MethodAccess

protected MethodAccess(Class type)

方法详细资料

getIndex

public abstract int getIndex(String name,
 Class[] parameterTypes)

Return the index of the matching method. The index may be used later to invoke the method with less overhead. If more than one method matches (i.e. they differ by return type only), one is chosen arbitrarily.

参数:

name - the method name

parameterTypes - the parameter array

返回:

the index, or -1 if none is found.

另请参阅:

• invoke(int, Object, Object[])

getIndex

public abstract int getIndex(Class[] parameterTypes)

Return the index of the matching constructor. The index may be used later to create a new instance with less overhead.

参数:

parameterTypes - the parameter array

返回:

the constructor index, or -1 if none is found.

另请参阅:

• newInstance(int, Object[])

invoke

public abstract Object invoke(int index,
 Object obj,
 Object[] args)
                       throws InvocationTargetException

Invoke the method with the specified index.

参数:

index - the method index

obj - the object the underlying method is invoked from

args - the arguments used for the method call

抛出:

InvocationTargetException - if the underlying method throws an exception

另请参阅:

• getIndex(String, Class[])

newInstance

public abstract Object newInstance(int index,
 Object[] args)
                            throws InvocationTargetException

Create a new instance using the specified constructor index and arguments.

参数:

index - the constructor index

args - the arguments passed to the constructor

抛出:

InvocationTargetException - if the constructor throws an exception

• getIndex(Class[])
