com.fr.third.jgroups.blocks.MethodCall

所有已实现的接口:

Streamable, java.io.Externalizable, java.io.Serializable

public class MethodCall
extends java.lang.Object
implements java.io.Externalizable, Streamable

A method call is the JGroups representation of a remote method. It includes the name of the method (case sensitive) and a list of arguments. A method call is serializable and can be passed over the wire.

          java.lang.Class[] types)

方法详细资料

lookup

public MethodCall lookup(MethodLookup lookup)

getMode

public int getMode()

getName

public java.lang.String getName()

returns the name of the method to be invoked using this method call object

返回:

a case sensitive name, can be null for an invalid method call

setName

public void setName(java.lang.String n)

sets the name for this MethodCall and allowing you to reuse the same object for a different method invokation of a different method

参数:

n - - a case sensitive method name

getId

public short getId()

setId

public void setId(short method_id)

getArgs

public java.lang.Object[] getArgs()

returns an ordered list of arguments used for the method invokation

target - - the object that you want to invoke the method on

返回:

an object
