public class QNameValue
A QName value. This implements the so-called "triples proposal", in which the prefix is retained as part of the value. The prefix is not used in any operation on a QName other than conversion of the QName to a string.

public QNameValue(String prefix, String uri, String localName)
prefix
- The prefix part of the QName (not used in comparisons). Use "" to represent the
default prefix.uri
- The namespace part of the QName. Use "" to represent the non-namespace.localName
- The local part of the QNamepublic QNameValue(String prefix, String uri, String localName, AtomicType type)
prefix
- The prefix part of the QName (not used in comparisons). Use "" to represent the
default prefix (but null is also accepted)uri
- The namespace part of the QName. Use null to represent the non-namespace (but "" is also
accepted).localName
- The local part of the QNametype
- The type label, xs:QName or a subtype of xs:QNamepublic QNameValue(NamePool namePool, int nameCode)
namePool
- The name pool containing the specified name codenameCode
- The name code identifying this name in the name poolpublic QNameValue(String prefix, String uri, String localName, AtomicType type, NameChecker checker) throws XPathException
prefix
- The prefix part of the QName (not used in comparisons). Use "" to represent the
default prefix (but null is also accepted).
Note that the prefix is not checked for lexical correctness, because in most cases
it will already have been matched against in-scope namespaces. Where necessary the caller must
check the prefix.uri
- The namespace part of the QName. Use null to represent the non-namespace (but "" is also
accepted).localName
- The local part of the QNametype
- The atomic type, which must be either xs:QName, or a
user-defined type derived from xs:QName by restrictionchecker
- NameChecker used to check the name against XML 1.0 or XML 1.1 rules. Supply null
if the name does not need to be checked (the caller asserts that it is known to be valid)
XPathException
- if the local part of the name is malformed or if the name has a null
namespace with a non-empty prefixpublic QNameValue(StructuredQName qName, AtomicType typeLabel)
qName
- the name as a StructuredQNametypeLabel
- idenfies a subtype of xs:QNameMethod Detail |

copyAsSubType
in class AtomicValue
typeLabel
- the type label of the new copy. The caller is responsible for checking that
the value actually conforms to this type.

getComponent
in class AtomicValue
part
- either Component.LOCALNAME or Component.NAMESPACE indicating which
component of the value is required
public boolean equals(Object other)

other
- the other value
ClassCastException
- if they are not comparablepublic Comparable getSchemaComparable()
AtomicValue
In the case of data types that are partially ordered, the returned Comparable extends the standard
semantics of the compareTo() method by returning the value Value.INDETERMINATE_ORDERING
when there
is no defined order relationship between two given values. This value is also returned when two values
of different types are compared.
