Models toString() Implementation

[ppyordanov]

Models currently have stubs for toString(), but the method has not been implemented. It will be used for model manipulation feedback in the console during runtime by using a console logger.

At the moment logging is served by _SLF4J_, a Java logging facade: http://www.slf4j.org/ .

toString() methods have been implemented for all of the model classes in use (DataReading, Route, Device) using a StringBulder to improve execution speed. It displays object class as well as all of the attribute values for convenient referencing. The method is extensively used on the server for process logging and paired with SLF4J has been significantly helpful for identifying bugs and code sections that need refactoring:

Below is the skeleton function structure (following the facade pattern):

    @Override
    public String toString() {

        StringBuilder string = new StringBuilder();
        String newLine = System.getProperty("line.separator");

        string.append(this.getClass().getName() + " Object {" + newLine);
        string.append("id: " + id + newLine);
        //model attributes
        ..

        return string.toString();

    }
