PostfixSyntaxInterface

public final class DotSyntax
extends PostfixSyntax

This class implements dot syntax. The dot syntax is used for function applications, allowing you to put function arguments on the left hand side of the function expression.

<expr>.<expr>

The left hand side expression will be used as the first of the function arguments. The right hand side expression is made up of a function expression, optionally followed by any more arguments for the function.

Description copied from interface: PostfixSyntaxInterface

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. As this is postfix syntax, we are also supplied the expression on the left hand side of the symbol along with the current precedence we should parse to.

Specified by:

postfix in interface PostfixSyntaxInterface

Specified by:

postfix in class PostfixSyntax

Parameters:

sym - the symbol to parse this syntax for

prec - the current precedence we should parse to

lhs - the expression on the left hand side of the specified symbol

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

Returns:

an expression for this syntax
