Method Details

getAttributeValue

public Attribute getAttributeValue(PerunSessionImpl perunSession,
 Facility facility,
 AttributeDefinition attribute)

Description copied from interface: FacilityVirtualAttributesModuleImplApi

This method will return computed value.

Specified by:

getAttributeValue in interface FacilityVirtualAttributesModuleImplApi

Parameters:

perunSession - perun session

facility - facility which is needed for computing the value

attribute - attribute to operate on

Returns:

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

Returns:

list of attributes this attribute strongly depends on

removeAttributeValue

public void removeAttributeValue(PerunSessionImpl perunSession,
 Facility facility,
 AttributeDefinition attribute)

Description copied from interface: FacilityVirtualAttributesModuleImplApi

Currently do nothing.

Specified by:

removeAttributeValue in interface FacilityVirtualAttributesModuleImplApi

Parameters:

perunSession -

facility - facility which is needed for computing the value

attribute - attribute to operate on

 AuditEvent message)
                                                    throws AttributeNotExistsException,
WrongAttributeAssignmentException

Description copied from interface: AttributesModuleImplApi

Gets message from auditer and resolves if it is needed to add another messages to DB about virtualAttribute changes.

Specified by:

resolveVirtualAttributeValueChange in interface AttributesModuleImplApi

Overrides:

resolveVirtualAttributeValueChange in class AttributesModuleAbstract

Parameters:

perunSession -

message -

Returns:

list of additional messages for auditer to log it

Throws:

AttributeNotExistsException

setAttributeValue

public boolean setAttributeValue(PerunSessionImpl perunSession,
 Facility facility,
 Attribute attribute)
                          throws WrongReferenceAttributeValueException

Description copied from interface: FacilityVirtualAttributesModuleImplApi

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

Specified by:

setAttributeValue in interface FacilityVirtualAttributesModuleImplApi

Parameters:

perunSession -

facility - facility which is needed for computing the value

attribute - attribute to operate on

Returns:
