public abstract class AbstractMethodInvokingDelegator<T>
extends java.lang.Object
implements org.springframework.beans.factory.InitializingBean
```
Superclass for delegating classes which dynamically call a custom method of injected object. Provides convenient API for dynamic method invocation shielding subclasses from low-level details and exception handling. Exceptions thrown by a successfully invoked delegate method are re-thrown without wrapping. In case the delegate method throws a Throwable that doesn't subclass Exception it will be wrapped by AbstractMethodInvokingDelegator.InvocationTargetThrowableWrapper.

  - invokeDelegateMethod
```
protected T invokeDelegateMethod()
                          throws java.lang.Exception
```
    Invoker the target method with arguments set by setArguments(Object[]).
    返回:
    object returned by invoked method
    抛出:
    java.lang.Exception - exception thrown when executing the delegate method.
  - invokeDelegateMethodWithArgument
```
protected T invokeDelegateMethodWithArgument(java.lang.Object object)
                                      throws java.lang.Exception
```
    Invokes the target method with given argument.
    参数:
    object - argument for the target method
    返回:
    object returned by target method
    抛出:
    java.lang.Exception - exception thrown when executing the delegate method.
  - invokeDelegateMethodWithArguments
```
protected T invokeDelegateMethodWithArguments(java.lang.Object[] args)
                                       throws java.lang.Exception
```
    Invokes the target method with given arguments.
    参数:
    args - arguments for the invoked method
    返回:
    object returned by invoked method
    抛出:
    java.lang.Exception - exception thrown when executing the delegate method.
  - afterPropertiesSet
```
public void afterPropertiesSet()
                        throws java.lang.Exception
```
    指定者:
    afterPropertiesSet 在接口中 org.springframework.beans.factory.InitializingBean
    抛出:
    java.lang.Exception
  - setTargetObject
```
public void setTargetObject(java.lang.Object targetObject)
```
    参数:
    targetObject - the delegate - bean id can be used to set this value in Spring configuration
  - setTargetMethod
```
public void setTargetMethod(java.lang.String targetMethod)
```
    参数:
    targetMethod - name of the method to be invoked on setTargetObject(Object).
  - setArguments
```
public void setArguments(java.lang.Object[] arguments)
```
    参数:
    arguments - arguments values for the { setTargetMethod(String). These will be used only when the subclass tries to invoke the target method without providing explicit argument values. If arguments are set to not-null value afterPropertiesSet() will check the values are compatible with target method's signature. In case arguments are null (not set) method signature will not be checked and it is assumed correct values will be supplied at runtime.
  - getArguments
```
protected java.lang.Object[] getArguments()
```
    Return arguments.
    返回:
    arguments
