Class NumericVariableFeatures

java.lang.Object

burlap.behavior.functionapproximation.dense.NumericVariableFeatures

All Implemented Interfaces:

DenseStateFeatures

public class NumericVariableFeatures
extends java.lang.Object
implements DenseStateFeatures

A DenseStateFeatures that iterates through all state variables in a state and places them into the returned double array. Note that the values for the state variable must return a Number value. Alternatively, you may only have a subset of the state variables be used by setting up a white list of the variables to use with the addToWhiteList(Object) method. If you do not add any variables to the white list, then it will be assumed that all variables should be used.
