Method Detail

accumulate

public boolean accumulate(float[] values)
                   throws VisADException

Accumulates a set of floats. Indicates whether or not the sequence is consistent with the arithmetic progression so far.

Overrides:

accumulate in class ArithProg

Parameters:

values - The values to accumulate.

Returns:

False if the difference between any current and previous value normalized by the current increment differs from unity by more than the nearness threshold; otherwise, true.

Throws:

VisADException - ArithProg.isConsistent() was false before this method was invoked.

accumulate

public boolean accumulate(double[] values)
                   throws VisADException

Accumulates a set of doubles. Indicates whether or not the sequence is consistent with the arithmetic progression so far.

Overrides:

accumulate in class ArithProg

Parameters:

values - The values to accumulate.

Returns:

False if the difference between any current and previous value normalized by the current increment differs from unity by more than the nearness threshold; otherwise, true.

Throws:

VisADException - ArithProg.isConsistent() was false before this method was invoked.

main

public static void main(java.lang.String[] args)
                 throws java.lang.Exception

Tests this class.

Parameters:

args - Runtime arguments. Ignored.

Throws:

java.lang.Exception - Something went wrong.
