Simple helper action to allow passing sitemap variables to InputModules.
Sitemap evaluation of input modules using the curly bracket syntax e.g.
{defaults:skin} suffers from the fact that it is not
possible to use a sitemap variable as part of the invocation like
{defaults:{1})}. This action takes three parameters, the name
of the input module, the attribute name, and whether to call getAttribute() or
getAttributeValues(). Thus the above becomes
<map:act type="inputmodule">
<map:parameter name="module" value="defaults"/>
<map:parameter name="attribute" value="{1}"/>
<map:parameter name="single-value" value="false"/>
<!-- do something with the result: "{1}" -->
</map:act>
The action invokes the
getAttributeValues()
method and returns all results numbered from "0". If no result exists,
"null" is returned and the nested block is skipped.
The name of the input module to use may be preconfigured when
declaring the action in your sitemap:
act(Redirector redirector,
SourceResolver resolver,
Map objectModel,
String source,
Parameters parameters)
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.
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.
Configures the Action.
Takes the children from the Configuration and stores them
them as key (configuration name) and value (configuration value)
in settings.
This automates parsing of flat string-only configurations.
For nested configurations, override this function in your action.
