Re: [Cilib-users] CIlib 0.6.12 Release

[Gary P. <gpa...@gm...>]

Hi,

I'm glad you're finding your feet :)

As for the xsd:

W3C defines that an XSD dictates:
    * defines elements that can appear in a document
    * defines attributes that can appear in a document
    * defines which elements are child elements
    * defines the order of child elements
    * defines the number of child elements
    * defines whether an element is empty or can include text
    * defines data types for elements and attributes
    * defines default and fixed values for elements and attributes

With that in mind, CIlib has been designed as a library of algorithms,
with each algorithm (including it's component parts) implemented as
JavaBeans.

This implies that for each member in each class, there should be an
associated getter / setter method if that property is to be exposed.

The XML files of CIlib use "the code itself" as the XML specifications.
This means that a predefined XSD is simply *not* possible.

Let me demonstrate, in the following XML snippet:

<algorithm class="pso.PSO" >
  <topology class="entity.topologies.LBestTopology">
    <neighbourhoodSize
class="controlparameters.ConstantControlParameter" parameter="3" />
  </topology>
</algorithm>


Dictates that the current algorithm will be an instance of the
net.sourceforge.cilib.pso.PSO class (note that the net.sourceforge.cilib
is automatically prepended to make your life a little simpler). This
class in turn has a property on it called "topology" which we want to be
an LBestTopology. The LBestTopology in turn has a property on it called
'neighbourhoodSize' which we set to a value of 3.

The above XML can also be written as:


<algorithm class="pso.PSO" >
  <topology class="entity.topologies.LBestTopology">
    <neighbourhoodSize class="controlparameters.ConstantControlParameter">
      <parameter value="3" />
    </neighbourhoodSize>
  </topology>
</algorithm>

As a result the properties can be set either as sub elements or as
attributes, with the exception of objects that need to be instantiated.

I hope this clears it up :)

Regards,
Gary
