java.lang.Objectjavolution.xml.QName
public final class QName
This class represents unique identifiers for XML elements (tags) or attributes (names).
It should be noted that QName.valueOf(null, "name")
and
QName.valueOf("", "name")
are distinct; the first one has no
namespace associated with; whereas the second is associated
to the root namespace.
QName
have a textual representation (CharSequence
) which
is either the local name (if no namespace URI) or
{namespaceURI}localName
(otherwise).
Method Summary | |
---|---|
char |
charAt(int index)
Returns the character at the specified index. |
boolean |
equals(java.lang.Object obj)
Instances of this class are unique; object's equality can be replaced object identity ( == ). |
java.lang.CharSequence |
getLocalName()
Returns the local part of this qualified name or the full qualified name if there is no namespace. |
java.lang.CharSequence |
getNamespaceURI()
Returns the namespace URI of this qualified name or null
if none (the local name is then the full qualified name). |
int |
hashCode()
Returns the hash code for this qualified name. |
int |
length()
Returns the length of this character sequence. |
java.lang.CharSequence |
subSequence(int start,
int end)
Returns a new character sequence that is a subsequence of this sequence. |
java.lang.String |
toString()
Returns the String representation of this qualified name. |
static QName |
valueOf(java.lang.CharSequence name)
Returns the qualified name corresponding to the specified character sequence representation (may include the "{namespaceURI}" prefix). |
static QName |
valueOf(java.lang.CharSequence namespaceURI,
java.lang.CharSequence localName)
Returns the qualified name corresponding to the specified namespace URI and local name. |
static QName |
valueOf(java.lang.String name)
Equivalent to valueOf(CharSequence) (for J2ME compatibility). |
