Method Detail

load

public void load(java.lang.String fileName)
          throws java.io.IOException

Loads given file. It works exactly as Properties.load with a file input stream to the given file, except that the file is parsed the following way allowing to compress some property names using { and }. When a bracket is present, it must be the only non-space element of a line. The last property defined before the opening bracket define the prefix that is added to all the properties defined included between brackets. In other words, a construct like this:

  control.degree GraphObserver 
  {
    protocol newscast
    undir
  }
  

is equivalent to the definition of these three properties:

  control.degree GraphObserver 
  control.degree.protocol newscast
  control.degree.undir
  

Nested brackets are possible. The rule of the last property before the opening bracket applies also to the inside brackets, with the prefix being the complete property definition (so, including the prefix observed before). Example:

        control.1 DynamicNetwork
        {
          add CRASH
          substitute
          init.0 WireKOut 
          {
            degree DEGREE
            protocol 0
          }
        }
  

defines the following properties:

        control.1 DynamicNetwork
        control.1.add CRASH
        control.1.substitute
        control.1.init.0 WireKOut 
        control.1.init.0.degree DEGREE
        control.1.init.0.protocol 0
  

Know limitations: The parsing mechanism is very simple; no complex error messages are provided. In case of missing closing brackets, the method will stop reporting the number of missing brackets. Additional closing brackets (i.e., missing opening brackets) produce an error messages reporting the line where the closing bracket is present. Misplaced brackets (included in lines that contains other characters) are ignored, thus may indirectly produce the previous error messages.
