Objects

Objects are created in Enterprise Architect by generating text in the following form:

objectType

{

 objectProperties

}

where:

objectType is one of the following object types:

• Action
• ActionPin
• Activity
• ActivityParameter
• ActivityPartition
• ActivityRegion
• Actor
• Association
• Change
• Class
• Collaboration
• CollaborationOccurrence
• Component
• DeploymentSpecification
• DiagramFrame
• Decision
• EntryPoint
• Event
• ExceptionHandler
• ExecutionEnvironment
• ExitPoint
• ExpansionNode
• ExpansionRegion
• ExposedInterface
• GUIElement
• InteractionFragment
• InteractionOccurrence
• InteractionState
• Interface
• InterruptibleActivityRegion
• Issue
• Iteration
• Object
• ObjectNode
• MessageEndpoint
• Node
• Package
• Parameter
• Part
• Port
• ProvidedInterface
• RequiredInterface
• Requirement
• Sequence
• State
• StateMachine
• StateNode
• Synchronization
• Table
• TimeLine
• Trigger
• UMLDiagram
• UseCase.

objectProperties is zero, or one or more of the following properties:

• Abstract
• Alias
• Arguments
• Author
• Cardinality
• Classifier
• Complexity
• Concurrency
• Filename
• Header
• Import
• IsActive
• IsLeaf
• IsRoot
• IsSpecification
• Keyword
• Language
• Multiplicity
• Name
• Notes
• Persistence
• Phase
• Scope
• Status
• Stereotype
• Version
• Visibility.

and zero, or one or more of the following elements:

• Attribute
• Classifier
• Parameter
• Operation
• Parent
• Tag
• XRef
• Any object.

Classes

A simple Class can be created as follows:

Class

{

       name = "Example"

}

It is then easy to add to this. The following example sets the language to C++, and adds a Tagged Value and an attribute:

Class

{

       name = "Example"

       language = "C++"

       Tag

       {

               name = "defaultCollectionClass"

               value = "List"

       }

       Attribute

       {

               name = "count"

               type = "int"

       }

}

Attributes

Attributes are created with the same structure as objects, and include the following properties:

• Alias
• Classifier
• Collection
• Container
• Containment
• Constant
• Default
• Derived
• LowerBound
• Name
• Notes
• Ordered
• Scope
• Static
• Stereotype
• Type
• UpperBound
• Volatile.

and the following elements:

• Classifier
• Tag
• XRef.

Operations

Operations are created with the same structure as objects, and include the following properties:

• Abstract
• Alias
• Behavior
• Classifier
• Code
• Constant
• IsQuery
• Name
• Notes
• Pure
• ReturnArray
• Scope
• Static
• Stereotype
• Type.

and the following elements:

• Classifier
• Parameter
• Tag
• XRef.

Parameters

Parameters are created with the same structure as objects, and include the tag element and the following properties:

• Classifier
• Default
• Fixed
• Name
• Notes
• Kind
• Stereotype.

Packages

Packages differ from other objects in the following ways:

• A reduced set of properties of alias, author, name, namespaceRoot, notes, scope, stereotype and version
• The extra property namespaceRoot
• Must have a name specified
• Name can be a qualified name; when a qualified name is specified the properties given are applied only to the final package
• Can contain other packages
• Can't contain attributes and operations.

Tables

Tables are a special sort of object, with the following differences from other object types:

• Can include columns and primary keys
• Can't include attributes.

Columns

Columns are similar to attributes, but have an autonumber element containing Startnum and increment, and the following added properties:

• Length
• NotNull
• Precision
• PrimaryKey
• Scale
• Unique.
