Constructor Detail

NormalizedString

public NormalizedString(String string)

Creates a new NormalizedString instance. The specified string is normalized if it is not normalized already.

Parameters:

string - The normalized or non-normalized string.

Method Detail

normalize

public static String normalize(String string)

getValue

public String getValue()

Description copied from interface: INormalizedString

Returns the string representing this xsd:normalizedString.

Specified by:

getValue in interface INormalizedString

Specified by:

getValue in interface IStringTerm

Specified by:

getValue in interface ITerm

Returns:

The string representing this xsd:normalizedString.

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".

Specified by:

getDatatypeIRI in interface IConcreteTerm

Returns:

The fully qualified identifier for the data type corresponding to this term.

toCanonicalString

public String toCanonicalString()

Description copied from interface: IConcreteTerm

Returns a canonical string representation of this term.

Specified by:

toCanonicalString in interface IConcreteTerm

Returns:

A canonical string representation of this term.

toString

public String toString()

Overrides:

toString in class Object

isGround

public boolean isGround()

Description copied from interface: ITerm

Checks whether the term is ground (a term with no variables).

Specified by:

isGround in interface ITerm

Returns:

true if the term is ground, otherwise false.

compareTo

public int compareTo(ITerm o)

Specified by:

compareTo in interface Comparable<ITerm>

equals

public boolean equals(Object obj)

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object
