    • Base64BinaryValue

      public Base64BinaryValue(CharSequence s) throws XPathException
      Constructor: create a base64Binary value from a supplied string in base64 encoding
      Parameters:
      s - the lexical representation of the base64 binary value. There is no requirement that whitespace should already be collapsed.
      Throws:
      XPathException
    • Base64BinaryValue

      public Base64BinaryValue(CharSequence s, AtomicType type)
      Constructor: create a base64Binary value from a supplied string in base64 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 base64 encoding
      type - the atomic type. This must be xs:base64binary or a subtype.
    • Base64BinaryValue

      public Base64BinaryValue(byte[] value)
      Constructor: create a base64Binary value from a given array of bytes
      Parameters:
      value - array of bytes holding the octet sequence
  • Method Details

    • copyAsSubType

      public AtomicValue copyAsSubType(AtomicType typeLabel)
      Create a copy of this atomic value (usually so that the type label can be changed). The type label of the copy will be reset to the primitive type.
      Specified by:
      copyAsSubType in class AtomicValue
      Parameters:
      typeLabel - the type label to be attached to the value, a subtype of xs:base64Binary
      Returns:
      the copied value
    • getBinaryValue

      public byte[] getBinaryValue()
      Get the binary value
      Returns:
      the octet sequence that is the typed value
    • getPrimitiveType

      public BuiltInAtomicType getPrimitiveType()
      Description copied from class: AtomicValue
      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 xs:anyAtomicType.
      Specified by:
      getPrimitiveType in class AtomicValue
      Returns:
      the primitive type
    • 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 - the 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
    • getStringValue

      public String getStringValue()
      Convert to string
      Specified by:
      getStringValue in interface Item
      Specified by:
      getStringValue in interface ValueRepresentation
      Specified by:
      getStringValue in class AtomicValue
      Returns:
      the canonical representation.
      See Also:
    • getLengthInOctets

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

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

      public 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(Object other)
      Test if the two base64Binary values 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 Object
    • byteArrayHashCode

      protected static int byteArrayHashCode(byte[] value)
