Field Summary

static String

identifier Official name of this type

Constructor Summary

IntegerAttribute(long value)
Creates a new IntegerAttribute that represents the long value supplied.

Method Summary

String	encode() Encodes the value in a form suitable for including in XML data like a request or an obligation.
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.
static IntegerAttribute	getInstance(Node root) Returns a new IntegerAttribute that represents the xs:integer at a particular DOM node.
static IntegerAttribute	getInstance(String value) Returns a new IntegerAttribute that represents the xs:integer value indicated by the string provided.
long	getValue() Returns the long value represented by this object.
int	hashCode() Returns the hashcode value used to index and compare this object with others of the same type.

Constructor Detail

IntegerAttribute

public IntegerAttribute(long value)

Creates a new IntegerAttribute that represents the long value supplied.

Parameters:

value - the long value to be represented

Method Detail

getInstance

public static IntegerAttribute getInstance(Node root)
                                    throws NumberFormatException

Returns a new IntegerAttribute that represents the xs:integer at a particular DOM node.

Parameters:

root - the Node that contains the desired value

Returns:

a new IntegerAttribute representing the appropriate value (null if there is a parsing error)

Throws:

NumberFormatException - if the string form isn't a number

getInstance

public static IntegerAttribute getInstance(String value)
                                    throws NumberFormatException

Returns a new IntegerAttribute that represents the xs:integer value indicated by the string provided.

Parameters:

value - a string representing the desired value

Returns:

a new IntegerAttribute representing the appropriate value (null if there is a parsing error)

Throws:

NumberFormatException - if the string isn't a number

getValue

public long getValue()

Returns the long value represented by this object.

Returns:

the long 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.

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.

Returns:

the object's hashcode value

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
