Method Detail

getInterpolatorCount

int getInterpolatorCount()

Get the number of interpolators supported.

makeInterpolator

Interpolator makeInterpolator(int interpolator)

Create an Interpolator of the given type.

getShortName

String getShortName(int interpolator)

Get the short name of an interpolator type.

getTypeFromName

int getTypeFromName(String name)

Get the interpolator type, given a short name. Returns -1 if the name isn't known.

getInterpolatorType

int getInterpolatorType(Interpolator interpolator)

Return the numeric type of a given Interpolator. Returns -1 if the type is unknown.
