getTargetCharLiteralFromANTLRCharLiteral
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 classTarget
-
getTargetStringLiteralFromANTLRStringLiteral
Convert from an ANTLR string literal found in a grammar file to an equivalent string literal in the target language. For Java, this is the translation 'a\n"' -> "a\n\"". Expect single quotes around the incoming literal. Just flip the quotes and replace double quotes with \"- Overrides:

in classTarget

getTokenTypeAsTargetLabel
If we have a label, prefix it with the recognizer's name- Overrides:
getTokenTypeAsTargetLabel
in classTarget
-
getTokenTextAndTypeAsTargetLabel
Target must be able to override the labels used for token types. Sometimes also depends on the token text.
