configure

public void configure(org.apache.avalon.framework.configuration.Configuration conf)
               throws org.apache.avalon.framework.configuration.ConfigurationException

Description copied from class: AbstractConfigurableAction

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.

act

public java.util.Map act(Redirector redirector,
                         SourceResolver resolver,
                         java.util.Map objectModel,

                         org.apache.avalon.framework.parameters.Parameters parameters)
                  throws java.lang.Exception

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.

Following copied from interface: org.apache.cocoon.acting.Action

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:

java.lang.Exception - Indicates something is totally wrong
