Method Details

checkAttributeSemantics

public void checkAttributeSemantics(PerunSessionImpl sess,
 Group group,
 Resource resource,
 Attribute attribute)
                             throws WrongAttributeAssignmentException,
WrongReferenceAttributeValueException

Description copied from interface: GroupResourceAttributesModuleImplApi

Checks if value of this group-resource attribute has valid semantics.

Specified by:

checkAttributeSemantics in interface GroupResourceAttributesModuleImplApi

Overrides:

checkAttributeSemantics in class GroupResourceAttributesModuleAbstract

Parameters:

sess - perun session

group - group

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

attribute - attribute to check

Throws:

WrongAttributeAssignmentException

WrongReferenceAttributeValueException

fillAttribute

public Attribute fillAttribute(PerunSessionImpl sess,
 Group group,
 Resource resource,
 AttributeDefinition attributeDefinition)
                        throws WrongAttributeAssignmentException

Description copied from interface: GroupResourceAttributesModuleImplApi

This method MAY fill an attribute at the specified resource.

Specified by:

fillAttribute in interface GroupResourceAttributesModuleImplApi

Overrides:

fillAttribute in class GroupResourceAttributesModuleAbstract

Parameters:

sess - perun session

group - group

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

attributeDefinition - attribute to fill in

Returns:

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,
 Group group,
 Resource resource,
 AttributeDefinition attributeDefinition)

Description copied from interface: GroupResourceVirtualAttributesModuleImplApi

This method will return computed value.

Specified by:

getAttributeValue in interface GroupResourceVirtualAttributesModuleImplApi

Overrides:

getAttributeValue in class GroupResourceVirtualAttributesModuleAbstract

Parameters:

sess - perun session

group - group which is needed for computing the value

resource - resource 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 GroupResourceVirtualAttributesModuleAbstract

Returns:

list of attributes this attribute strongly depends on

See Also:

• AttributesManagerBl.checkAttributeDependencies(PerunSession, RichAttribute)

removeAttributeValue

public boolean removeAttributeValue(PerunSessionImpl sess,
 Group group,
 Resource resource,
 AttributeDefinition attribute)

Description copied from interface: GroupResourceVirtualAttributesModuleImplApi

Currently do nothing.

Specified by:

removeAttributeValue in interface GroupResourceVirtualAttributesModuleImplApi

Overrides:

removeAttributeValue in class GroupResourceVirtualAttributesModuleAbstract

group - group which is needed for computing the value

resource - resource which is needed for computing the value

attribute - attribute to operate on

Returns:

true if attribute was changed (deleted) or false if attribute was not present in a first place

setAttributeValue

public boolean setAttributeValue(PerunSessionImpl sess,
 Group group,
 Resource resource,
 Attribute attribute)
                          throws WrongReferenceAttributeValueException

Description copied from interface: GroupResourceVirtualAttributesModuleImplApi

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

Specified by:

setAttributeValue in interface GroupResourceVirtualAttributesModuleImplApi

Overrides:

setAttributeValue in class GroupResourceVirtualAttributesModuleAbstract

group - group which is needed for computing the value

resource - resource which is needed for computing the value

attribute - attribute to operate on

Returns:

true if attribute was really changed

Throws:

WrongReferenceAttributeValueException
