Method Details

checkAttributeSemantics

public void checkAttributeSemantics(PerunSessionImpl sess,
 User user,
 Facility facility,
 Attribute attribute)
                             throws WrongReferenceAttributeValueException,
WrongAttributeAssignmentException

Checks the new UID of the user at the specified facility. The new UID must not be lower than the min UID or greater than the max UID. Also no collision between existing user and the new user is allowed.

Specified by:

checkAttributeSemantics in interface UserFacilityAttributesModuleImplApi

Overrides:

checkAttributeSemantics in class UserFacilityAttributesModuleAbstract

Parameters:

sess - Perun session

user - User of the facility.

facility - Facility to be used by a user.

attribute - Attribute in relationship between facility and user.

Throws:

WrongReferenceAttributeValueException - if the attribute value has wrong/illegal semantics

WrongAttributeAssignmentException

fillAttribute

public Attribute fillAttribute(PerunSessionImpl sess,
 User user,
 Facility facility,
 AttributeDefinition attribute)
                        throws WrongAttributeAssignmentException

Fills the new UID for the user at the specified facility. First empty slot in range (minUID, maxUID) is returned.

Specified by:

fillAttribute in interface UserFacilityAttributesModuleImplApi

Overrides:

fillAttribute in class UserFacilityAttributesModuleAbstract

Parameters:

sess - Perun Session

user - User of the facility

facility - Facility to be used by user.

attribute - Attribute in relationship between facility and user to be filled in.

Returns:

Attribute which MAY be filled in

Throws:

WrongAttributeAssignmentException

getAttributeDefinition

public AttributeDefinition getAttributeDefinition()

Description copied from interface: AttributesModuleImplApi

Return attributes definition which is represented by the module

Specified by:

getAttributeDefinition in interface AttributesModuleImplApi

Overrides:

getAttributeDefinition in class AttributesModuleAbstract

Returns:

attribute definition

getAttributeValue

public Attribute getAttributeValue(PerunSessionImpl sess,
 User user,
 Facility facility,
 AttributeDefinition attributeDefinition)

Gets the value of the attribute f:uid-namespace and then finds the value of the attribute u:uid-namespace:[uid-namespace]

Specified by:

getAttributeValue in interface UserFacilityVirtualAttributesModuleImplApi

Overrides:

getAttributeValue in class UserFacilityVirtualAttributesModuleAbstract

Parameters:

sess - perun session

user - user which is needed for computing the value

facility - facility which is needed for computing the value

attributeDefinition - attribute to operate on

Returns:

getDependencies

public List<String> getDependencies()

Description copied from interface: AttributesModuleImplApi

Get list of attributes whose value are used in checking of validity of this attribute. In other words any change of these attributes' values can cause that value of this attribute is no longer valid.

An attribute should depend on all attributes which values are used in method "checkAttributeSemantics" defined in attribute module.

Specified by:

getDependencies in interface AttributesModuleImplApi

Overrides:

getDependencies in class AttributesModuleAbstract

Returns:

list of attributes this attribute depends on

See Also:

• AttributesManagerBl.checkAttributeDependencies(PerunSession, RichAttribute)

getStrongDependencies

public List<String> getStrongDependencies()

Description copied from interface: VirtualAttributesModuleImplApi

Get list of attributes which this attribute value is computed from. In other words attributes whose values change can also directly affect value of this attribute.

An attribute should strongly depend on all attributes which values are used in method "getAttributeValue" defined in attribute module for virtual attributes.

Specified by:

getStrongDependencies in interface VirtualAttributesModuleImplApi

Overrides:

getStrongDependencies in class UserFacilityVirtualAttributesModuleAbstract

Returns:

list of attributes this attribute strongly depends on

See Also:

• AttributesManagerBl.checkAttributeDependencies(PerunSession, RichAttribute)

setAttributeValue

public boolean setAttributeValue(PerunSessionImpl sess,
 User user,
 Facility facility,
 Attribute attribute)
                          throws WrongReferenceAttributeValueException

Description copied from interface: UserFacilityVirtualAttributesModuleImplApi

Method sets attributes' values which are dependent on this virtual attribute.

Specified by:

setAttributeValue in interface UserFacilityVirtualAttributesModuleImplApi

Overrides:

setAttributeValue in class UserFacilityVirtualAttributesModuleAbstract

user - user which is needed for computing the value

facility - facility which is needed for computing the value

attribute - attribute to operate on

Returns:

true if attribute was really changed

Throws:

WrongReferenceAttributeValueException
