Method Detail

isAbsolute
public boolean isAbsolute()
Description copied from class:IRIx
An absolute URI is one with a URI scheme and without a fragment. The other components, host (authority), path, and query, are optional.absolute-URI = scheme ":" hier-part [ "?" query ]
Beware of the meaning :
http:abc
is an absolute URI - it has only a schema and a path without a root.Note that a URI can be both "not absolute" and "not relative", e.g.
http://example/path#fragment
.See IRIx.isReference() for testing whether a URI is suitable for use in RDF.

isRelative
public boolean isRelative()
Description copied from class:IRIx
A relative URI one without a scheme, and maybe without some of the other parts.Often it is just the path part.
See IRIx.isReference() for testing whether a URI is suitable for use in RDF.
Note that a URI can be both "not absolute" and "not relative", e.g.
http://example/path#fragment

isReference
public boolean isReference()
Description copied from class:IRIx
An RDF Reference is an URI which has scheme. If it is hierarchical, it should have a non-empty host authority. It may have a query component and may have a fragment component. This not a term in RFC 3986 and it is not the same as "absolute URI".In RDF data it is a useful concept. It is either an absolute URI, but if it is hierarchical, it must have a host.
Examples:
- http://www.w3.org/
- http://www.w3.org/1999/02/22-rdf-syntax-ns#type
- urn:abc:def
- urn:abc:def#frag
- http:abc -- no host authority; HTTP is a hierarchical URI scheme
- http:// -- the http(s) URI scheme requires the host to be not empty if there is an authority component.
In practical terms:
- It has a scheme name.
- It does not have user info ("user:password@")
- It can have a fragment.
- If it is an HTTP URI:
- It has a host authority, that is, a "//" section
- It should have a path (starting "/" after the host authority) but this is not required.
- If it is a URN (RFC8141), which is a "rootless URI" with no "//" part:
- Optionally, it can have a r-component (though this is not advised), a q-component, and a f-component (which is a URI fragment).

hasScheme
public boolean hasScheme(java.lang.String scheme)
Description copied from class:IRIx
Test whether the IRI has the given scheme name.The scheme name should be lowercase.
-
resolve
public IRIx resolve(java.lang.String other)
Description copied from class:IRIx
Try to resolve a string against this IRI as base. This call is "base.resolver(possibleRelativeIRI)". ThrowIRIException
if the string does not conform to the IRI grammar.
-
resolve
public IRIx resolve(IRIx other)
Description copied from class:IRIx
Try to resolve a string against this IRI as base. ThrowIRIException
if the string does not conform to the IRI grammar. Return the original IRIx if there is no change.
-
normalize
public IRIx normalize()
Description copied from class:IRIx
Syntax-based Normalization Normalize anIRIx
.
-
relativize
public IRIx relativize(IRIx other)
Description copied from class:IRIx
Return (if possible), an IRI that is relative to the base argument. If this IRI is a relative path, this is returned unchanged.The base ("this" object) must have a scheme, have no fragment and no query string. Only the path name is made relative.
If no relative IRI can be found, return null.

getImpl
public IRI getImpl()
Description copied from class:IRIx
Return the implementation object of the provider. The class of the object depends on the provider.
