Method Detail

getInstance

public static XSDDouble getInstance()

asDataRange

public RestrictedDatatype<Double> asDataRange()

Description copied from interface: Datatype

Get the canonical data range for a datatype

Specified by:

asDataRange in interface Datatype<Double>

Returns:

a DataRange representation of the datatype value space

equals

public boolean equals(Object obj)

Overrides:

equals in class Object

getCanonicalRepresentation

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

Description copied from interface: Datatype

Get the canonical representation of a lexical form

Specified by:

getCanonicalRepresentation in interface Datatype<Double>

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.

Specified by:

getLiteral in interface Datatype<Double>

Parameters:

value - Element of the value space for some datatype

Returns:

The ATermAppl representation of value

getName

public aterm.ATermAppl getName()

Description copied from interface: Datatype

Get the datatype identifier

Specified by:

getName in interface Datatype<Double>

Returns:

ATermAppl of URI for datatype

getPrimitiveDatatype

public Datatype<?> getPrimitiveDatatype()

Description copied from interface: Datatype

Get the primitive datatype associated with this datatype.

Specified by:

getPrimitiveDatatype in interface Datatype<Double>

Returns:

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

getValue

public Double getValue(aterm.ATermAppl literal)
                throws InvalidLiteralException

Description copied from interface: Datatype

Get the Java object representation of a data value

Specified by:

getValue in interface Datatype<Double>

Parameters:

literal - the literal

Returns:

the Java object representation of the lexical form

Throws:

InvalidLiteralException

hashCode

public int hashCode()

Overrides:

hashCode in class Object

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.

Specified by:

isPrimitive in interface Datatype<Double>

Returns:

true if the datatype is primitive, false else
