Constructor Detail

HexBinaryValue

public HexBinaryValue(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 - if the input is invalid

HexBinaryValue

public HexBinaryValue(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

getPrimitiveStringValue

public CharSequence 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

getSchemaComparable

public Comparable<net.sf.saxon.value.HexBinaryValue.HexBinaryComparable> getSchemaComparable()

Support XML Schema comparison semantics

Specified by:

getSchemaComparable in interface AtomicSequence

Specified by:

getSchemaComparable in class AtomicValue

Returns:

a Comparable that follows XML Schema comparison rules

getXPathComparable

public AtomicMatchKey getXPathComparable(boolean ordered,
                                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:

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 - 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

equals

public boolean equals(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 Object

compareTo

public int compareTo(Object o)

Specified by:

compareTo in interface Comparable
