Method Details

checkAttributeSemantics

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

Description copied from interface: FacilityAttributesModuleImplApi

Checks if value of this facility attribute has valid semantics.

Specified by:

checkAttributeSemantics in interface FacilityAttributesModuleImplApi

Overrides:

checkAttributeSemantics in class FacilityAttributesModuleAbstract

Parameters:

sess - perun session

facility - facility for which you want to check validity of attribute

attribute - attribute to check

Throws:

WrongReferenceAttributeValueException - if the attribute value has wrong/illegal semantics

WrongAttributeAssignmentException

fillAttribute

public Attribute fillAttribute(PerunSessionImpl sess,
 Facility facility,
 AttributeDefinition attributeDefinition)

Description copied from interface: FacilityAttributesModuleImplApi

This method MAY fill an attribute at the specified resource.

Specified by:

fillAttribute in interface FacilityAttributesModuleImplApi

Overrides:

fillAttribute in class FacilityAttributesModuleAbstract

Parameters:

sess - perun session

facility - facility for which you want to check validity of attribute

attributeDefinition - attribute to fill in

Returns:

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,
 Facility facility,
 AttributeDefinition attributeDefinition)

Description copied from interface: FacilityVirtualAttributesModuleImplApi

This method will return computed value.

Specified by:

getAttributeValue in interface FacilityVirtualAttributesModuleImplApi

Overrides:

getAttributeValue in class FacilityVirtualAttributesModuleAbstract

Parameters:

sess - perun session

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 FacilityVirtualAttributesModuleAbstract

Returns:

list of attributes this attribute strongly depends on

See Also:

• AttributesManagerBl.checkAttributeDependencies(PerunSession, RichAttribute)

removeAttributeValue

public void removeAttributeValue(PerunSessionImpl sess,
 Facility facility,
 AttributeDefinition attributeDefinition)

Description copied from interface: FacilityVirtualAttributesModuleImplApi

Currently do nothing.

Specified by:

removeAttributeValue in interface FacilityVirtualAttributesModuleImplApi

Overrides:

removeAttributeValue in class FacilityVirtualAttributesModuleAbstract

Parameters:

sess -

facility - facility which is needed for computing the value

attributeDefinition - attribute to operate on

setAttributeValue

public boolean setAttributeValue(PerunSessionImpl sess,
 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

Overrides:

setAttributeValue in class FacilityVirtualAttributesModuleAbstract

Parameters:

sess -

facility - facility which is needed for computing the value

attribute - attribute to operate on

Returns:

true if attribute was really changed

Throws:

WrongReferenceAttributeValueException
