java.lang.Objectorg.jgroups.blocks.MethodCall
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.
Field Summary | |
protected java.lang.Object[] |
args
the arguments of the method |
protected java.lang.reflect.Method |
method
the Method of the call |
protected static short |
METHOD
explicitly ship the method, caller has to determine method himself |
protected java.lang.String |
method_name
the name of the method, case sensitive |
protected short |
mode
which mode to use |
protected static short |
OLD
infer the method from the arguments |
protected java.lang.String[] |
signature
the signature, e.g. |
protected static short |
SIGNATURE
provide a signature, similar to JMX |
protected java.lang.Class[] |
types
the class types, e.g. |
protected static short |
TYPES
use class information |
