Module dmntk_model::model
source · Expand description
Model for Decision Requirements Graph (DRG) depicted in one or more Decision Requirements Diagrams (DRD).
Structs
- tdb
- The class AuthorityRequirement is used to model an authority requirement, as represented by an arrow drawn with a dashed line and a filled circular head in a DRD
- A business knowledge model has an abstract part, representing reusable, invocable decision logic, and a concrete part, which mandates that the decision logic must be a single FEEL boxed function definition.
- A Context is composed of any number of model context entries, which are instances of ContextEntry.
- The class ContextEntry is used to model
FEELcontext entries when a context is modeled as a Context element. - Defines bounds.
- Defines RGB color.
- Defines dimensions.
- Defines point.
- The DecisionService class is used to define named decision services against the decision model contained in an instance of Definitions.
- Decision table.
- Definitions element is the outermost containing object for all elements of a DMN decision model. It defines the scope of visibility and the namespace for all contained elements.
- Struct defines line inside DecisionService.
- DmnDiagram is the container of DmnDiagramElement (DmnShape (s) and DmnEdge (s)). DmnDiagram cannot include other DmnDiagrams.
- Struct represents the depiction of some textual information about a DMN element.
- DmnShape represents a Decision, a BusinessKnowledgeModel, an InputData element, a KnowledgeSource, a DecisionService or a TextAnnotation that is depicted on the diagram.
- DmnStyle is used to keep some non-normative visual attributes such as color and font.
- Element represents an element from another metamodel.
- The ExtensionAttribute element contains an Element or a reference to an Element from another metamodel. An ExtensionAttribute also has a name to define the role or purpose of the associated element.
- The ExtensionElements element is a container to aggregate elements from other metamodels inside any DmnElement.
- FunctionItem defines the signature of a function: the parameters and the output type of the function.
- FunctionItem defines the signature of a function: the parameters and the output type of the function.
Importclass is used when referencing external elements, either DMN DRGElement or ItemDefinition instances contained in other Definitions elements, or non-DMN elements, such as an XML Schema or a PMML file.- The class InformationRequirement is used to model an information requirement, as represented by a plain arrow in a DRD.
- InputData is used to model the inputs of a decision whose values are defined outside of the decision model.
- Invocation is a mechanism that permits the evaluation of one value expression – the invoked expression – inside another value expression – the invoking expression – by binding locally the input variables of the invoked expression to values inside the invoking expression.
- ItemDefinition is used to model the inputs of a decision, whose values are defined outside of the decision model.
- The class KnowledgeRequirement is used to model a knowledge requirement, as represented by a dashed arrow in a DRD.
- The class KnowledgeSource is used to model authoritative knowledge sources in a decision model. In a DRD, an instance of KnowledgeSource is represented by a
knowledge sourcediagram element. - A List is simply a list of elements, which are instances of Expressions.
- LiteralExpression is used to model a value expression whose value is specified by text in some specified expression language.
- tdb
- UnaryTests is used to model a boolean test, where the argument to be tested is implicit or denoted with a ?. Test is specified by text in some specified expression language.
Enums
- Aggregator function for
COLLECThit policy. - Enumeration of concrete instances of BusinessContextElement.
- Defines the king of element alignment.
- Defines known colors.
- Orientation of the decision table.
- Defines possible elements of DmnDiagramElement.
- In DMN™ model DrgElement is the abstract superclass for all DMN™ elements that are contained within Definitions and that have a graphical representation in a DRD. This enumeration specifies the list of DRGElements contained in Definitions.
- Enumeration of concrete instances of abstract Expression, which are:
- Defines the type of the FunctionDefinition. The default value is
FEEL. Supported values also includeJavaandPMML. - Hit policy.
- Instances of
Invocableinterface. - Item definition types.
Constants
Traits
- The abstract class BusinessContextElement, and its concrete specializations PerformanceIndicator and OrganizationUnit are placeholders, anticipating a definition to be adopted from other OMG meta-models, such as OMG OSM when it is further developed.
- DmnElement is the abstract superclass for the Decision Model elements. It provides the optional attributes
id,descriptionandlabel, which other elements will inherit. - Expression is an abstract class that describes the logic by which a modeled decision shall be made, or pieces of that logic.
- FeelTypedElement adds the
FEELtype attributes to element. Invocableis used to model the inputs of a decision whose values are defined outside of the decision model.- RequiredTypeRef adds the required type reference to element.
- RequiredVariable adds the required reference to InformationItem.
