genRecognizerFile

                                 CodeGenerator generator,
                                 Grammar grammar,

                          throws java.io.IOException

Overrides:

genRecognizerFile in class Target

Throws:

java.io.IOException

genRecognizerHeaderFile

protected void genRecognizerHeaderFile(Tool tool,
                                       CodeGenerator generator,

                                throws java.io.IOException

Overrides:

genRecognizerHeaderFile in class Target

Throws:

chooseWhereCyclicDFAsGo

protected StringTemplate chooseWhereCyclicDFAsGo(Tool tool,
                                                 CodeGenerator generator,
                                                 Grammar grammar,
                                                 StringTemplate recognizerST,
                                                 StringTemplate cyclicDFAST)

isValidActionScope

public boolean isValidActionScope(int grammarType,
                                  java.lang.String scope)

Is scope in @scope::name {action} valid for this kind of grammar? Targets like C++ may want to allow new scopes like headerfile or some such. The action names themselves are not policed at the moment so targets can add template actions w/o having to recompile ANTLR.

Overrides:

isValidActionScope in class Target

getTargetCharLiteralFromANTLRCharLiteral

public java.lang.String getTargetCharLiteralFromANTLRCharLiteral(CodeGenerator generator,
                                                                 java.lang.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

getTargetStringLiteralFromANTLRStringLiteral

public java.lang.String getTargetStringLiteralFromANTLRStringLiteral(CodeGenerator generator,
                                                                     java.lang.String literal)

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:

getTargetStringLiteralFromANTLRStringLiteral in class Target
