Detailed Description

A parser for the Bond scripting language.

The Parser parses the contents of a TokenCollection generated from a Lexer that has scanned Bond source code. Its output is a parse tree of objects that derive from ParseNode. The concrete type of the root node is TranslationUnit. The parse tree can then be used as input to a SemanticAnalyzer and CodeGenerator. A single Parser can be used to parse several collections of Tokens.

When writing a tool that requires a compiler front end, the interactions between the front end components, namely a Lexer, a Parser and a SemanticAnalyzer, can be managed by a FrontEnd.
