Constructor Detail

SubjectImpl

public SubjectImpl()

Default constructor

SubjectImpl

public SubjectImpl(String xml)
            throws XACMLException

This constructor is used to build Subject object from a XML string.

Parameters:

xml - A java.lang.String representing a Subject object

Throws:

XACMLException - if it could not process the XML string

SubjectImpl

public SubjectImpl(Element element)
            throws XACMLException

This constructor is used to build Subject object from a block of existing XML that has already been built into a DOM.

Parameters:

element - A org.w3c.dom.Element representing DOM tree for Subject object

Throws:

XACMLException - if it could not process the Element

Method Detail

getAttributes

public List getAttributes()

Returns zero to many Attribute elements of this object If no attributes and present, empty List will be returned. Typically a Subject element will contain an Attribute with an AttributeId of "urn:oasis:names:tc:xacml:1.0:subject:subject-id", containing the identity of the Subject

Specified by:

getAttributes in interface Subject

Returns:

the Attribute elements of this object

setAttributes

public void setAttributes(List attributes)
                   throws XACMLException

Sets the Attribute elements of this object

Specified by:

setAttributes in interface Subject

Parameters:

attributes - Attribute elements of this object attributes could be an empty List, if no attributes are present.

Throws:

XACMLException - if the object is immutable An object is considered immutable if makeImmutable() has been invoked on it. It can be determined by calling isMutable on the object.

getSubjectCategory

public URI getSubjectCategory()

Returns the SubjectCategory of this object. This is optional so could be null if not defined. This attribute indicates the role that the parent Subject played in the formation of the access request. If this attribute is not present in the Subject element, then the default value of urn:oasis:names:tc:xacml:1.0:subject-category:access-subject SHALL be used, indicating that the Subject represents the entity ultimately responsible for initiating the access request.

Specified by:

getSubjectCategory in interface Subject

Returns:

URI representing the SubjectCategory of this object.

setSubjectCategory

public void setSubjectCategory(URI subjectCategory)
                        throws XACMLException

Sets the SubjectCategory of this object

Specified by:

setSubjectCategory in interface Subject

Parameters:

subjectCategory - URI

Throws:

XACMLException - if the object is immutable An object is considered immutable if makeImmutable() has been invoked on it. It can be determined by calling isMutable on the object.

toXMLString

public String toXMLString(boolean includeNSPrefix,
                          boolean declareNS)
                   throws XACMLException

Returns a String representation of this object

Specified by:

toXMLString in interface Subject

Parameters:

includeNSPrefix - Determines whether or not the namespace qualifier is prepended to the Element when converted

declareNS - Determines whether or not the namespace is declared within the Element.

Returns:

a string representation of this object

Throws:

XACMLException - if conversion fails for any reason

toXMLString

public String toXMLString()
                   throws XACMLException

Returns a string representation of this object

Specified by:

toXMLString in interface Subject

Returns:

a string representation of this object

Throws:

XACMLException - if conversion fails for any reason

makeImmutable

public void makeImmutable()

Makes the object immutable

Specified by:

makeImmutable in interface Subject

isMutable

public boolean isMutable()

Checks if the object is mutable

Specified by:

isMutable in interface Subject

Returns:

true if the object is mutable, false otherwise
