java.lang.Object

ohos.agp.animation.util.FloatArrayEstimator

所有已实现的接口:

TypeEstimator<float[]>

public class FloatArrayEstimator
extends Object
implements TypeEstimator<float[]>

This class can be used to perform type interpolation between float[] values. Each index into the array is treated as a separate value to interpolate.

构造器详细资料

FloatArrayEstimator

public FloatArrayEstimator()

Create a FloatArrayEstimator. Note that each time a new array of the float type is returned.

FloatArrayEstimator

public FloatArrayEstimator(float[] lastingArray)

Create a FloatArrayEstimator that reuses lastingArray for every estimate() call.

参数:

lastingArray - The array to modify and return from estimate.

方法详细资料

estimate

public float[] estimate(float progress,
                        float[] startKeyValue,
                        float[] endKeyValue)

Interpolates the value at each index by the progress. If lastingArrayexists,it will be returned, otherwise a new float[] will be returned.

指定者:

estimate 在接口中 TypeEstimator<float[]>

参数:

progress - The progress from the starting to the ending values.

startKeyValue - The start value.

endKeyValue - The end value.

返回:

A float[] where each element is an interpolation between the same index in startKeyValue and endKeyValue.
