Class QNameValue

    • Constructor Detail

      • QNameValue

        public QNameValue​(java.lang.String prefix,
                  java.lang.String uri,
                  java.lang.String localName)
        Constructor for a QName that is known to be valid. No validation takes place.
        Parameters:
        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 QName

      • QNameValue

        public QNameValue​(java.lang.String prefix,
                  java.lang.String uri,
                  java.lang.String localName,
                  AtomicType type)
        Constructor for a QName that is known to be valid, allowing a user-defined subtype of QName to be specified. No validation takes place.
        Parameters:
        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 QName
        type - The type label, xs:QName or a subtype of xs:QName

      • QNameValue

        public QNameValue​(java.lang.String prefix,
                  java.lang.String uri,
                  java.lang.String localName,
                  AtomicType type,
                  boolean check)
           throws XPathException
        Constructor. This constructor validates that the local part is a valid NCName.
        Parameters:
        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 QName
        type - The atomic type, which must be either xs:QName, or a user-defined type derived from xs:QName by restriction
        check - Supply false if the name does not need to be checked (the caller asserts that it is known to be valid)
        Throws:
        XPathException - if the local part of the name is malformed or if the name has a null namespace with a non-empty prefix

      • QNameValue

        public QNameValue​(StructuredQName qName,
                  AtomicType typeLabel)
        Constructor
        Parameters:
        qName - the name as a StructuredQName
        typeLabel - idenfies a subtype of xs:QName

    • Method Detail

      • copyAsSubType

        public AtomicValue copyAsSubType​(AtomicType typeLabel)
        Create a copy of this atomic value, with a different type label
        Specified by:
        copyAsSubType in class AtomicValue
        Parameters:
        typeLabel - the type label of the new copy. The caller is responsible for checking that the value actually conforms to this type.
        Returns:
        the copied value

      • getPrimitiveType

        public BuiltInAtomicType getPrimitiveType()
        Determine the primitive type of the value. This delivers the same answer as getItemType().getPrimitiveItemType(). The primitive types are the 19 primitive types of XML Schema, plus xs:integer, xs:dayTimeDuration and xs:yearMonthDuration, and xs:untypedAtomic. For external objects, the result is AnyAtomicType.
        Specified by:
        getPrimitiveType in class AtomicValue
        Returns:
        the primitive type

      • getComponent

        public AtomicValue getComponent​(AccessorFn.Component part)
        Get a component. Returns a zero-length string if the namespace-uri component is requested and is not present.
        Overrides:
        getComponent in class AtomicValue
        Parameters:
        part - either Component.LOCALNAME or Component.NAMESPACE indicating which component of the value is required
        Returns:
        either the local name or the namespace URI, in each case as a StringValue

      • equals

        public boolean equals​(java.lang.Object other)
        Determine if two QName values are equal. This comparison ignores the prefix part of the value.
        Specified by:
        equals in class AtomicValue
        Parameters:
        other - the other value
        Returns:
        true if the other operand is an atomic value and the two values are equal as defined by the XPath eq operator
        Throws:
        java.lang.ClassCastException - if they are not comparable

      • getSchemaComparable

        public java.lang.Comparable getSchemaComparable()
        Description copied from class: AtomicValue
        Get a Comparable value that implements the XML Schema ordering comparison semantics for this value. An implementation must be provided for all atomic types.

        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 SequenceTool.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.

        Specified by:
        getSchemaComparable in interface AtomicSequence
        Specified by:
        getSchemaComparable in class AtomicValue
        Returns:
        a Comparable that follows XML Schema comparison rules
