makeQName

public static AtomicValue makeQName(java.lang.String prefix,
                                    java.lang.String uri,
                                    java.lang.String local,
                                    AtomicType targetType,
                                    UnicodeString lexicalForm,
                                    ConversionRules rules)
                             throws XPathException

Factory method to construct either a QName or a NOTATION value, or a subtype of either of these. Note that it is the caller's responsibility to resolve the QName prefix into a URI

Parameters:

prefix - the prefix part of the value. Use "" or null for the empty prefix.

uri - the namespace URI part of the value. Use "" or null for the non-namespace

local - the local part of the value

targetType - the target type, which must be xs:QName or a subtype of xs:NOTATION or xs:QName

lexicalForm - the original lexical form of the value. This is needed in case there are facets such as pattern that check the lexical form

rules - the conversion rules to be applied

Returns:

the converted value

Throws:

XPathException - if the value cannot be converted.

getPrimitiveStringValue

public final UnicodeString getPrimitiveStringValue()

Get the string value as a String. Returns the QName as a lexical QName, retaining the original prefix if available.

Specified by:

getPrimitiveStringValue in class AtomicValue

Returns:

the value converted to a string

getClarkName

public final java.lang.String getClarkName()

Get the QName in Clark notation, that is "{uri}local" if in a namespace, or "local" otherwise

Returns:

the name in Clark notation

getEQName

public final java.lang.String getEQName()

Get the QName in EQName notation, that is "Q{uri}local" if in a namespace, or "Q{}local" otherwise

Returns:

the name in EQName notation

getLocalName

public final java.lang.String getLocalName()

Get the local part

Returns:

the local part of the name (the part after the colon)

getNamespaceURI

public final java.lang.String getNamespaceURI()

Get the namespace part. Returns the empty string for a name in no namespace.

Returns:

the namespace URI component of the name, or "" for a no-namespace name

getPrefix

public final java.lang.String getPrefix()

Get the prefix. Returns the empty string if the name is unprefixed.

Returns:

the prefix, or "" to indicate no prefix

getXPathMatchKey

public AtomicMatchKey getXPathMatchKey(StringCollator collator,
                                       int implicitTimezone)

Get an object value that implements the XPath equality and ordering comparison semantics for this value. If the ordered parameter is set to true, the result will be a Comparable and will support a compareTo() method with the semantics of the XPath lt/gt operator, provided that the other operand is also obtained using the getXPathComparable() method. In all cases the result will support equals() and hashCode() methods that support the semantics of the XPath eq operator, again provided that the other operand is also obtained using the getXPathComparable() method. A context argument is supplied for use in cases where the comparison semantics are context-sensitive, for example where they depend on the implicit timezone or the default collation.

Specified by:

getXPathMatchKey in class AtomicValue

Parameters:

collator - the collation to be used for the comparison

implicitTimezone - the XPath dynamic evaluation context, used in cases where the comparison is context

Returns:

an Object whose equals() and hashCode() methods implement the XPath comparison semantics with respect to this atomic value. If ordered is specified, the result will either be null if no ordering is defined, or will be a Comparable

hashCode

public int hashCode()

Description copied from class: AtomicValue

Returns a hash code value for the object.

Overrides:

hashCode in class AtomicValue

isIdentical

public boolean isIdentical(AtomicValue v)

Description copied from class: AtomicValue

Determine whether two atomic values are identical, as determined by XML Schema rules. This is a stronger test than equality (even schema-equality); for example two dateTime values are not identical unless they are in the same timezone.

Note that even this check ignores the type annotation of the value. The integer 3 and the short 3 are considered identical, even though they are not fully interchangeable. "Identical" means the same point in the value space, regardless of type annotation.

NaN is identical to itself.

Overrides:

isIdentical in class AtomicValue

Parameters:

v - the other value to be compared with this one

Returns:

true if the two values are identical, false otherwise.

identityHashCode

public int identityHashCode()

Get a hashCode that offers the guarantee that if A.isIdentical(B), then A.identityHashCode() == B.identityHashCode()

Specified by:

identityHashCode in interface IdentityComparable

Overrides:

identityHashCode in class AtomicValue

Returns:

a hashCode suitable for use when testing for identity.

show

public java.lang.String show()

The show() method returns the name in the form QName("uri", "local")

Overrides:

show in class AtomicValue

Returns:

the name in in the form QName("uri", "local")

toJaxpQName

public javax.xml.namespace.QName toJaxpQName()

Construct a javax.xml.namespace.QName from this QualifiedNameValue

Returns:

an equivalent instance of the JAXP QName class

getStructuredQName

public StructuredQName getStructuredQName()

Get the equivalent StructuredQName

Returns:

the equivalent StructuredQName
