All Implemented Interfaces:: java.lang.Cloneable, java.lang.Iterable<ASTNode>

Direct Known Subclasses:: DoubleLiteral, FloatingPointLiteral, IntegerLiteral, LongLiteral

Description

Attributes

syn long parseLong()

This is a refactored version of Literal.parseLong which supports binary literals. This version of parseLong is implemented as an attribute rather than a static method. Perhaps some slight performance boost could be gained from keeping it static, but with the loss of declarative- and ReRAGness. There exists only a parseLong, and not a parseInteger. Parsing of regular integer literals works the same, but with stricter bounds requirements on the resulting parsed value.
