Method Detail

setBeanProperties

public static Object setBeanProperties(MetaClass mc,
                                       Object bean,
                                       Map properties)

This method is called by the handle to realize the bean constructor with property map.

invokeGroovyObjectInvoker

public static Object invokeGroovyObjectInvoker(MissingMethodException e,
                                               Object receiver,
                                               String name,
                                               Object[] args)

GroovyObject.invokeMethod(String, Object) path as fallback. This method is called by the handle as exception handler in case the selected method causes a MissingMethodExecutionFailed, where we will just give through the exception, and a normal MissingMethodException where we call GroovyObject.invokeMethod(String, Object) if receiver class, the type transported by the exception and the name for the method stored in the exception and our current method name are equal. Should those conditions not apply we just rethrow the exception.

unwrap

public static Object unwrap(GroovyRuntimeException gre)
                     throws Throwable

Unwraps a GroovyRuntimeException. This method is called by the handle to unwrap internal exceptions of the runtime.

Throws:

Throwable

isSameMetaClass

public static boolean isSameMetaClass(MetaClass mc,
                                      Object receiver)

called by handle

unwrap

public static Object unwrap(Object o)

Unwraps a Wrapper. This method is called by the handle to unwrap a Wrapper, which we use to force method selection.

isNull

public static boolean isNull(Object o)

Guard to check if the argument is null. This method is called by the handle to check if the provided argument is null.

sameClass

public static boolean sameClass(Class c,
                                Object o)

Guard to check if the provided Object has the same class as the provided Class. This method will return false if the Object is null.
