Class AbstractArrayFunction

java.lang.Object
  jas.statistics.functions.AbstractFunction
      jas.statistics.functions.AbstractArrayFunction

All Implemented Interfaces:

ISimEventListener, IUpdatableSource

Direct Known Subclasses:

CountArrayFunction, MaxArrayFunction, MeanArrayFunction, MeanVarianceArrayFunction, MinArrayFunction, MovingAverageArrayFunction, SumArrayFunction

public abstract class AbstractArrayFunction
extends AbstractFunction

This class represents the skeleton for all the function which opeate on array of native data type values. Each inheriting class automatically implements the IUpdatableSource and the ISimEventListener, which are managed by the AbstractArrayFunction.

Constructor Detail

AbstractArrayFunction

public AbstractArrayFunction(IDoubleArraySource source)

Create a function on a double array source.

Parameters:

source - The data source.

AbstractArrayFunction

public AbstractArrayFunction(IFloatArraySource source)

Create a function on a float array source.

Parameters:

source - The data source.

AbstractArrayFunction

public AbstractArrayFunction(IIntArraySource source)

Create a function on an integer array source.

Parameters:

source - The data source.

AbstractArrayFunction

public AbstractArrayFunction(ILongArraySource source)

Create a function on a long array source.

Parameters:

source - The data source.

Method Detail

apply

public void apply(double[] data)

Apply the function on a the given array of double values.

Parameters:

data - A source array of values.

Throws:

java.lang.UnsupportedOperationException - If the function is not able to work on double data type.

apply

public void apply(float[] data)

Apply the function on a the given array of float values.

Parameters:

data - A source array of values.

Throws:

java.lang.UnsupportedOperationException - If the function is not able to work on double data type.

apply

public void apply(int[] data)

Apply the function on a the given array of integer values.

Parameters:

data - A source array of values.

Throws:

java.lang.UnsupportedOperationException - If the function is not able to work on double data type.

apply

public void apply(long[] data)

Apply the function on a the given array of long values.

Parameters:

data - A source array of values.

Throws:

java.lang.UnsupportedOperationException - If the function is not able to work on double data type.

applyFunction

public void applyFunction()

Force the function to update itself. If the data source implements the IUpdatableSource interface it is updated before reading data.
