URIReference

protected URIReference(String uri)

Method Detail

toString

public String toString()

Overrides:

toString in class Object

isAnonymous

public boolean isAnonymous()

Description copied from interface: AResource

True if this resource does not have an associated URI.

Specified by:

isAnonymous in interface AResource

Returns:

True if this resource is anonymous.

getAnonymousID

public String getAnonymousID()

Description copied from interface: AResource

A string distinguishing this anonymous resource, from other anonymous resources. Undefined if AResource.isAnonymous() returns false.

Specified by:

getAnonymousID in interface AResource

Returns:

An identifier with file scope for this anonymous resource..

getURI

public String getURI()

Description copied from interface: AResource

The URI reference for this resource, if any. Not defined if AResource.isAnonymous() returns true.

Specified by:

getURI in interface AResource

Returns:

The URI reference of this resource.

getUserData

public Object getUserData()

Description copied from interface: AResource

The user data allows the RDF application to store one Object with each blank node during parsing. This may help with garbage collect strategies when parsing huge files. No references to the user data are maintained after a blank node goes out of scope.

Specified by:

getUserData in interface AResource

Returns:

A user data object previously stored with AResource.setUserData(java.lang.Object); or null if none.

setUserData

public void setUserData(Object d)

Description copied from interface: AResource

The user data allows the RDF application to store one Object with each blank node during parsing. This may help with garbage collect strategies when parsing huge files. No references to the user data are maintained after a blank node goes out of scope.

See note about large files in class documentation for ARP.

Specified by:

setUserData in interface AResource

Parameters:

d - A user data object which may be retrieved later with AResource.getUserData().

equals

public boolean equals(Object o)

Does not compare userData field, only URI.

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object

hasNodeID

public boolean hasNodeID()

Description copied from interface: AResource

True, if this is an anonymous resource with an explicit rdf:nodeID.

Specified by:

hasNodeID in interface AResource

Returns:

true if this resource has a nodeID

setHasBeenUsed

public void setHasBeenUsed()

Description copied from interface: AResourceInternal

Only for blank nodes - non blank need not support.

Specified by:

setHasBeenUsed in interface AResourceInternal

getHasBeenUsed

public boolean getHasBeenUsed()

Description copied from interface: AResourceInternal

Only for blank nodes - non blank need not support.

Specified by:

getHasBeenUsed in interface AResourceInternal

fromID

public static URIReference fromID(Frame f,
                                  AbsXMLContext x,
                                  String name)
                           throws SAXParseException

Parameters:

f - A frame for error reporting. AbsXMLContext of frame is ignored.

x - The XML context for the base URI

name - The local name

Returns:

The resulting URI

Throws:

SAXParseException

resolve

public static URIReference resolve(Frame f,
                                   AbsXMLContext ctxt,
                                   String uri)
                            throws SAXParseException

Parameters:

f - A frame for error reporting. AbsXMLContext of frame is ignored.

ctxt - The XML context for the base URI

uri - Input string, may be relative etc.

Returns:

The resolved URI

Throws:

SAXParseException

fromQName

public static URIReference fromQName(Frame f,
                                     String ns,
                                     String local)
                              throws SAXParseException

Throws:

SAXParseException

createNoChecks
