Parameters of Action "read"
Defining a "read" Action
To read a file with the file system adapter, you need to define a read action on an action having the stereotype <<FileSystemAdapter>>. You can do this manually or with the help of the xUML Action Wizard (see context menu of the action node).
Figure: Reading a File
The file content is of base type Blob and can be stored either in an output object buffer, as in the above diagram, or in an output pin; in both cases the output must be named data.
The path and file name of the file you want to access are defined in the component diagram.
| The link from the activity diagram to the physical information is established by an alias (in the present example: FileAlias). See File System Components for more information on file system aliases. For information on how to access a file or directory dynamically refer to Dynamic File Access. |
Properties of the File System Adapter Action
