Class ExecuteAction
- java.lang.Object
-
- org.simpleframework.transport.reactor.ExecuteAction
-
- All Implemented Interfaces:
java.lang.Runnable
,Action
class ExecuteAction extends java.lang.Object implements Action
TheExecuteAction
object is represents an action that the distributor is to process. This contains the operation and the required I/O events as an integer bit mask as well as the selectable channel used to register for selection. In order to ensure that the action does not remain within the distributor for too long the action has an expiry time.

Constructor Detail

ExecuteAction
public ExecuteAction(Operation task, int require, long expiry)
Constructor for theEvent
object. The actions are used to encapsulate the task to execute and the operations to listen to when some action is to be performed.- Parameters:
task
- this is the task to be executed when it is readyrequire
- this is the required operations to listen to
-
-
Method Detail
-
run
public void run()
This is used to execute the operation for the action. This will be executed when the interested I/O event is ready for the associatedSelectableChannel
object. If the action expires before the interested I/O operation is ready this will not be executed, instead the operation is canceled.- Specified by:
run
in interfacejava.lang.Runnable
-
getExpiry
public long getExpiry()
This is used to get the expiry for the operation. The expiry represents some static time in the future when the action will expire if it does not become ready. This is used to cancel the operation so that it does not remain in the distributor.
-
getChannel
public java.nio.channels.SelectableChannel getChannel()
This is theSelectableChannel
which is used to determine if the operation should be executed. If the channel is ready for a given I/O event it can be run. For instance if the operation is used to perform some form of read operation it can be executed when ready to read data from the channel.- Specified by:
getChannel
in interfaceAction
- Returns:
- this returns the channel used to govern execution
-
getOperation
public Operation getOperation()
This is used to acquire theOperation
that is to be executed when the required operations are ready. It is the responsibility of the distributor to invoke the operation.- Specified by:
getOperation
in interfaceAction
- Returns:
- the operation to be executed when it is ready
-
getInterest
public int getInterest()
This returns the I/O operations that the action is interested in as an integer bit mask. When any of these operations are ready the distributor will execute the provided operation.- Specified by:
getInterest
in interfaceAction
- Returns:
- the integer bit mask of interested I/O operations
