Constructor Detail

HexBinaryValue

public HexBinaryValue(UnicodeString 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 - if the input is invalid

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

getPrimitiveStringValue

public UnicodeString getPrimitiveStringValue()

Convert to string

Specified by:

getPrimitiveStringValue in class AtomicValue

Returns:

the canonical representation.

getLengthInOctets

public int getLengthInOctets()

Get the number of octets in the value

Returns:

the number of octets (bytes) in the value

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 - collation to be used for comparing strings

implicitTimezone - to be used for comparing dates/times with no timezone

Returns:

a key used for performing the comparison

getXPathComparable

public XPathComparable getXPathComparable(StringCollator collator,
                                          int implicitTimezone)

Description copied from class: AtomicValue

Get an object value that implements the XPath equality and ordering comparison semantics for this value. A collation is supplied for comparing strings, and an implicit timezone for comparing date/time values that have no saved timezone. An atomic value may return itself as the result, provided that its ordering rules are independent of the collation and timezone, and provided that it implements the XPathComparable interface: which means that its compareTo, equals, and hashCode methods must be compatible with the rules for XPath value comparisons.

Specified by:

getXPathComparable in class AtomicValue

Parameters:

collator - the collation to be used when comparing strings

implicitTimezone - the implicit timezone in the dynamic context, used when comparing dates/times with and without timezone

Returns:

an Object that implements the XPath value comparison semantics with respect to this atomic value. For an atomic type that is not ordered (according to XPath rules), return null.

getXPathComparable

public XPathComparable getXPathComparable()

Description copied from interface: ContextFreeAtomicValue

Get an XPathComparable object that supports the semantics of context-free eq and lt comparisons between atomic values. Note that in many cases the returned XPathComparable will be the AtomicValue itself; however because of the constraints of the generic Comparable interface, this cannot be assumed.

Specified by:

getXPathComparable in interface ContextFreeAtomicValue

Returns:

an XPathComparable that can be used in comparisons with other atomic values.

equals

public boolean equals(java.lang.Object other)

Test if the two hexBinary or Base64Binaryvalues are equal.

Overrides:

equals in class AtomicValue

Parameters:

other - the other value

Returns:

true (in a subclass) 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()

Description copied from class: AtomicValue

Returns a hash code value for the object.

Overrides:

hashCode in class AtomicValue

compareTo

public int compareTo(XPathComparable o)

Specified by:

compareTo in interface java.lang.Comparable<XPathComparable>
