Processes a method invocation on a proxy instance and returns the result.

abstract member Invoke : Java.Lang.Object * Java.Lang.Reflect.Method * Java.Lang.Object[] -> Java.Lang.Object

Parameters

proxy: Object

the proxy instance that the method was invoked on

method: Method

the Method instance corresponding to the interface method invoked on the proxy instance. The declaring class of the Method object will be the interface that the method was declared in, which may be a superinterface of the proxy interface that the proxy class inherits the method through.

args: Object[]

an array of objects containing the values of the arguments passed in the method invocation on the proxy instance, or null if interface method takes no arguments. Arguments of primitive types are wrapped in instances of the appropriate primitive wrapper class, such as java.lang.Integer or java.lang.Boolean.

Returns

Object

the value to return from the method invocation on the proxy instance. If the declared return type of the interface method is a primitive type, then the value returned by this method must be an instance of the corresponding primitive wrapper class; otherwise, it must be a type assignable to the declared return type. If the value returned by this method is null and the interface method's return type is primitive, then a NullPointerException will be thrown by the method invocation on the proxy instance. If the value returned by this method is otherwise not compatible with the interface method's declared return type as described above, a ClassCastException will be thrown by the method invocation on the proxy instance.

Attributes: RegisterAttribute

Exceptions

Throwable

the exception to throw from the invoked method on the proxy. The exception must match one of the declared exception types of the invoked method or any unchecked exception type. If not then an UndeclaredThrowableException is thrown

Remarks

Processes a method invocation on a proxy instance and returns the result. This method will be invoked on an invocation handler when a method is invoked on a proxy instance that it is associated with.
