Field Detail

type

private java.net.URI type

AttributeValue

protected AttributeValue(java.net.URI type)

Constructor that takes the specific attribute type.

getType

public java.net.URI getType()

Returns the type of this attribute value. By default this always returns the type passed to the constructor.

Specified by:

getType in interface com.sun.xacml.cond.Evaluatable

evaluatesToBag

public final boolean evaluatesToBag()

Returns whether or not this value is actually a bag of values. This is a required interface from Evaluatable, but the more meaningful isBag method is used by AttributeValues, so this method is declared as final and calls the isBag method for this value.

Specified by:

evaluatesToBag in interface com.sun.xacml.cond.Evaluatable

getChildren

public java.util.List getChildren()

Always returns an empty list since values never have children.

Specified by:

getChildren in interface com.sun.xacml.cond.Evaluatable

isBag

public boolean isBag()

Returns whether or not this value is actually a bag of values. By default this returns false. Typically, only the BagAttribute should ever override this to return true.

evaluate

public com.sun.xacml.cond.EvaluationResult evaluate(com.sun.xacml.EvaluationCtx context)

Implements the required interface from Evaluatable. Since there is nothing to evaluate in an attribute value, the default result is just this instance. Override this method if you want special behavior, like a dynamic value.

Specified by:

evaluate in interface com.sun.xacml.cond.Evaluatable

encode

public abstract java.lang.String encode()

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.

encode

public void encode(java.io.OutputStream output)

Encodes this AttributeValue into its XML representation and writes this encoding to the given OutputStream with no indentation. This will always produce the version used in a policy rather than that used in a request, so this is equivalent to calling encodeWithTags(true) and then stuffing that into a stream.

Specified by:

encode in interface com.sun.xacml.cond.Evaluatable

encode

public void encode(java.io.OutputStream output,
                   com.sun.xacml.Indenter indenter)

Encodes this AttributeValue into its XML representation and writes this encoding to the given OutputStream with indentation. This will always produce the version used in a policy rather than that used in a request, so this is equivalent to calling encodeWithTags(true) and then stuffing that into a stream.

Specified by:

encode in interface com.sun.xacml.cond.Evaluatable

encodeWithTags

public java.lang.String encodeWithTags(boolean includeType)

Encodes the value and includes the AttributeValue XML tags so that the resulting string can be included in a valid XACML policy or Request/Response. The boolean parameter lets you include the DataType attribute, which is required in a policy but not allowed in a Request or Response.
