public class InterpolationTable
extends LookupTable

An interpolationTable transforms A source float (or integer) by finding the first interpolationTableEntry with A sourceValue that is less than or equal to (subject to includeBoundary) the source value.

For example, an interpolation table can be used to map A raw numeric score onto an identifier representing A grade. It may also be used to implement numeric transformations such as those from A simple raw score to A value on A calibrated scale.

Specified by:

getLookupEntries in class LookupTable

Returns:

lookupTableEntry children

getInterpolationEntries

public java.util.List<InterpolationTableEntry> getInterpolationEntries()

Gets interpolationTableEntry children.

Returns:

interpolationTableEntry children
