Public methods

public static MotionScene.Transition buildTransition (MotionScene scene, 
                int transitionId, 
                int startConstraintSetId, 
                ConstraintSet startConstraintSet, 
                int endConstraintSetId, 
                ConstraintSet endConstraintSet)

Builder for a basic transition that transition from the startConstraintSet to the endConstraintSet.

Parameters
`scene`	`MotionScene`
`transitionId`	`int`: a unique id to represent the created transition
`startConstraintSetId`	`int`
`startConstraintSet`	`ConstraintSet`
`endConstraintSetId`	`int`
`endConstraintSet`	`ConstraintSet`

Returns
`MotionScene.Transition`

public static void validate (MotionLayout layout)

It validates if the motion layout is setup correctly or not. Use this for debugging purposes.

Parameters
`layout`	`MotionLayout`

Returns
`void`	true if layout has valid scene and transition.
