Method Detail

wasOnMountCalled

public boolean wasOnMountCalled()

Returns:

Whether onMount has been called.

isMounted

public boolean isMounted()

Returns:

Whether the component is currently mounted.

wasOnUnmountCalled

public boolean wasOnUnmountCalled()

Returns:

Whether onUnmount has been called.

wasOnBoundsDefinedCalled

public boolean wasOnBoundsDefinedCalled()

Returns:

Whether onBoundsDefined has been called.

wasOnBindCalled

public boolean wasOnBindCalled()

Returns:

Whether onBind has been called.

isBound

public boolean isBound()

Returns:

Whether the component is bound.

wasOnUnbindCalled

public boolean wasOnUnbindCalled()

Returns:

Whether onUnbind has been called.

wasMeasureCalled

public boolean wasMeasureCalled()

wasOnAttachedCalled

public boolean wasOnAttachedCalled()

Returns:

Whether onAttached has been called.

wasOnDetachedCalled

public boolean wasOnDetachedCalled()

Returns:

Whether onDetached has been called.

hashCode

public int hashCode()

Overrides:

hashCode in class Object

equals

public boolean equals(Object o)

Overrides:

equals in class Object

isEquivalentTo

public boolean isEquivalentTo(Component other)

Description copied from class: Component

Compares this component to a different one to check if they are the same

This is used to be able to skip rendering a component again. We avoid using the Object.equals(Object) so we can optimize the code better over time since we don't have to adhere to the contract required for a equals method.

Specified by:

isEquivalentTo in interface Equivalence<Component>

Overrides:

isEquivalentTo in class Component

Parameters:

other - the component to compare to

Returns:

true if the components are of the same type and have the same props

resetInteractions

public void resetInteractions()

Reset the tracking of which methods have been called on this component.

dispatchOnEvent

public Object dispatchOnEvent(EventHandler eventHandler,
                              Object eventState)

Specified by:

dispatchOnEvent in interface EventDispatcher

Overrides:

dispatchOnEvent in class ComponentLifecycle

getDispatchedEventHandlers

public Set<EventHandler<?>> getDispatchedEventHandlers()

getEventState

public Object getEventState(EventHandler eventHandler)

isEquivalentToCalled

public boolean isEquivalentToCalled()
