Defining a "readLine" Action
To read a file line by line with the file system adapter, you need to define a readLine action on an action having the stereotype <<FileSystemAdapter>>. You can do this manually (refer to Figure: The Specification Dialog of the File System Adapter) or with the help of the E2E Action Wizard (see context menu of the action node).
Figure: Reading a File Line by Line
Image Modified
The file content line is of the base type String and is stored in an output object named line. If line is not given back by the file system adapter (line=NULL), the end of file has been reached.
The path and file name of the file you want to access are defined in the component diagram.
