public class Interpolator extends SequenceSource
Produce an interpolation based on the parameters. This class uses the Interpolation class in the math package to compute the interpolation. The values parameter specifies a sequence of values to produce at the output. The indexes parameter specifies when those values should be produced. The values and indexes parameters must both contain arrays, and have equal lengths or an exception will be thrown. The indexes array must be increasing and non-negative. The values are periodic if the period parameter contains a positive value. In this case, the period must be greater than the largest index, and values within the index range 0 to (period-1) are repeated indefinitely. If the period is zero, the values are not periodic, and the values outside the range of the indexes are considered to be 0.0. The order parameter specifies which order of interpolation to apply whenever the iteration count does not match an index in indexes. The Interpolation class currently supports zero, first, and third order interpolations. The default parameter are those set in the Interpolation class.
This actor counts iterations. Whenever the iteration count matches an entry in the indexes array, the corresponding entry (at the same position) in the values array is produced at the output. Whenever the iteration count does not match a value in the indexes array, an interpolation of the values is produced at the output.
Output type is DoubleToken.
