Class IdleTimeoutFilter

java.lang.Object

org.glassfish.grizzly.filterchain.BaseFilter

org.glassfish.grizzly.utils.IdleTimeoutFilter

All Implemented Interfaces:

Filter

public class IdleTimeoutFilter
extends BaseFilter

The Filter is responsible for tracking Connection activity and closing Connection ones it becomes idle for certain amount of time. Unlike ActivityCheckFilter, this Filter assumes Connection is idle, when no event is being executed on it. But if some event processing was suspended - this Filter still assumes Connection is active.

Method Detail

handleAccept

public NextAction handleAccept(FilterChainContext ctx)
                        throws IOException

Description copied from class: BaseFilter

Execute a unit of processing work to be performed, when server channel has accepted the client connection. This Filter may either complete the required processing and return false, or delegate remaining processing to the next Filter in a FilterChain containing this Filter by returning true.

Specified by:

handleAccept in interface Filter

Overrides:

handleAccept in class BaseFilter

Parameters:

ctx - FilterChainContext

Returns:

NextAction instruction for FilterChain, how it should continue the execution

Throws:

IOException

handleConnect

public NextAction handleConnect(FilterChainContext ctx)
                         throws IOException

Description copied from class: BaseFilter

Execute a unit of processing work to be performed, when channel gets connected. This Filter may either complete the required processing and return false, or delegate remaining processing to the next Filter in a FilterChain containing this Filter by returning true.

Specified by:

handleConnect in interface Filter

Overrides:

handleConnect in class BaseFilter

Parameters:

ctx - FilterChainContext

Returns:

NextAction instruction for FilterChain, how it should continue the execution

Throws:

IOException

handleRead

public NextAction handleRead(FilterChainContext ctx)
                      throws IOException

Description copied from class: BaseFilter

Execute a unit of processing work to be performed, when channel will become available for reading. This Filter may either complete the required processing and return false, or delegate remaining processing to the next Filter in a FilterChain containing this Filter by returning true.

Specified by:

handleRead in interface Filter

Overrides:

handleRead in class BaseFilter

Parameters:

ctx - FilterChainContext

Returns:

NextAction instruction for FilterChain, how it should continue the execution

Throws:

IOException

handleWrite

public NextAction handleWrite(FilterChainContext ctx)
                       throws IOException

Description copied from class: BaseFilter

Execute a unit of processing work to be performed, when some data should be written on channel. This Filter may either complete the required processing and return false, or delegate remaining processing to the next Filter in a FilterChain containing this Filter by returning true.

Specified by:

handleWrite in interface Filter

Overrides:

handleWrite in class BaseFilter

Parameters:

ctx - FilterChainContext

Returns:

NextAction instruction for FilterChain, how it should continue the execution

Throws:

IOException

handleClose

public NextAction handleClose(FilterChainContext ctx)
                       throws IOException

Description copied from class: BaseFilter

Execute a unit of processing work to be performed, when connection has been closed. This Filter may either complete the required processing and return false, or delegate remaining processing to the next Filter in a FilterChain containing this Filter by returning true.

Specified by:

handleClose in interface Filter

Overrides:

handleClose in class BaseFilter
