Class MapBinding

java.lang.Object
  org.jbpm.wire.binding.MapBinding

All Implemented Interfaces:

Binding

public class MapBinding
extends java.lang.Object
implements Binding

This Binding specifies a MapDescriptor.

A Map descriptor is defined by a <map> xml element.

This element can have an attribute "name", which specifies the name of the created object in the WireContext.

This element can have an attribute "class", which specifies the implementation of Map to use. If this attribute is not present, the HashMap implementation is used.

Map entries

Entries to add to the map can be specified with <entry> elements.

Each <entry> must contain a <key> element and a <value> element.

Each <key> and <value> elements should contain a Descriptor element.

Example

The following Xml declaration will create a TreeMap, and store it under the name 'm'. The map will contain two elements:

• 'a' associated with the key 'foo'
• 'b' associated with the key 'bar'

 <objects>
   <map name='m' class='java.util.TreeMap' >
     <entry>
       <key> <string value='foo'/> </key>
       <value> <object name='a' class='java.lang.Object' /> </value>
     </entry>
     <entry>
       <key> <string value='bar'/> </key>
       <value> <object name='b' class='java.lang.Object' /> </value>
     </entry>
   </map>
 </objects>
