public class HexBinaryAttribute

extends AttributeValue

Representation of an xsi:hexBinary value. This class supports parsing xsi:hexBinary values. All objects of this class are immutable and all methods of the class are thread-safe.

Since:

1.0

static java.lang.String	identifier           Official name of this type
private static java.net.URI	identifierURI           URI version of name for this type
private  java.lang.String	strValue           The value returned by toString().
private  byte[]	value           The actual binary value that this object represents.

 

Fields inherited from class com.sun.xacml.attr.AttributeValue

 

Constructor Summary

HexBinaryAttribute(byte[] value)           Creates a new HexBinaryAttribute that represents the byte [] value supplied.

 

Method Summary

java.lang.String	encode()           Encodes the value in a form suitable for including in XML data like a request or an obligation.
boolean	equals(java.lang.Object o)           Returns true if the input is an instance of this class and if its value equals the value contained in this class.
static HexBinaryAttribute	getInstance(org.w3c.dom.Node root)           Returns a new HexBinaryAttribute that represents the xsi:hexBinary at a particular DOM node.
static HexBinaryAttribute	getInstance(java.lang.String value)           Returns a new HexBinaryAttribute that represents the xsi:hexBinary value indicated by the string provided.
byte[]	getValue()           Returns the byte [] value represented by this object.
int	hashCode()           Returns the hashcode value used to index and compare this object with others of the same type.

Field Detail

identifier

public static final java.lang.String identifier

Official name of this type

Constant Field Values

---

identifierURI

private static java.net.URI identifierURI

URI version of name for this type

This field is initialized by a static initializer so that we can catch any exceptions thrown by URI(String) and transform them into a RuntimeException, since this should never happen but should be reported properly if it ever does.

---

earlyException

private static java.lang.RuntimeException earlyException

RuntimeException that wraps an Exception thrown during the creation of identifierURI, null if none.

---

value

private byte[] value

The actual binary value that this object represents.

---

strValue

private java.lang.String strValue

The value returned by toString(). Cached, but only generated if needed.

Constructor Detail

HexBinaryAttribute

public HexBinaryAttribute(byte[] value)

Creates a new HexBinaryAttribute that represents the byte [] value supplied.

Method Detail

getInstance

public static HexBinaryAttribute getInstance(org.w3c.dom.Node root)
                                      throws com.sun.xacml.ParsingException

Returns a new HexBinaryAttribute that represents the xsi:hexBinary at a particular DOM node.

---

getInstance

public static HexBinaryAttribute getInstance(java.lang.String value)
                                      throws com.sun.xacml.ParsingException

Returns a new HexBinaryAttribute that represents the xsi:hexBinary value indicated by the string provided.

---

getValue

public byte[] getValue()

Returns the byte [] value represented by this object. Note that this value is cloned before returning to prevent unauthorized modifications.

---

hashCode

public int hashCode()

Returns the hashcode value used to index and compare this object with others of the same type. Typically this is the hashcode of the backing data object.

---

equals

public boolean equals(java.lang.Object o)

Returns true if the input is an instance of this class and if its value equals the value contained in this class.

---

hexToBinNibble

private static int hexToBinNibble(char c)

Return the int value of a hex character. Return -1 if the character is not a valid hex character.

---

hexToBin

private static byte[] hexToBin(java.lang.String hex)

Parse a hex string, returning a new byte array containing the value. Return null in case of a parsing error.

---

binToHexNibble

private static char binToHexNibble(int nibble)

Return the hex character for a particular nibble (half a byte).

---

binToHex

private static java.lang.String binToHex(byte[] bytes)

Return a straight hexadecimal conversion of a byte array. This is a String containing only hex digits.

---

toString

public java.lang.String toString()

Returns a String representation.

---

encode

public java.lang.String encode()

Description copied from class: AttributeValue

Encodes the value in a form suitable for including in XML data like a request or an obligation. This must return a value that could in turn be used by the factory to create a new instance with the same value.

Specified by:
