public class WriteProcessingCallbackParams
extends Object

callback params class scaffolding arbitrary parameters supplied to callback and providing access API, The parameters sample: <ul> <li><Param name="foo" x="a" y="b"/></li> <li><Param name="foo" z="x" d="y"/></li> <li><Param name="bindingItem" id="bcdUpdateBy" value="expression" isCoalesce="true"/></li> <li><Param name="bindingItem" id="bcdUpdateStamp" value="expression" isCoalesce="false"/></li> </ul> the parameter api is a list of parameter-maps in the order they are defined. The parameters however, are not ordered. The definition above would result in a list of maps: 1st map: name=foo, x=a, y=b 2nd map: name=foo, z=x, d=y 3rd map: name=bindingItem, id=bcdUpdateBy, value=expression, isCoalesce=true etc. This class may be extended with convenience API for parameter retrieval, i.e. by param/name
