Examples of org.infinispan.objectfilter.ObjectFilter

org.infinispan.objectfilter.ObjectFilter
A filter that tests if an object matches a pre-defined condition and returns either the original instance or the projection, depending on how the filter was created. The projection is represented as an Object[]. If the given instance does not match the filter will just return null. @author anistor@redhat.com @since 7.0
