Class HexBinaryValue

    • Constructor Detail

      • HexBinaryValue

        public HexBinaryValue​(java.lang.CharSequence in)
                       throws XPathException
        Constructor: create a hexBinary value from a supplied string, in which each octet is represented by a pair of values from 0-9, a-f, A-F
        Parameters:
        in - character representation of the hexBinary value
        Throws:
        XPathException
      • HexBinaryValue

        public HexBinaryValue​(java.lang.CharSequence s,
                              AtomicType type)
        Constructor: create a HexBinary value from a supplied string in hexBinary encoding, with a specified type. This method throws no checked exceptions; the caller is expected to ensure that the string is a valid Base64 lexical representation, that it conforms to the specified type, and that the type is indeed a subtype of xs:base64Binary. An unchecked exception such as an IllegalArgumentException may be thrown if these conditions are not satisfied, but this is not guaranteed.
        Parameters:
        s - the value in hexBinary encoding, with no leading or trailing whitespace
        type - the atomic type. This must be xs:base64binary or a subtype.
      • HexBinaryValue

        public HexBinaryValue​(byte[] value)
        Constructor: create a hexBinary value from a given array of bytes
        Parameters:
        value - the value as an array of bytes
    • Method Detail

      • copyAsSubType

        public AtomicValue copyAsSubType​(AtomicType typeLabel)
        Create a primitive copy of this atomic value (usually so that the type label can be changed).
        Specified by:
        copyAsSubType in class AtomicValue
        Parameters:
        typeLabel - the target type (a derived type from hexBinary)
        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
      • getBinaryValue

        public byte[] getBinaryValue()
        Get the binary value
        Returns:
        the binary value, as a byte array
      • convertPrimitive

        public ConversionResult convertPrimitive​(BuiltInAtomicType requiredType,
                                                 boolean validate,
                                                 XPathContext context)
        Convert to target data type
        Specified by:
        convertPrimitive in class AtomicValue
        Parameters:
        requiredType - an integer identifying the required atomic type
        context - XPath dynamic evaluation context
        validate - true if validation is required. If set to false, the caller guarantees that the value is valid for the target data type, and that further validation is therefore not required. Note that a validation failure may be reported even if validation was not requested.
        Returns:
        an AtomicValue, a value of the required type; or an ErrorValue
      • getLengthInOctets

        public int getLengthInOctets()
        Get the number of octets in the value
        Returns:
        the number of octets (bytes) in the value
      • getSchemaComparable

        public java.lang.Comparable getSchemaComparable()
        Support XML Schema comparison semantics
        Specified by:
        getSchemaComparable in class AtomicValue
        Returns:
        a Comparable that follows XML Schema comparison rules
      • getXPathComparable

        public java.lang.Object getXPathComparable​(boolean ordered,
                                                   StringCollator collator,
                                                   XPathContext context)
        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:
        getXPathComparable in class AtomicValue
        Parameters:
        ordered - true if an ordered comparison is required. In this case the result is null if the type is unordered; in other cases the returned value will be a Comparable.
        collator -
        context - the XPath dynamic evaluation context, used in cases where the comparison is context sensitive @return 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
        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
      • equals

        public boolean equals​(java.lang.Object other)
        Test if the two hexBinary or Base64Binaryvalues are equal.
        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
      • hashCode

        public int hashCode()
        Overrides:
        hashCode in class java.lang.Object
