' so that it doesn't get converted to \n by the compiler. Convert the literal to the char value and then to an appropriate target char literal. Expect single quotes around the incoming literal.

Overrides:

getTargetCharLiteralFromANTLRCharLiteral in class Target

postProcessAction

public List<Object> postProcessAction(List<Object> chunks,
                             Token actionToken)

Description copied from class: Target

Give target a chance to do some postprocessing on actions. Python for example will have to fix the indention.

Overrides:

postProcessAction in class Target
