Class ChangeRequest

java.lang.Object

ch.dermitza.securenio.ChangeRequest

public final class ChangeRequest
extends java.lang.Object

A ChangeRequest defines a request for some operation that needs to be executed on the selector thread. ChangeRequests are created and queued from threads that interact with the selector thread and are necessary as the result of some particular operation being completed (e.g. an SSLEngineTask having finished).

Field Detail

TYPE_TASK

public static final int TYPE_TASK

This type concerns an SSLEngine task that has just finished running on the TaskWorker thread.

This type of task is used if and only if the SecureSocket is processing tasks via the TaskWorker thread (multi-threaded implementation).

TYPE_OPS

public static final int TYPE_OPS

This type concerns switching the interestOps of a key associated with a particular socket.

Constant Field Values

TYPE_TIMEOUT

public static final int TYPE_TIMEOUT

This type concerns a timeout that has expired on the given socket. As such, the socket needs to be closed.

TYPE_SESSION

public static final int TYPE_SESSION

This type concerns an SSLSession that has been invalidated. As such, we need to re-initiate handshaking.

ChangeRequest

public ChangeRequest(SocketIF sc,
             int type,
             int interestOps)

A ChangeRequest defines a request for some operation that needs to be executed on the selector thread. ChangeRequests are created and queued from threads that interact with the selector thread and are necessary as the result of some particular operation being completed (e.g. an SSLEngine task having finished).

Parameters:

sc - The SocketIF associated with this ChangeRequest

type - The type associated with this ChangeRequest

interestOps - The interestOps (SelectionKey.interestOps) associated with this ChangeRequest. If the type of this ChangeRequest is anything other than TYPE_OPS, the interestOps can be set to anything safely.

Method Detail

getChannel

public SocketIF getChannel()

Get the SocketIF associated with this ChangeRequest

Returns:

The SocketIF associated with this ChangeRequest

getType

public int getType()

Get the type associated with this ChangeRequest

Returns:

The type associated with this ChangeRequest

getOps

public int getOps()

Get the interestOps associated with this ChangeRequest

Returns:

The interestOps associated with this ChangeRequest. Return of this method is unspecified for ChangeRequests with types other than TYPE_OPS.
