Controls the processing against some values of the Dictionary objectModel and returns a Map object with values used in subsequent sitemap substitution patterns.

Parameters:
resolver - The SourceResolver in charge
objectModel - The Map with object of the calling environment which can be used to select values this controller may need (ie Request, Response).
source - A source String to the Action
parameters - The Parameters for this invocation
Returns:
Map The returned Map object with sitemap substitution values which can be used in subsequent elements attributes like src= using a xpath like expression: src="mydir/{myval}/foo" If the return value is null the processing inside the element of the sitemap will be skipped.
Throws:
Exception - Indicates something is totally wrong
