Detailed Description

Simple matcher expression parser.

The parser understands matcher expressions of the form: MatcherName(Arg0, Arg1, ..., ArgN) as well as simple types like strings. The parser does not know how to process the matchers. It delegates this task to a Sema object received as an argument.

 Grammar for the expressions supported:
 <Expression>        := <Literal> | <NamedValue> | <MatcherExpression>
 <Literal>           := <StringLiteral> | <Unsigned>
 <StringLiteral>     := "quoted string"
 <Unsigned>          := [0-9]+
 <NamedValue>        := <Identifier>
 <MatcherExpression> := <Identifier>(<ArgumentList>) |
                        <Identifier>(<ArgumentList>).bind(<StringLiteral>)
 <Identifier>        := [a-zA-Z]+
 <ArgumentList>      := <Expression> | <Expression>,<ArgumentList>
