Method Detail

is_activated

public boolean is_activated()

Whether the LifeCycleMetaData has had any callbacks or listeners registered. Used for a quick test to determine whether to attempt to fire any events.

Returns:

boolean

getIgnoreSystemListeners

public boolean getIgnoreSystemListeners()

Whether to exclude system listeners from events.

setIgnoreSystemListeners

public void setIgnoreSystemListeners(boolean ignore)

Whether to exclude system listeners from events.

getIgnoreSuperclassCallbacks

public int getIgnoreSuperclassCallbacks()

Whether to exclude superclass callbacks from events.

setIgnoreSuperclassCallbacks

public void setIgnoreSuperclassCallbacks(int ignore)

Whether to exclude superclass callbacks from events.

getDeclaredCallbacks

public LifecycleCallbacks[] getDeclaredCallbacks(int eventType)

Return the declared callbacks for the given event type.

getCallbacks

public LifecycleCallbacks[] getCallbacks(int eventType)

Return all callbacks for the given event type, including superclass callbacks if appropriate.

setDeclaredCallbacks

public void setDeclaredCallbacks(int eventType,
                        LifecycleCallbacks[] callbacks,
                        int highPriority)

Set the callbacks for the given event type.

Parameters:

highPriority - the first N given callbacks are high priority; high priority callbacks will be returned before non-high-priority superclass callbacks

getNonPCSuperclassCallbacks

public LifecycleCallbacks[] getNonPCSuperclassCallbacks(int eventType)

Return the callbacks for the non-PC superclass.

setNonPCSuperclassCallbacks

public void setNonPCSuperclassCallbacks(int eventType,
                               LifecycleCallbacks[] callbacks,
                               int highPriority)

Set the callbacks for the given event type for non-persistent superclass. Note these callbacks will only be used where the non-persistent superclass is the direct ancestor of the described class.

Parameters:

highPriority - the first N given callbacks are high priority; high priority callbacks will be returned before non-high-priority superclass callbacks
