TransitionValues
open class TransitionValues
Data structure which holds cached values for the transition. The view field is the target which all of the values pertain to. The values field is a map which holds information for fields according to names selected by the transitions. These names should be unique to avoid clobbering values stored by other transitions, such as the convention project:transition_name:property_name. For example, the platform might store a property "alpha" in a transition "Fader" as "android:fader:alpha".
These values are cached during the Transition.captureStartValues(TransitionValues) capture} phases of a scene change, once when the start values are captured and again when the end values are captured. These start/end values are then passed into the transitions via the for Transition.createAnimator(ViewGroup, TransitionValues, TransitionValues) method.

Public methods
equals
open fun equals(other: Any?): Boolean
Indicates whether some other object is "equal to" this one.
The equals method implements an equivalence relation on non-null object references:
- It is reflexive: for any non-null reference value
x, x.equals(x) should return true.
- It is symmetric: for any non-null reference values
x and y, x.equals(y) should return true if and only if y.equals(x) returns true.
- It is transitive: for any non-null reference values
x, y, and z, if x.equals(y) returns true and y.equals(z) returns true, then x.equals(z) should return true.
- It is consistent: for any non-null reference values
x and y, multiple invocations of x.equals(y) consistently return true or consistently return false, provided no information used in equals comparisons on the objects is modified.
- For any non-null reference value
x, x.equals(null) should return false.
An equivalence relation partitions the elements it operates on into equivalence classes; all the members of an equivalence class are equal to each other. Members of an equivalence class are substitutable for each other, at least for some purposes.
| Parameters |
obj |
the reference object with which to compare. |
other |
Any?: This value may be null. |
| Return |
Boolean |
true if this object is the same as the obj argument; false otherwise. |
hashCode
open fun hashCode(): Int
| Return |
Int |
a hash code value for this object. |
toString
open fun toString(): String
| Return |
String |
a string representation of the object. |
