Class DoubleArrayValue

java.lang.Object

burlap.oomdp.core.values.OOMDPValue

burlap.oomdp.core.values.DoubleArrayValue

All Implemented Interfaces:

Value

public class DoubleArrayValue
extends OOMDPValue

This class implements an attribute value that is defined with a double array. In general, it is reccomended that a series of RealValue attributes is defined instead of using this class, because the series of individual RealValues will have better compatibility with existing BURLAP tools and algorithms, but this value can be used in cases where there is a very large number of double values that have to be stored in each state to cut down on memory overhead.

Method Detail

copy

public Value copy()

Description copied from interface: Value

Creates a deep copy of this value object.

Returns:

a deep copy of this value object.

valueHasBeenSet

public boolean valueHasBeenSet()

Description copied from interface: Value

Returns whether the value has been set to a meaningful value. Unset values typically happen when a new object instance has been created by not had its values set. Leaving values unset will result in exceptions being thrown to prevent errors in underspecified states.

Returns:

true if the value has been set; false if not.

setValue

public Value setValue(java.lang.String v)

Description copied from class: OOMDPValue

Sets the internal value representation using a string value

Specified by:

setValue in interface Value

Overrides:

setValue in class OOMDPValue

Parameters:

v - the string value assignment

buildStringVal

public java.lang.StringBuilder buildStringVal(java.lang.StringBuilder builder)

getNumericRepresentation

public double getNumericRepresentation()

Description copied from class: OOMDPValue

Returns a numeric representation

Specified by:

getNumericRepresentation in interface Value

Overrides:

getNumericRepresentation in class OOMDPValue

Returns:

a double value.

setValue

public Value setValue(int[] intArray)

Description copied from class: OOMDPValue

Sets the int array value.

Specified by:

setValue in interface Value

Overrides:

setValue in class OOMDPValue

Parameters:

intArray - the int array value to set.

setValue

public Value setValue(double[] doubleArray)

Description copied from class: OOMDPValue

Sets the double array value.

Specified by:

setValue in interface Value

Overrides:

setValue in class OOMDPValue

Parameters:

doubleArray - the double array value to set.

getIntArray

public int[] getIntArray()

Description copied from class: OOMDPValue

Returns an int array value

Specified by:

getIntArray in interface Value

Overrides:

getIntArray in class OOMDPValue

Returns:

an int array value

getDoubleArray

public double[] getDoubleArray()

Description copied from class: OOMDPValue

Returns a double array value

Specified by:

getDoubleArray in interface Value

Overrides:

getDoubleArray in class OOMDPValue

Returns:

a double array value.
