Client item (IDL code)
Create a Client in the following ways:
• On an Internal Component Diagram: on the diagram's tab, click the 
Client button, and then click within the Component or Component Part on which you want to create the Client.
Client button, and then click within the Component or Component Part on which you want to create the Client.• Right-click the Component, Connector or Port Type that is to own the Client, and select > > .
When you create a Client, you must create or select a type (Interface) for that Client.
The isMultiple property specifies whether the client represents a uses declaration or a uses multiple declaration. By default, the isMultiple property of a Client is set to FALSE. To set isMultiple to TRUE: right-click the Client, and select > . From the dialog, select TRUE, and then click OK.
The Asynchronous property specifies whether the client is asynchronous. By default, the Asynchronous property of a Client is set to FALSE. To set Asynchronous to TRUE: right-click the Client, point to Set, and then click Asynchronous. From the dialog, select TREU, and then click OK.
To change the type of a Client: right-click the Client, point to Set, and then click Type. From the dialog select the Interface you want to use as a type. To make the name of the Client match the new type: right-click the Client, and then click Synchronize IDL Element Names.
By default, the name of the Client is set to that of the Interface it uses as a type. If the name of a Client or Interface is changed and you want to change the name of the Client to match the name of the Interface it uses as a type: right-click the Client, and then click Synchronize IDL Element Names. Note that the name of the Client is also set to the name of the Interface it uses as a type when the Synchronize IDL Element Names command is used from the following items: the Interface that is used as type, the Component that owns the Client, and the scoping Package of the Client or Interface.
For information about connecting a Client to other items on an Internal Component Diagram, see Rules for connecting items on an internal component diagram.
When shown on an Internal Component Diagram, a Client's notation is as follows:
Note that on an Internal Component Diagram, a Client's view options are set through the Port entry.
A Client is based on a UML Attribute or Role.
The following sections provide information about how a Client is used in the model.
Owned By
Note that when you create a Client on a Component Part, the Client is created as a child of the Component Part's type, that is, a Component.
Owns
Connection (UML Association) - the Connection is owned jointly by the two items it links. See Rules for connecting items on an internal component diagram.Shown on these diagrams

• Asynchronous - specifies that the Client is asynchronous.
• isMultiple - specifies that the Client uses a multiple declaration.
