com.ibm.as400.access.IFSTextFileInputStream
public class IFSTextFileInputStream
Represents an integrated file system input stream for character data.
IFSTextFileInputStream objects are capable of generating file events
which call the following FileListener methods: fileClosed and fileOpened.
Note: This class is provided for situations where an InputStream is required. The preferred method of reading a text file is via IFSFileReader
.
The following example illustrates the use of IFSTextFileInputStream:
// Work with /File on the system eniac. AS400 as400 = new AS400("eniac"); IFSTextFileInputStream file = new IFSTextFileInputStream(as400, "/File");
// Read the first four characters of the file. String s = file.read(4); // Display the characters read. System.out.println(s); // Close the file. file.close();
