Provides methods for setting dependencies in the context of a constraint and its data model.

Dependencies and validation

This context provides methods for declaring a constraint's dependencies. Constraint dependencies are used to minimize the number of calls to these constraints during the validation process. For instance, in the context of programmatic constraints, calls to the method Constraint.checkOccurrence(Object, ValueContextForValidation) will be minimized if dependencies are defined. Three modes are available:

1. Local dependency: In this mode, the validation result of the current constraint depends only on the local value of the underlying node. Besides modification of this local value, the validation result will not be affected by any external events. This mode is enabled by calling the method ConstraintContext.setDependencyToLocalNode().
2. Explicit dependencies: In this mode, the validation result of the current constraint depends only on updates of the source nodes that have been specified explicitly. Besides such updates and modification of the local value, the validation result will not be affected by any external events. One or more explicit dependencies can be specified using methods:
   • addDependencyToModify(Path).
   • addDependencyToModify(SchemaNode).
   • addDependencyToInsertAndDelete(Path).
   • addDependencyToInsertAndDelete(SchemaNode).
   • addDependencyToInsertDeleteAndModify(Path).
   • addDependencyToInsertDeleteAndModify(SchemaNode).
   • addDependencyToInsertAndDeleteInOtherInstance(Path, AdaptationReference).
   • addDependencyToInsertAndDeleteInOtherInstance(Path, AdaptationReference, HomeKey).
   • addDependencyToInsertDeleteAndModifyInOtherInstance(Path, AdaptationReference).
   • addDependencyToInsertDeleteAndModifyInOtherInstance(Path, AdaptationReference, HomeKey).
   • addDependencyToInsertDeleteAndModifyInOtherInstance(SchemaNode, AdaptationReference).
   • addDependencyToInsertDeleteAndModifyInOtherInstance(SchemaNode, AdaptationReference, HomeKey).
3. Unknown dependencies (default): In this mode, the validation result of the current constraint depends on unknown sources or events (for example, data stored in an external system). This is the default mode, enabled if neither of the above methods has been called or if the element containing this constraint is computed by a value function or is an inherited field (defines the property osd:inheritance).

Attention:

• Dependencies on computed values and inherited fields (define the property osd:inheritance) are not allowed. Constraints applied on elements defining a value function will be automatically set to Unknown dependencies mode. Consequently, if a constraint attempts to specify an explicit dependency, an IllegalArgumentException will be thrown.
• If local or explicit dependencies are specified, they must be in complete accordance with the constraint's actual implementation. More precisely, if a dependency is missing, the validation result could be inaccurate.
• It is not mandatory to specify dependencies. The specification of local or explicit dependencies is useful when large volumes of data must be validated and/or the validation algorithm is particularly expensive. In other cases, the default unknown dependencies mode is sufficient.
• In EBX® user interface mode, the current constraint is always checked when user input is submitted.

Method Details

addDependencyToModify

void addDependencyToModify(SchemaNode aLocalSource)

Specifies that the validation result of the current constraint depends on the value of the specified source node in the same record.

In the scope of incremental validation, this implies that any modification to the source node's value will trigger a revalidation of this constraint within the context of the altered record.

In the context of a constraint on a table, this method can be used to add a modification dependency to a dataset node.

Attention:

• A call to this method implies that all dependencies are explicitly declared (explicit dependencies mode). For more information, see Dependencies and validation above.
• If the source or current node are computed by a computed value in unknown dependencies mode mode or are an inherited field (defines the property osd:inheritance), then this constraint will be considered to be in unknown dependencies mode.

Throws:

IllegalStateException - if a local dependency has been set to this constraint.

IllegalStateException - if this constraint is set to Unknown dependencies mode.

IllegalArgumentException - if the specified source node does not have a local value; that is:

• it is not a terminal node or under a terminal node.
• it is a table node.
• it is a table record node not in the same table as the current node (if this node is also in a table record).
