    • 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.

      Beware that RFC 2396 section 3.1 has a different definition, where the scheme is required but a fragment may be present.

      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 is 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". This is a change from RFC 2396 where an absolute URI means "has scheme".

      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
      but not
      • 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:

    • hasScheme

      public boolean hasScheme(String scheme)
      Description copied from class: IRIx
      Test whether the IRI has the given scheme name.

      The scheme name should be lowercase.

      Specified by:
      hasScheme in class IRIx

    • scheme

      public String scheme()
      Description copied from class: IRIx
      Return the IRI scheme, if known.

      Returns null for "no scheme" (relative IRI).

      Specified by:
      scheme in class IRIx

    • resolve

      public IRIx resolve(String other)
      Description copied from class: IRIx
      Try to resolve a string against this IRI as base. This call is "base.resolver(possibleRelativeIRI)". Throw IRIException if the string does not conform to the IRI grammar.
      Specified by:
      resolve in class IRIx

    • resolve

      public IRIx resolve(IRIx other)
      Description copied from class: IRIx
      Try to resolve a string against this IRI as base. Throw IRIException if the string does not conform to the IRI grammar. Return the original IRIx if there is no change.
      Specified by:
      resolve in class IRIx

    • normalize

      public IRIx normalize()
      Description copied from class: IRIx
      Syntax-based Normalization Normalize an IRIx.
      Specified by:
      normalize in class IRIx

    • 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.

      relativize in class IRIx

    • getImpl

      public IRI3986 getImpl()
      Description copied from class: IRIx
      Return the implementation object of the provider. The class of the object depends on the provider.
      Specified by:
      getImpl in class IRIx

    • hasViolations

      public boolean hasViolations()
      Return true if there are no "ignore items".

    • handleViolations

      public void handleViolations(BiConsumer<Boolean,String> handler)
      Description copied from class: IRIx
      Handle violations by sending a boolean, indicating whether this is an error (true) or a warning (false), and string message to a handler.
