@java.lang.SuppressWarnings({"unchecked","rawtypes"}) public class ProxyMetaClass extends groovy.lang.MetaClassImpl
As subclass of MetaClass, ProxyMetaClass manages calls from Groovy Objects to POJOs. It enriches MetaClass with the feature of making method invokations interceptable by an Interceptor. To this end, it acts as a decorator (decorator pattern) allowing to add or withdraw this feature at runtime. This is based on original code by Dierk Koenig, but uses a callback object for thread safety and supports not only method interception, but property and constructor interception too.
