public class DataSourceBeanFilter
extends java.lang.Object

An IBeanFilter that applies DataSource.getProperties() to all bean values (e.g. applying valueXPath) and optionally strips any bean properties that do not have a corresponding DataSource field definition.
Note: this filter is automatically applied by the RPCManager to all DSResponse objects sent to the client in order to perform valueXPath resolution.
