Method Detail

getInstance

public static RDFPlainLiteral getInstance()

asDataRange

public RestrictedDatatype<aterm.ATermAppl> 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 aterm.ATermAppl getCanonicalRepresentation(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

getLiteral

public aterm.ATermAppl getLiteral(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 aterm.ATermAppl getValue(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

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
