Method Detail

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.

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.

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

getRealVal

public double getRealVal()

Description copied from class: OOMDPValue

Returns the real-valued double value of this Value object

Specified by:

getRealVal in interface Value

Overrides:

getRealVal in class OOMDPValue

Returns:

the real-valued double 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.
