Creating a user routine

Procedure

  1. In the Repository tree view, expand Code to display the Routines folder.
  2. Right-click Routines and select Create routine.
  3. The New routine dialog box opens. Enter its name, in this example MyRoutineDemo, a purpose and a description.
  4. Click Finish to close the dialog box.
    Information noteNote: The newly created routine appears in the Repository tree view, directly below the Routines node.

    The routine editor opens to reveal a model routine which contains a simple example, by default, comprising descriptive text in blue, followed by the corresponding code.

  5. Replace the model with the following code and press Ctrl+S to save the routine.

    It has a ByteArrayFromFile function, that requires a file path as input parameter and is used to read a file and convert it to a byte array.

    package routines;public class MyRoutineDemo {
public static byte[] ByteArrayFromFile(String filepath) {
try{ 
java.io.File file=new java.io.File(filepath);
java.io.FileInputStream fis = new java.io.FileInputStream(file);
int fileLength = (int) file.length();
byte[] incoming_file_data = new byte[fileLength]; // allocate byte array of right size
fis.read(incoming_file_data, 0, fileLength ); // read into byte array
fis.close();
return incoming_file_data;
}catch(Exception err){
err.printStackTrace();return null;
}
}
}
