Constructor Detail

URIImpl

public URIImpl(String uri)

Creates a new URI from the supplied string.

Parameters:

uri - A String representing a legal, absolute URI.

Throws:

IllegalArgumentException - If the supplied URI is not a legal (absolute) URI.

URIImpl

public URIImpl(String namespace,
               String localName)

Creates a new URI that will get the supplied namespace and local name.

Parameters:

namespace - A namespace.

localName - A legal local name. A legal local name adheres to the definition of an NCName as specified at http://www.w3.org/TR/REC-xml-names/#NT-NCName.

Method Detail

getNamespace

public String getNamespace()

Description copied from interface: URI

Gets the namespace of this URI.

Specified by:

getNamespace in interface URI

Returns:

The URI's namespace.

getLocalName

public String getLocalName()

Description copied from interface: URI

Gets the local name of this URI.

Specified by:

getLocalName in interface URI

Returns:

The URI's local name.

getURI

public String getURI()

Description copied from interface: URI

Returns the String-representation of this URI. The String-representation consists of the concatenation of the namespace and the local name.

Specified by:

getURI in interface URI

Returns:

The String-representation of this URI.

equals

public boolean equals(Object o)

Description copied from interface: URI

Compares a URI object to another object.

Specified by:

equals in interface URI

hashCode

public int hashCode()

Description copied from interface: URI

The hash code of a URI is defined as follows:

 namespace.hashCode() ^ localName.hashCode()
 

Specified by:

hashCode in interface URI

compareTo

public int compareTo(Object o)

Compares this URI with the supplied object.

Specified by:

compareTo in interface Comparable

Throws:

ClassCastException - if o is not of type Value

Comparable

toString

public String toString()

Returns the String-representation of this URI.
