Interface IRI

All Known Implementing Classes:

InternedIRI

public interface IRI

An Internationalized Resource Identifier (IRI). IRIs may contain characters from the Universal Character Set (Unicode/ISO 10646), including Chinese or Japanese kanji, Korean, Cyrillic characters, and so forth. It is defined by RFC 3987.

An IRI can be split into a namespace part and a local name part, which are derived from an IRI string by splitting it in two using the following algorithm:

• Split after the first occurrence of the '#' character,
• If this fails, split after the last occurrence of the '/' character,
• If this fails, split after the last occurrence of the ':' character.

The last step should never fail as every legal (full) IRI contains at least one ':' character to separate the scheme from the rest of the IRI. The implementation should check this upon object creation.

Method Summary

Modifier and Type	Method and Description
boolean	equals(java.lang.Object o) Compares this IRI to another object.
java.lang.String	getLocalName() Return the local name part of this IRI.
java.lang.String	getNamespace() Return the namespace part of this IRI.
int	hashCode() Computes the hash code of this IRI.

Method Detail

getNamespace

java.lang.String getNamespace()

Return the namespace part of this IRI. The namespace is defined as per the algorithm described in the class documentation.

Returns:

the namespace of this IRI

getLocalName

java.lang.String getLocalName()

Return the local name part of this IRI. The local name is defined as per the algorithm described in the class documentation.

Returns:

the local name of this IRI

equals

boolean equals(java.lang.Object o)

Compares this IRI to another object.

Overrides:

equals in class java.lang.Object

Parameters:

o - the object to compare this IRI to

Returns:

true, if the other object is an instance of IRI and their values are equal; false, otherwise

hashCode

int hashCode()

Computes the hash code of this IRI.

Overrides:

hashCode in class java.lang.Object

Returns:

a hash code for this IRI
