ProxyMetaClass (Groovy 4.0.5)

groovy.lang.ProxyMetaClass

All Implemented Interfaces and Traits:

AdaptingMetaClass
```
public class ProxyMetaClass
extends MetaClassImpl
implements AdaptingMetaClass
```
As subclass of MetaClass, ProxyMetaClass manages calls from Groovy Objects to POJOs. It enriches MetaClass with the feature of making method invocations interceptable by an Interceptor. To this end, it acts as a decorator (decorator pattern) allowing to add or withdraw this feature at runtime. See groovy/lang/InterceptorTest.groovy for details.
WARNING: This implementation of ProxyMetaClass is NOT thread-safe and hence should only be used for as a per-instance MetaClass running in a single thread. Do not place this MetaClass in the MetaClassRegistry as it will result in unpredictable behaviour

- Constructor Detail
  - public ProxyMetaClass(MetaClassRegistry registry, Class theClass, MetaClass adaptee)
    
    Parameters:
    adaptee - the MetaClass to decorate with interceptability
- Method Detail
  - @Override
    public MetaClass getAdaptee()
  - public static ProxyMetaClass getInstance(Class theClass)
    
    convenience factory method for the most usual case.
  - public Interceptor getInterceptor()
    
    Returns:
    the interceptor in use or null if no interceptor is used
  - @Override
    public Object getProperty(Class aClass, Object object, String property, boolean useSuper, boolean fromInsideClass)
    
    Interceptors the call to getProperty if a PropertyAccessInterceptor is available
    Parameters:
    object - the object to invoke the getter on
    property - the property name
    Returns:
    the value of the property
  - @Override
    public void initialize()
  - @Override
    public Object invokeConstructor(Object[] arguments)
    
    Call invokeConstructor on adaptee with logic like in MetaClass unless we have an Interceptor. With Interceptor the call is nested in its beforeInvoke and afterInvoke methods. The method call is suppressed if Interceptor.doInvoke() returns false. See Interceptor for details.
  - @Override
    public Object invokeMethod(Object object, String methodName, Object[] arguments)
    
    Call invokeMethod on adaptee with logic like in MetaClass unless we have an Interceptor. With Interceptor the call is nested in its beforeInvoke and afterInvoke methods. The method call is suppressed if Interceptor.doInvoke() returns false. See Interceptor for details.
  - @Override
    public Object invokeMethod(Class sender, Object object, String methodName, Object[] arguments, boolean isCallToSuper, boolean fromInsideClass)
    
    Call invokeMethod on adaptee with logic like in MetaClass unless we have an Interceptor. With Interceptor the call is nested in its beforeInvoke and afterInvoke methods. The method call is suppressed if Interceptor.doInvoke() returns false. See Interceptor for details.
  - @Override
    public Object invokeStaticMethod(Object object, String methodName, Object[] arguments)
    
    Call invokeStaticMethod on adaptee with logic like in MetaClass unless we have an Interceptor. With Interceptor the call is nested in its beforeInvoke and afterInvoke methods. The method call is suppressed if Interceptor.doInvoke() returns false. See Interceptor for details.
  - @Override
    public void setAdaptee(MetaClass metaClass)
  - public void setInterceptor(Interceptor interceptor)
    
    Parameters:
    interceptor - may be null to reset any interception
  - @Override
    public void setProperty(Class aClass, Object object, String property, Object newValue, boolean useSuper, boolean fromInsideClass)
    
    Interceptors the call to a property setter if a PropertyAccessInterceptor is available
    Parameters:
    object - The object to invoke the setter on
    property - The property name to set
    newValue - The new value of the property
  - public Object use(Closure closure)
    
    Use the ProxyMetaClass for the given Closure. Cares for balanced register/unregister.
    Parameters:
    closure - piece of code to be executed with registered ProxyMetaClass
  - public Object use(GroovyObject object, Closure closure)
    
    Use the ProxyMetaClass for the given Closure. Cares for balanced setting/unsetting ProxyMetaClass.
    Parameters:
    closure - piece of code to be executed with ProxyMetaClass
