getValue

public BigDecimal getValue()

Description copied from interface: INumericTerm

Returns the value of this numeric term represented as a BigDecimal.

Specified by:

getValue in interface INumericTerm

Specified by:

getValue in interface ITerm

Returns:

The BigDecimal representing the value of this numeric term, or null if this term represents "NaN", positive infinity or negative infinity.

getDatatypeIRI

public URI getDatatypeIRI()

Description copied from interface: IConcreteTerm

Returns the fully qualified identifier for the data type corresponding to this term. For instance, a terms representing a double data type should return the URI "http://www.w3.org/2001/XMLSchema#double".

isNotANumber in interface INumericTerm

Returns:

true if this numeric term represents a "NaN" value, false otherwise

isPositiveInfinity

public boolean isPositiveInfinity()

Description copied from interface: INumericTerm

Returns true if this numeric term represents positive infinity, false otherwise.

Specified by:

true if this numeric term represents positive infinity, false otherwise.

isNegativeInfinity

public boolean isNegativeInfinity()

Description copied from interface: INumericTerm

Returns true if this numeric term represents negative infinity, false otherwise.

Specified by:

isNegativeInfinity in interface INumericTerm

Returns:

true if this numeric term represents negative infinity, false otherwise.
