Enum Constant Detail

CHILD_ADDED

public static final PathChildrenCacheEvent.Type CHILD_ADDED

A child was added to the path

CHILD_UPDATED

public static final PathChildrenCacheEvent.Type CHILD_UPDATED

A child's data was changed

CHILD_REMOVED

public static final PathChildrenCacheEvent.Type CHILD_REMOVED

A child was removed from the path

CONNECTION_SUSPENDED

public static final PathChildrenCacheEvent.Type CONNECTION_SUSPENDED

Called when the connection has changed to ConnectionState.SUSPENDED This is exposed so that users of the class can be notified of issues that *might* affect normal operation. The PathChildrenCache is written such that listeners are not expected to do anything special on this event, except for those people who want to cause some application-specific logic to fire when this occurs. While the connection is down, the PathChildrenCache will continue to have its state from before it lost the connection and after the connection is restored, the PathChildrenCache will emit normal child events for all of the adds, deletes and updates that happened during the time that it was disconnected.

CONNECTION_RECONNECTED

public static final PathChildrenCacheEvent.Type CONNECTION_RECONNECTED

Called when the connection has changed to ConnectionState.RECONNECTED This is exposed so that users of the class can be notified of issues that *might* affect normal operation. The PathChildrenCache is written such that listeners are not expected to do anything special on this event, except for those people who want to cause some application-specific logic to fire when this occurs. While the connection is down, the PathChildrenCache will continue to have its state from before it lost the connection and after the connection is restored, the PathChildrenCache will emit normal child events for all of the adds, deletes and updates that happened during the time that it was disconnected.

CONNECTION_LOST

public static final PathChildrenCacheEvent.Type CONNECTION_LOST

Called when the connection has changed to ConnectionState.LOST This is exposed so that users of the class can be notified of issues that *might* affect normal operation. The PathChildrenCache is written such that listeners are not expected to do anything special on this event, except for those people who want to cause some application-specific logic to fire when this occurs. While the connection is down, the PathChildrenCache will continue to have its state from before it lost the connection and after the connection is restored, the PathChildrenCache will emit normal child events for all of the adds, deletes and updates that happened during the time that it was disconnected.

INITIALIZED

public static final PathChildrenCacheEvent.Type INITIALIZED

Posted when PathChildrenCache.start(PathChildrenCache.StartMode) is called with PathChildrenCache.StartMode.POST_INITIALIZED_EVENT. This event signals that the initial cache has been populated.

Method Detail

values

public static PathChildrenCacheEvent.Type[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (PathChildrenCacheEvent.Type c : PathChildrenCacheEvent.Type.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static PathChildrenCacheEvent.Type valueOf(java.lang.String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

java.lang.IllegalArgumentException - if this enum type has no constant with the specified name

java.lang.NullPointerException - if the argument is null
