Method Details

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:

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

removeAttributeValue

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

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

setAttributeValue

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

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
