Class KeyValues<T>
java.lang.Object
org.pushingpixels.trident.interpolator.KeyValues<T>
Stores a list of values that correspond to the times in a
KeyTimes
object. These structures are then used to create a KeyFrames
object,
which is then used to create a TimelinePropertyBuilder.PropertySetter
for the purposes of
modifying an object's property over time.
At each of the times in KeyTimes
, the property will take on the
corresponding value in the KeyValues object. Between these times, the
property will take on a value based on the interpolation information stored
in the KeyFrames object and the PropertyInterpolator
for the type of the values
in KeyValues.
This class has built-in support for various known types, as defined in
PropertyInterpolator
.
For a simple example using KeyValues to create a KeyFrames and PropertySetter
object, see the class header comments in TimelinePropertyBuilder.PropertySetter
.

Method Details
-
create
Constructs a KeyValues object from one or more values. The internal Evaluator is automatically determined by the type of the parameters.- Parameters:
params
- the values to interpolate between. If there is only one parameter, this is assumed to be a "to" animation where the first value is dynamically determined at runtime when the animation is started.- Throws:
IllegalArgumentException
- if aPropertyInterpolator
cannot be found that can interpolate between the value types supplied
