Field Detail

methodMapArray

private static final Method[] methodMapArray

Array containing element pairs in which each pair of elements represents a mapping between two methods having the following characteristics:

• the first element in the pair is one of the public, remote method(s) that may be invoked by the client through AdminIterator.
• the second element in the pair is the method, implemented in the backend server class, that is ultimately executed in the server's backend when the client invokes the corresponding method in this proxy.

Constructor Detail

ConstrainableIteratorProxy

ConstrainableIteratorProxy(Uuid iterationUuid,
                           OutriggerAdmin server,
                           int fetchSize,
                           MethodConstraints methodConstraints)

Create a new ConstrainableIteratorProxy.

Parameters:

iterationUuid - The identity of the iteration this proxy is for.

server - reference to remote server for the space.

fetchSize - Number of entries to ask for when it goes to the server

methodConstraints - the client method constraints to place on this proxy (may be null).

Throws:

NullPointerException - if server or iterationUuid is null.

ClassCastException - if server does not implement RemoteMethodControl.

Method Detail

constrainServer

private static OutriggerAdmin constrainServer(OutriggerAdmin server,
                                              MethodConstraints constraints)

Returns a copy of the given OutriggerAdmin proxy having the client method constraints that result after mapping defined by methodMapArray is applied.

Parameters:

server - The proxy to attach constrains too.

constraints - The source method constraints.

Throws:

NullPointerException - if server is null.

ClassCastException - if server does not implement RemoteMethodControl.
