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.
