public interface PrefixSyntaxInterface

The PrefixSyntaxInterface interface should be implemented by any class which provides a piece of prefix syntax. Prefix syntax is that which preceeds the expression it operates on. An instance of this class may be responsible for more than one symbol, e.g in the case of if and unless, which have the same syntax.

Method Summary

Expr	prefix(java.lang.String sym, Parser parser) Parse the syntax for the specified symbol, using the specified Parser.

Method Detail

prefix

Expr prefix(java.lang.String sym,
            Parser parser)

Parse the syntax for the specified symbol, using the specified Parser. The symbol is specified because different symbols may share the same syntax, but result in slightly different expressions. The Parser is supplied as the source to parse from.

Parameters:

sym - the symbol to parse this syntax for

parser - Parser to parse from, i.e. the source to parse from

Returns:

an expression for this syntax
