ProxyGenerator

public ProxyGenerator()

Method Details

getDebug

public boolean getDebug()

setDebug

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

getEmptyMethods

public boolean getEmptyMethods()

setEmptyMethods

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

getOverride

public ClassLoader getOverride()

setOverride

public void setOverride(ClassLoader override)

List<Class> interfaces,
Object delegate)

instantiateDelegateWithBaseClass

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

instantiateDelegateWithBaseClass

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
