Description copied from interface: Action

Controls the processing against some values of the Dictionary objectModel and returns a Map object with values used in subsequent sitemap substitution patterns. NOTE: This interface is designed so that implentations can be ThreadSafe. When an action is ThreadSafe, only one instance serves all requests : this reduces memory usage and avoids pooling.

Specified by:

act in interface Action

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
