Constructor Detail

Base64BinaryAttribute

public Base64BinaryAttribute(byte[] value)

Creates a new Base64BinaryAttribute that represents the byte [] value supplied.

Parameters:

value - the byte [] value to be represented

Method Detail

getInstance

public static Base64BinaryAttribute getInstance(Node root)
                                         throws ParsingException

Returns a new Base64BinaryAttribute that represents the xsi:base64Binary at a particular DOM node.

Parameters:

root - the Node that contains the desired value

Returns:

a new Base64BinaryAttribute representing the appropriate value

Throws:

ParsingException - if a parsing error occurs

getInstance

public static Base64BinaryAttribute getInstance(String value)
                                         throws ParsingException

Returns a new Base64BinaryAttribute that represents the xsi:base64Binary value indicated by the string provided.

Parameters:

value - a string representing the desired value

Returns:

a new Base64BinaryAttribute representing the desired value

Throws:

ParsingException - if a parsing error occurs

getValue

public byte[] getValue()

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

Returns:

the byte [] value

equals

public boolean equals(Object o)

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

Overrides:

equals in class Object

Parameters:

o - the object to compare

Returns:

true if this object and the input represent the same value

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.

Overrides:

hashCode in class Object

Returns:

the object's hashcode value

toString

public String toString()

Returns a String representation.

Overrides:

toString in class Object

Returns:

the String representation

encode

public 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:

encode in class AttributeValue

Returns:

a String form of the value
