Constructor Details

LifecycledCallbackHandler

public LifecycledCallbackHandler(Lifecycled<T> lifecycled)

Method Details

onInvalidated

public <O> void onInvalidated(O owner,
 BiConsumer<O,? super Lifecycled<T>> callback)

Description copied from interface: Lifecycled.Events

Add a callback for when this lifecycled is invalidated. Will be called immediately if this lifecycled is currently invalid.

The callback should not reference the owner, it must only access it via the parameter. This ensures that the owner will be GC-able, otherwise it may be stuck in a reference loop.

Specified by:

onInvalidated in interface Lifecycled.Events<T>

Parameters:

owner - when the owner is GC'd, the callback is removed

callback - the callback, will be passed the lifecycled object

onNewValue

public <O> void onNewValue(O owner,
 BiConsumer<O,? super Lifecycled<T>> callback)

Description copied from interface: Lifecycled.Events

Add a callback for when this lifecycled is given a new value. Will be called immediately if this lifecycled is currently valid.

The callback should not reference the owner, it must only access it via the parameter. This ensures that the owner will be GC-able, otherwise it may be stuck in a reference loop.

Specified by:

onNewValue in interface Lifecycled.Events<T>

Parameters:

owner - when the owner is GC'd, the callback is removed

callback - the callback, will be passed the lifecycled object

fireInvalidated

public void fireInvalidated()

Fire onInvalidated(Object, BiConsumer) callbacks.

fireOnNewValue

public void fireOnNewValue()

Fire onNewValue(Object, BiConsumer) callbacks, the Lifecycled.value() must be available.
