Attributes

syn TypeDecl type()
Description copied from class: NumericLiteral
The type of a NumericLiteral is undefined. The literal must be parsed before it can have a type.
Overrides:type in class NumericLiteral

Literals
syn Constant constant()
Parse this literal and return a fresh Constant.
Overrides:constant in class Literal
Returns:
a fresh Constant representing this FloatingPointLiteral

syn boolean needsRewrite()
Utility attribute for literal rewriting. Any of the NumericLiteral subclasses have already been rewritten and/or parsed, and should not be rewritten again.
Overrides:needsRewrite in class NumericLiteral
Returns:
true if this literal is a "raw", not-yet-parsed NumericLiteral
