public GroovyObject instantiateAggregate(Map closureMap, List<Class> interfaces)

public GroovyObject instantiateAggregate(Map closureMap, List<Class> interfaces, Class clazz)

public GroovyObject instantiateAggregateFromInterface(Class clazz)

public GroovyObject instantiateAggregateFromInterface(Map map, Class clazz)

public GroovyObject instantiateDelegate(Object delegate)

public GroovyObject instantiateDelegate(List<Class> interfaces, Object delegate)

public GroovyObject instantiateDelegate(Map closureMap, List<Class> interfaces, Object delegate)

public GroovyObject instantiateDelegateWithBaseClass(Map closureMap, List<Class> interfaces, Object delegate)

public GroovyObject instantiateDelegateWithBaseClass(Map closureMap, List<Class> interfaces, Object delegate, Class baseClass)

@SuppressWarnings("unchecked") public GroovyObject instantiateDelegateWithBaseClass(Map closureMap, List<Class> interfaces, Object delegate, Class baseClass, String name)

Creates a proxy with a delegate object.

Parameters:: closureMap - the closure for methods not handled by the delegate; interfaces - interfaces to be implemented; delegate - the delegate object; baseClass - the base class; name - the name of the proxy, unused, but kept for compatibility with previous versions of Groovy.

Returns:: a proxy object implementing the specified interfaces, and delegating to the provided object

public void setDebug(boolean debug)

Instructs ProxyGenerator to dump generated Groovy source code to standard output during construction. This is useful for debugging purposes but should be turned off in production.

Parameters:: debug - true if you want generated source to be printed

public void setEmptyMethods(boolean emptyMethods)

Changes generated methods to have empty implementations.

Methods in generated aggregates not supplied in a closures map or base class are given 'default' implementations. The implementation will normally throw an UnsupportedOperationException but setting this boolean will leave it empty.

Parameters:: emptyMethods - true if you want generated methods to be empty

public void setOverride(ClassLoader override)
