public abstract class FunctionOperator
extends Operator

Superclass of functions that execute synchronously (blocking, in thread) and take N input parameters and one variable argument (as the final argument), generating a new task with the result of the function substituted in the variable's place.

Method Detail

function

protected abstract Term function(Memory memory,
                                 Term[] x)

y = function(x)

Returns:

y, or null if unsuccessful

getRange

@Deprecated
protected abstract Term getRange()

Deprecated.

the term that the output will inherit from; analogous to the 'Range' of a function in mathematical terminology

execute

protected List<Task> execute(Operation operation,
                             Term[] args,
                             Memory m,
                             Timable time)

Description copied from class: Operator

Required method for every operator, specifying the corresponding operation

Specified by:

execute in class Operator

args - Arguments of the operation, both input (constant) and output (variable)

m - The memory to work on

Returns:

The direct collectable results and feedback of the reportExecution

equals

public float equals(Term a,
                    Term b)

(can be overridden in subclasses) the extent to which it is truth that the 2 given terms are equal. in other words, a distance metric
