类 IntArrayEstimator

java.lang.Object

ohos.agp.animation.util.IntArrayEstimator

所有已实现的接口:

TypeEstimator<int[]>

public class IntArrayEstimator
extends Object
implements TypeEstimator<int[]>

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

构造器详细资料

IntArrayEstimator

public IntArrayEstimator()

Create a IntArrayEstimator. Note that each time a new array of the int type is returned.

IntArrayEstimator(int[])

IntArrayEstimator

public IntArrayEstimator(int[] lastingArray)

Create a IntArrayEstimator 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 int[] estimate(float progress,
                      int[] startKeyValue,
                      int[] endKeyValue)

Interpolates the value at each index by the progress. If IntArrayEstimator(int[]) was used to construct this object, reuseArray will be returned, otherwise a new int[] will be returned.

指定者:

estimate 在接口中 TypeEstimator<int[]>

参数:

progress - The progress from the starting to the ending values

startKeyValue - The start value.

endKeyValue - The end value.

返回:

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