public class StringAttribute
extends AttributeValue

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

Note that there is currently some confusion in the XACML specification about whether this datatype should be able to handle XML elements (ie, whether <AttributeValue DataType="...string"><foo/> </AttributeValue> is valid). Until that is clarified the strict definition of the string datatype is used in this code, which means that elements are not valid.

Since:
1.0

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 java.lang.String value
The actual String value that this object represents.

Constructor Detail

StringAttribute

public StringAttribute(java.lang.String value)
Creates a new StringAttribute that represents the String value supplied.

Method Detail

getInstance

public static StringAttribute getInstance(org.w3c.dom.Node root)
Returns a new StringAttribute that represents the xs:string at a particular DOM node.


getInstance

public static StringAttribute getInstance(java.lang.String value)
Returns a new StringAttribute that represents the xs:string value indicated by the String provided.


getValue

public java.lang.String getValue()
Returns the String value represented by this 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.


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.


toString

public java.lang.String toString()
Converts to 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.
