Method Details

checkAttributeSemantics

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

Description copied from interface: ResourceAttributesModuleImplApi

Checks if value of this resource attribute has valid semantics.

Specified by:

checkAttributeSemantics in interface ResourceAttributesModuleImplApi

Overrides:

checkAttributeSemantics in class ResourceAttributesModuleAbstract

Parameters:

sess - perun session

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

attribute - attribute to check

Throws:

WrongAttributeAssignmentException

WrongReferenceAttributeValueException - if an referenced attribute against the parameter one is to be compared is not available

fillAttribute

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

Description copied from interface: ResourceAttributesModuleImplApi

This method tries to fill a value of the resource attribute. Value may be copied from some facility attribute.

Specified by:

fillAttribute in interface ResourceAttributesModuleImplApi

Overrides:

fillAttribute in class ResourceAttributesModuleAbstract

Parameters:

sess - perun session

resource - resource, attribute of which you want to fill

attributeDefinition - attribute to fill. If attributes already have set value, this value won't be overwriten. This means the attribute value must be empty otherwise this method won't fill it.

Returns:

attribute which MAY have filled value

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,
 Resource resource,
 AttributeDefinition attributeDefinition)

Description copied from interface: ResourceVirtualAttributesModuleImplApi

This method will return computed value.

Specified by:

getAttributeValue in interface ResourceVirtualAttributesModuleImplApi

Overrides:

getAttributeValue in class ResourceVirtualAttributesModuleAbstract

Parameters:

sess - PerunSession

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 ResourceVirtualAttributesModuleAbstract

Returns:

list of attributes this attribute strongly depends on

See Also:

• AttributesManagerBl.checkAttributeDependencies(PerunSession, RichAttribute)

removeAttributeValue

public boolean removeAttributeValue(PerunSessionImpl sess,
 Resource resource,
 AttributeDefinition attribute)
                             throws WrongAttributeValueException,
WrongReferenceAttributeValueException

Description copied from interface: ResourceVirtualAttributesModuleImplApi

Currently do nothing.

Specified by:

removeAttributeValue in interface ResourceVirtualAttributesModuleImplApi

Overrides:

removeAttributeValue in class ResourceVirtualAttributesModuleAbstract

Parameters:

sess - PerunSession

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

Throws:

WrongAttributeValueException

WrongReferenceAttributeValueException

setAttributeValue

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

Description copied from interface: ResourceVirtualAttributesModuleImplApi

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

Specified by:

setAttributeValue in interface ResourceVirtualAttributesModuleImplApi

Overrides:

setAttributeValue in class ResourceVirtualAttributesModuleAbstract

Parameters:

sess - PerunSession

resource - resource which is needed for computing the value

attribute - attribute to operate on

Returns:

true if attribute was really changed

Throws:

WrongReferenceAttributeValueException
