Class ComponentAnimation.UIMutation

java.lang.Object

com.codename1.ui.animations.ComponentAnimation

com.codename1.ui.animations.ComponentAnimation.UIMutation

Enclosing class:

ComponentAnimation

public static class ComponentAnimation.UIMutation
extends ComponentAnimation

A special kind of ComponentAnimation that encapsulates a mutation of the user interface. This class used internally to allow compatible UI mutation animations to run concurrently. Two UI mutations are compatible if the containers that they mutate reside in separate branches of the UI tree. I.e. As long as neither container contains the other, their mutations are compatible.

Since:

7.0

Constructor Detail

UIMutation

public UIMutation(Container cnt,
                  ComponentAnimation anim)

Creates a new UIMutation which mutates the given container with the provided animation.

Parameters:

cnt - The container that is being mutated.

anim - The animation.

Method Detail

add

public boolean add(Container cnt,
                   ComponentAnimation anim)

Tries to add another mutation to this UIMutation.

Parameters:

cnt - The container that is being mutated.

anim - The animation

Returns:

True if it was successfully added. False otherwise. This will return false if isLocked() returns true (i.e. the animation has already stared), or if the mutation is incompatible with any of the existing mutations in this mutation.

isLocked

public boolean isLocked()

Checks if this mutation is locked. Once a mutation animation has started, it becomes locked, and cannot have any further mutations added to it.

Returns:

updateState

protected void updateState()

Description copied from class: ComponentAnimation

Updates the animation state

isInProgress

public boolean isInProgress()

Description copied from class: ComponentAnimation

Indicates if the animation is in progress

Specified by:

Returns:

true if in progress

flush

public void flush()

Description copied from class: ComponentAnimation

Flushes the animation immediately, this will be called if the form is de-initialized

getMaxSteps

public int getMaxSteps()

Description copied from class: ComponentAnimation
