Class MethodCall
java.lang.Object
org.jgroups.blocks.MethodCall
- Externalizable
public class MethodCall
extends java.lang.Object
implements Externalizable
A method call is the JavaGroup 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.

protected static short | METHOD - explicitly ship the method, caller has to determine method himself
|
protected static short | OLD - infer the method from the arguments
|
protected static short | SIGNATURE - provide a signature, similar to JMX
|
protected static short | TYPES - use class information
|
protected Object[] | args - the arguments of the method
|
protected static Log | log
|
protected Method | method - the Method of the call
|
protected String | method_name - the name of the method, case sensitive
|
protected short | mode - which mode to use
|
protected String[] | signature - the signature, e.g.
|
protected Class[] | types - the class types, e.g.
|
MethodCall() - creates an empty method call, this is always invalid, until
setName() has been called
|
MethodCall(Method method)
|
MethodCall(Method method, Object[] arguments)
|
MethodCall(String method_name, Object[] args) - Use one of the constructors that take class types as arguments
|
MethodCall(String method_name, Object[] args, Class[] types)
|
MethodCall(String method_name, Object[] args, String[] signature)
|
Object[] | getArgs() - returns an ordered list of arguments used for the method invokation
|
Method | getMethod()
|
int | getMode()
|
String | getName() - returns the name of the method to be invoked using this method call object
|
Object | invoke(Object target) - Invokes the method with the supplied arguments against the target object.
|
Object | invoke(Object target, Object[] args)
|
void | readExternal(ObjectInput in)
|
void | setArgs(Object[] args)
|
void | setName(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
|
String | toString()

String | toStringDetails()
|
void | writeExternal(ObjectOutput out)

- returns the list of ordered arguments
getMethod
public Method getMethod()
getMode
public int getMode()
getName
public String getName()
returns the name of the method to be invoked using this method call object
- a case sensitive name, can be null for an invalid method call
invoke
public Object invoke(Object target)
throws Throwable
Invokes the method with the supplied arguments against the target object.
If a method lookup is provided, it will be used. Otherwise, the default
method lookup will be used.
target
- - the object that you want to invoke the method on
- an object

a different method invokation of a different method
n
- - a case sensitive method name
toString
