Class PrecomputedCDFunction

  • All Implemented Interfaces:
    java.io.Serializable , java.util.function.Function , jline.util.SerializableFunction 
    
public class PrecomputedCDFunction
 implements SerializableFunction<T, U>, Serializable

    A pre-computed class dependence function that stores function values for all possible state combinations.

    This class is used to convert MATLAB function handles to Java by pre-computing all possible function values in MATLAB and storing them in a lookup table. When the function is called in Java, it looks up the pre-computed value.

    The state is represented as a string key of the form "n1,n2,...,nR" where n_r is the number of jobs of class r at the station.
