Method Detail

getInstance

public static XSDDouble getInstance()

asDataRange

public RestrictedDatatype<java.lang.Double> asDataRange()

Description copied from interface: Datatype

Get the canonical _data range for a datatype

Returns:

a DataRange representation of the datatype value space

getCanonicalRepresentation

public openllet.aterm.ATermAppl getCanonicalRepresentation(openllet.aterm.ATermAppl input)
                                                    throws InvalidLiteralException

Description copied from interface: Datatype

Get the canonical representation of a lexical form

Parameters:

input - a lexical form of the literal

Returns:

the canonical representation of the lexical form

Throws:

InvalidLiteralException - if input is invalid

getLiteral

public openllet.aterm.ATermAppl getLiteral(java.lang.Object value)

Description copied from interface: Datatype

Get the canonical ATermAppl literal representation for a value space object. This may be unsupported by datatypes for which Datatype.isPrimitive() returns false.

Parameters:

value - Element of the value space for some datatype

Returns:

The ATermAppl representation of value

getPrimitiveDatatype

public Datatype<?> getPrimitiveDatatype()

Description copied from interface: Datatype

Get the primitive datatype associated with this datatype.

Returns:

this if isPrimitive() == true, else a primitive datatype that is a superset of the value space of this datatype.

getValue

public java.lang.Double getValue(openllet.aterm.ATermAppl literal)
                          throws InvalidLiteralException

Description copied from interface: Datatype

Get the Java object representation of a _data value

Parameters:

literal - the literal

Returns:

the Java object representation of the lexical form

Throws:

InvalidLiteralException - if literal is invalid

isPrimitive

public boolean isPrimitive()

Description copied from interface: Datatype

Check if a datatype is primitive. All datatypes are either primitive or derived. Derived datatypes are names for subsets of the value spaces of primitive datatypes, defined using specific constraining facet values.

Returns:

true if the datatype is primitive, false else
