Parameter extends GeneratedElement, NamedElement

Examples

• ImplicitParameterValues.iaml (source)
  • A Label or InputTextField can be used as a ParameterEdgesSource;the value provided is loaded at runtime from the fieldValueof the VisibleThing. [ImplicitParameterValues]
• NavigateWithParameter.iaml (source)
  • A Parameter can connect to a ECARule in order toprovide named QueryParameters to the destination Frame. [NavigateWithParameter]

Implementation Notes

• If a DomainIterator is using a query with more than one parameter,and the Parameters are not named, the name of thedata source will be used to match up a query. [DomainInheritance]
• Any incoming named Parameters to a ECARule will bepassed along as named GET parameters to the destination Frame through QueryParameters. [NavigateWithParameter]
• If a Changeable is used as the source of a Parameter, the fieldValue of the Changeable is used as the value. [Parameters]
• Any incoming named Parameters to a ECARule to a Frame will be passed along as named GET parameters to the destination. [OperationCall]

Inference Rules

• An AccessControlHandler protecting a Session with a defined Role-based access requirement will provide the default Role as a Parameter to the created LoginHandler. [users]
• The DomainIterator representing the current instance of an AccessControlHandler check, protecting a Frame within a Session, will be provided as a Parameter to the generated LoginHandler. [users]

• The navigation rule from the link Button generated for a DetailWire, as contained by an IteratorList, will be supplied the current value within the source DomainInstance, representing the primaryKey of the source DomainType. [detail-wires]
• The navigation rule from the link Button generated for a DetailWire, not contained by an IteratorList, will be supplied the current value within the source DomainInstance, representing the primaryKey of the source DomainType. [detail-wires]
• When a DetailWire is connected from a Frame that contains a DomainIterator to a target Frame, a new selected DomainIterator will be used to select content based on primary key. [detail-wires]
• The 'target' Value defined in a 'last' Button defined for navigating a DomainIterator, as defined by a SetWire, will be used as a Parameter for executing the jump Operation on that iterator. [paginate]
• The current results count of the DomainIterator will be used as a Parameter to update the 'results' Label defined for navigating a DomainIterator with a SetWire when the containing InputForm is accessed. [paginate]
• The current results count of the DomainIterator will be used as a Parameter to update the 'results' Label defined for navigating a DomainIterator with a SetWire when the iterator changes. [paginate]
• A SyncWire connecting two elements with a Function 'can sync?' will only permit synchronisation if the value can be cast successfully. [casting]
• A login Frame for a LoginHandler of type DOMAIN_OBJECT will contain an InputTextField for every DomainAttribute defined as a Parameter to that LoginHandler. [login-handler]
• A login Frame for a LoginHandler of type USER will contain an InputTextField for every non- primary key DomainAttribute within the Role defined as a Parameter to that LoginHandler. [login-handler]
• A Frame contained by a Session protected by a LoginHandler of type SECRET_KEY will navigate to the login Frame if the 'check key' Operation fails. [login-handler]
• A Frame contained by a Session protected by a LoginHandler of type SECRET_KEY will provide the stored key as a Parameter to the executed 'check key' Operation. [login-handler]
• Each Value 'current XXX' set by a a LoginHandler of type DOMAIN_OBJECT will be provided as a Parameter to the handler. [login-handler]
• Every InputTextField defined in the login form for the login Frame for a LoginHandler of type DOMAIN_OBJECT will be provided as a named Parameter to the 'do login' Operation of the handler. [login-handler]
• Every InputTextField defined in the login form for the login Frame for a LoginHandler of type USER will be provided as a named Parameter to the 'do login' Operation of the handler. [login-handler]
• When a Changeable element is connected to an CanBeSynced element by a SetWire, the value of the source element will be provided as a Parameter to the updating ECARule. [set-wires]
• When a CanBeSynced element is connected to an CanBeSynced element by a SetWire, the value of the source element will be provided as a Parameter to the updating ECARule. [set-wires]
• When a Changeable element is connected to a Value by a SetWire, the value of the source element will be provided as a Parameter to the updating ECARule. [set-wires]
• All Parameters for each conditions against a SetWire will be copied to each SimpleCondition subsequently created for ECARules connected to the onAccess Events. [conditions]
• All Parameters for each conditions against a SetWire will be copied to each SimpleCondition subsequently created for ECARules connected to the onChange Events. [conditions]
• When an InputTextField is connected to a CanBeSynced element by an instant SetWire, the value of the source element will be provided as a Parameter to the updating ECARule. [set-wires]
• When a CanBeSynced element is connected to an Accessible element by a SetWire, the fieldValue of the source element will be used as a Parameter to initialise the target through the 'init' Operation. [set-wires]
• Every 'init' Operation executed when a Session is initialised due to a SetWire between a Frame within that session, to another element outside of that session, will be provided the fieldValue of the source element as a Parameter. [set-wires]
• Every 'init' Operation executed when a Session is initialised due to a SetWire between a VisibleThing within that session, to another element outside of that session, will be provided the fieldValue of the source element as a Parameter. [set-wires]
• When a CanBeSynced element is connected to an CanBeSynced element by a SyncWire, the value of the source element will be provided as a Parameter to the updating ECARule. [sync-wires]
• All Parameters for each conditions against a SyncWire will be copied to each ECARule subsequently created as connected to the onAccess Events. [conditions]
• All Parameters for each conditions against a SyncWire will be copied to each ECARule subsequently created as connected to the onChange Events. [conditions]
• When an InputTextField is connected to a CanBeSynced element by an instant SyncWire, the value of the source element will be provided as a Parameter to the updating ECARule. [sync-wires]
• For elements connected by a SyncWire, the 'onAccess' Event executing the 'init' Operation will only execute if the source fieldValue can be cast successfully. [casting]

Attributes

Inherited Attributes

• generatedRule : EString (optional)
  To assist in debugging, this attribute may be populated with the name of the model completion rule that created this element. More extensive traceability support may be provided in the future.
• id : EString (optional)
  A unique identifier for this model element. Should be globally unique.
• isGenerated : EBoolean (optional)
  Set to true if the current element has been generated.
• name : EString (optional)
  A non-unique string that names a given object.

References

• parameterTerm : [1] ParameterEdgeDestination [opposite: inParameterEdges]
  The target of the Parameter.
• parameterValue : [1] ParameterEdgesSource [opposite: outParameterEdges]
  The source value of the Parameter.

Inherited References

• generatedBy : [0...*] GeneratesElements [opposite: generatedElements]
  A list of elements that generated this element; conversely, overriding the source will prevent this element from being created.
