estimate

public Object estimate(float progress,
                       Object startKeyValue,
                       Object endKeyValue)

The return value of this function is the computed intermediate value, which represents the start and end values in four bytes of a 32-bit int. Linear nterpolation is performed separately, and the values are recombined as the return value.

指定者:

estimate 在接口中 TypeEstimator<Object>

参数:

progress - The progress from the starting to the ending values

startKeyValue - A 32-bit int value representing colors in the separate bytes of the parameter

endKeyValue - A 32-bit int value representing colors in the separate bytes of the parameter

返回:

the computed intermediate value.
