Class IntValue

java.lang.Object

burlap.oomdp.core.values.OOMDPValue

burlap.oomdp.core.values.IntValue

All Implemented Interfaces:

Value

public class IntValue
extends OOMDPValue
implements Value

This class provides a value for an integer. The value may be negative or postive and exist in any range. This value object should be preferred for discrete values that span a large numeric range and for which it would be ineffecient to store an array of all possible values in the attribtue. Otherwise the DiscreteValue class should be preferred.

Constructor Detail

IntValue

public IntValue(Attribute attribute)

Initializes for a given attribute. The default value will be set to 0.

Parameters:

attribute -

IntValue

public IntValue(IntValue v)

Initializes from an existing IntUnBound value.

Parameters:

v - the value to copy

IntValue

public IntValue(Attribute attribute,
        int intVal)

Method Detail

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.

Specified by:

valueHasBeenSet in interface Value

Returns:

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

copy

public Value copy()

Description copied from interface: Value

Creates a deep copy of this value object.

Specified by:

copy in interface Value

Returns:

a deep copy of this value object.

setValue

public Value setValue(int v)

Description copied from class: OOMDPValue

Sets the internal value representation using an int value

Specified by:

setValue in interface Value

Overrides:

setValue in class OOMDPValue

Parameters:

v - the int value assignment

setValue

public Value setValue(double v)

Description copied from class: OOMDPValue

Sets the internal value representation using a double value

Specified by:

setValue in interface Value

Overrides:

setValue in class OOMDPValue

Parameters:

v - the double value assignment

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

setValue

public Value setValue(boolean v)

Description copied from class: OOMDPValue

Sets the internalvalue representation using a boolean value

Specified by:

setValue in interface Value

Overrides:

setValue in class OOMDPValue

Parameters:

v - the boolean value

getDiscVal

public int getDiscVal()

Description copied from class: OOMDPValue

Returns the discrete integer value of this Value object

Specified by:

getDiscVal in interface Value

Overrides:

getDiscVal in class OOMDPValue

Returns:

the discrete integer value of this Value object

buildStringVal

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

Specified by:

buildStringVal in interface Value

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.

equals

public boolean equals(java.lang.Object obj)

Overrides:

equals in class java.lang.Object

getBooleanValue

public boolean getBooleanValue()

Description copied from class: OOMDPValue

Returns the boolean value of this attibute. For int values, this means 0 = false and all other values = true.

Specified by:

getBooleanValue in interface Value

Overrides:

getBooleanValue in class OOMDPValue

Returns:

the boolean value of this attribute.
