Class RemoteInvocation

java.lang.Object
  org.springframework.remoting.support.RemoteInvocation

All Implemented Interfaces:

Serializable

public class RemoteInvocation
extends Object
implements Serializable

Encapsulates a remote invocation, providing core method invocation properties in a serializable fashion. Used for RMI and HTTP-based serialization invokers.

This is an SPI class, typically not used directly by applications. Can be subclassed for additional invocation parameters.

Constructor Detail

RemoteInvocation

public RemoteInvocation()

Create a new RemoteInvocation for use as JavaBean.

RemoteInvocation

public RemoteInvocation(String methodName,
                        Class[] parameterTypes,
                        Object[] arguments)

Create a new RemoteInvocation for the given parameters.

Parameters:

methodName - the name of the method to invoke

parameterTypes - the parameter types of the method

arguments - the arguments for the invocation

RemoteInvocation

public RemoteInvocation(MethodInvocation methodInvocation)

Create a new RemoteInvocation for the given AOP method invocation.

Parameters:

methodInvocation - the AOP invocation to convert

Method Detail

setMethodName

public void setMethodName(String methodName)

getMethodName

public String getMethodName()

setParameterTypes

public void setParameterTypes(Class[] parameterTypes)

getParameterTypes

public Class[] getParameterTypes()

setArguments

public void setArguments(Object[] arguments)

getArguments

public Object[] getArguments()

addAttribute

public void addAttribute(String key,
                         Serializable value)

Add an additional invocation attribute. Useful to add additional invocation context without having to subclass RemoteInvocation.

Attribute keys have to be unique, and no overriding of existing attributes is allowed.

The implementation avoids to unnecessarily create the attributes Map, to minimize serialization size.

Parameters:

key - the attribute key

value - the attribute value

getAttribute

public Serializable getAttribute(String key)

Retrieve the attribute for the given key, if any.

The implementation avoids to unnecessarily create the attributes Map, to minimize serialization size.

Parameters:

key - the attribute key

Returns:

the attribute value, or null if not defined

setAttributes

public void setAttributes(Map attributes)

Set the attributes Map. Only here for special needs: Preferably, use addAttribute and getAttribute.

Parameters:

attributes - the attributes Map

See Also:

addAttribute(java.lang.String, java.io.Serializable), getAttribute(java.lang.String)

getAttributes

public Map getAttributes()

Return the attributes Map. Mainly here for debugging purposes: Preferably, use addAttribute and getAttribute.

Returns:

the attributes Map, or null if none created

See Also:

addAttribute(java.lang.String, java.io.Serializable), getAttribute(java.lang.String)

invoke

public Object invoke(Object targetObject)
              throws NoSuchMethodException,
                     IllegalAccessException,
                     InvocationTargetException

Perform this invocation on the given target object. Typically called when a RemoteInvocation is received on the server.

Parameters:

targetObject - the target object to apply the invocation to

Returns:

the invocation result

Throws:

NoSuchMethodException - if the method name could not be resolved

IllegalAccessException - if the method could not be accessed

InvocationTargetException - if the method invocation resulted in an exception

Method.invoke(java.lang.Object, java.lang.Object...)

toString

public String toString()

Overrides:

toString in class Object
