Field Detail

identifier

private Identifier identifier

Identifier of this element.

target

private RBACTarget target

Target of this element.

Constructor Detail

RBACPolicyElement

protected RBACPolicyElement()

RBACPolicyElement

public RBACPolicyElement(URI id)
                  throws ParsingException

Create an RBACPolicyElement.

Parameters:

id - Identifier of this element (domain:assignment:label).

Throws:

ParsingException - Indicates a malformed identifier representation.

RBACPolicyElement

public RBACPolicyElement(Identifier id)

Create an RBACPolicyElement.

Parameters:

id - Identifier of this element (domain:assignment:label).

RBACPolicyElement

public RBACPolicyElement(PolicyTreeElement element)
                  throws ParsingException

Create an RBACPolicyElement from its PolicyTreeElement representation.

Parameters:

element - The element's PolicyTreeElement representation.

Throws:

ParsingException

Method Detail

parse

public abstract void parse(PolicyTreeElement element)
                    throws ParsingException

Throws:

ParsingException

parse

public void parse(Target target)
           throws ParsingException

Allows subclass specific parsing of the policy element's Targetto an RBACTarget. For that, it must be overwritten by subclasses. The default implementation simply parses the target using the RBACTarget.parse(Target) method. if the target is not null.

Parameters:

target - The target to parse.

Throws:

ParsingException - Signals errors during the parsing process.

toPolicyTreeElement

public abstract PolicyTreeElement toPolicyTreeElement()

Returns the PolicyTreeElement representation of this policy element. Should be one of

Rule

,

Policy

or

PolicySet

Returns:

The policy element's PolicyTreeElement representation.

add

public abstract boolean add(RBACPolicyElement element)

Adds another policy element to this element. Shall permit to update/add elements to the target.

Parameters:

element - The element to add.

Returns:

true if the element has been added succesfully, false otherwise.

remove

public abstract boolean remove(RBACPolicyElement element)

Removes another policy element from this element. Shall permit to update/remove elements from the target.

Parameters:

element - The element to remove.

Returns:

true if the element has been added succesfully, false otherwise.

setIdentifier

public void setIdentifier(URI id)
                   throws ParsingException

Sets the identifier of this element.

Parameters:

id - The element's identifier.

Throws:

ParsingException - Indicates a malformed identifier representation.

setIdentifier

public void setIdentifier(Identifier id)

Sets the identifier of this element.

Parameters:

id - The element's identifier.

getIdentifier

public Identifier getIdentifier()

Gets the identifier of this element.

Returns:

The element's identifier.

getTarget

public RBACTarget getTarget()

Gets the target of this element.

Returns:

Returns the target.

setTarget

public void setTarget(RBACTarget target)

Sets target of this element.

Parameters:

target - The target to set.

hashCode

public int hashCode()

The hash code corresponds to the hash code of the assigment's identifier.

See Also:

Object.hashCode()

equals

public boolean equals(Object obj)

Compares the specified object with this assignment. Returns true if the specified object is also a RBACTarget, both identifiers and both targets are equal.

Parameters:

obj - Object to be compared for equality with this element.

Returns:

true if the specified Object is equal to this element.

toString

public String toString()
