Method Details

getAttributeValue

public Attribute getAttributeValue(PerunSessionImpl perunSession,
 UserExtSource ues,
 AttributeDefinition attribute)

Description copied from interface: UserExtSourceVirtualAttributesModuleImplApi

This method will return computed value.

Specified by:

getAttributeValue in interface UserExtSourceVirtualAttributesModuleImplApi

Parameters:

perunSession - PerunSession

ues - UserExternalSource

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 boolean removeAttributeValue(PerunSessionImpl perunSession,
 UserExtSource ues,
 AttributeDefinition attribute)

Description copied from interface: UserExtSourceVirtualAttributesModuleImplApi

Currently do nothing.

Specified by:

removeAttributeValue in interface UserExtSourceVirtualAttributesModuleImplApi

Parameters:

perunSession - PerunSession

ues - UserExternalSource

attribute - attribute to operate on

Returns:

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

resolveVirtualAttributeValueChange

public List<AuditEvent> resolveVirtualAttributeValueChange(PerunSessionImpl perunSession,
 AuditEvent message)

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

setAttributeValue

public boolean setAttributeValue(PerunSessionImpl perunSession,
 UserExtSource ues,
 Attribute attribute)

Description copied from interface: UserExtSourceVirtualAttributesModuleImplApi

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

Specified by:

setAttributeValue in interface UserExtSourceVirtualAttributesModuleImplApi

Parameters:

perunSession - PerunSession

ues - UserExternalSource

attribute - attribute to operate on

Returns:

true if attribute was really changed
