Class ScriptMediatorFactory

java.lang.Object
  org.apache.synapse.config.xml.AbstractMediatorFactory
      org.apache.synapse.mediators.bsf.ScriptMediatorFactory

All Implemented Interfaces:

MediatorFactory

public class ScriptMediatorFactory
extends AbstractMediatorFactory

Creates an instance of a Script mediator for inline or external script mediation for BSF scripting languages.

*

    <script [key="entry-key"]
      [function="script-function-name"] language="javascript|groovy|ruby">
      (text | xml)?
      <include key="entry-key" />
    </script>
 

The boolean response from the in-lined mediator is either the response from the evaluation of the script statements or if that result is not a boolean then a response of true is assumed.

The MessageContext passed in to the script mediator has additional methods over the Synapse MessageContext to enable working with the XML in a way natural to the scripting language. For example when using JavaScript get/setPayloadXML use E4X XML objects, when using Ruby they use REXML documents.

For external script mediation, that is when using key, function, language attributes, <include key"entry-key" /> is used to include one or more additional script files.
