CPPTarget
public CPPTarget()
escapeChar
public java.lang.String escapeChar(int c)
escapeString
public java.lang.String escapeString(java.lang.String s)
- Converts a String into a representation that can be use as a literal
when surrounded by double-quotes.
Used for escaping semantic predicate strings for exceptions.
- Parameters:
s
- The String to be changed into a literal
genRecognizerHeaderFile
protected void genRecognizerHeaderFile(Tool tool,
CodeGenerator generator,
Grammar grammar,
org.antlr.stringtemplate.StringTemplate headerFileST,
java.lang.String extName)
throws java.io.IOException
- Overrides:
genRecognizerHeaderFile
in class Target
- Throws:
java.io.IOException
getTargetCharLiteralFromANTLRCharLiteral
public java.lang.String getTargetCharLiteralFromANTLRCharLiteral(CodeGenerator codegen,
java.lang.String literal)
- Convert from an ANTLR char literal found in a grammar file to
an equivalent char literal in the target language. For Java, this
is the identify translation; i.e., '\n' -> '\n'. Most languages
will be able to use this 1-to-1 mapping. Expect single quotes
around the incoming literal.
Depending on the charvocabulary the charliteral should be prefixed with a 'L'
- Overrides:
getTargetCharLiteralFromANTLRCharLiteral
in class Target
getTargetStringLiteralFromANTLRStringLiteral
public java.lang.String getTargetStringLiteralFromANTLRStringLiteral(CodeGenerator codegen,
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 identify translation; i.e., "\"\n" -> "\"\n". Most languages
will be able to use this 1-to-1 mapping. Expect double quotes
around the incoming literal.
Depending on the charvocabulary the string should be prefixed with a 'L'
- Overrides:
getTargetStringLiteralFromANTLRStringLiteral
in class Target
getMaxCharValue
public int getMaxCharValue(CodeGenerator codegen)
- Character constants get truncated to this value.
TODO: This should be derived from the charVocabulary. Depending on it
being 255 or 0xFFFF the templates should generate normal character
constants or multibyte ones.
- Overrides:
getMaxCharValue
in class Target
