getDefaultMaxSessionIdleTimeout

public long getDefaultMaxSessionIdleTimeout()

Description copied from interface: javax.websocket.WebSocketContainer

Get the current default session idle timeout.

Specified by:

getDefaultMaxSessionIdleTimeout in interface WebSocketContainer

Returns:

The current default session idle timeout in milliseconds. Zero or negative values indicate an infinite timeout.

setDefaultMaxSessionIdleTimeout

public void setDefaultMaxSessionIdleTimeout(long timeout)

Description copied from interface: javax.websocket.WebSocketContainer

Set the default session idle timeout.

Specified by:

setDefaultMaxSessionIdleTimeout in interface WebSocketContainer

Parameters:

timeout - The new default session idle timeout in milliseconds. Zero or negative values indicate an infinite timeout.

Description copied from interface: javax.websocket.WebSocketContainer

Get the default maximum buffer size for binary messages.

Specified by:

getDefaultMaxBinaryMessageBufferSize in interface WebSocketContainer

Returns:

The current default maximum buffer size in bytes

setDefaultMaxBinaryMessageBufferSize

public void setDefaultMaxBinaryMessageBufferSize(int max)

Description copied from interface: javax.websocket.WebSocketContainer

Set the default maximum buffer size for binary messages.

Specified by:

setDefaultMaxBinaryMessageBufferSize in interface WebSocketContainer

Parameters:

max - The new default maximum buffer size in bytes

getDefaultMaxTextMessageBufferSize

public int getDefaultMaxTextMessageBufferSize()

Description copied from interface: javax.websocket.WebSocketContainer

getInstalledExtensions

public Set<Extension> getInstalledExtensions()

Get the installed extensions. Currently, this implementation does not support any extensions.

Specified by:

getInstalledExtensions in interface WebSocketContainer

Returns:

The set of extensions that are supported by this WebSocket implementation.

getDefaultAsyncSendTimeout

public long getDefaultAsyncSendTimeout()

Get the default timeout for sending a message asynchronously. The default value for this implementation is -1.

backgroundProcess in interface BackgroundProcess

setProcessPeriod

public void setProcessPeriod(int period)

Specified by:

setProcessPeriod in interface BackgroundProcess

getProcessPeriod

public int getProcessPeriod()
