InheritanceLabelOutputHandler Inheritance AbstractOutputHandler

An IOutputHandler implementation that writes labels for graph objects.

The resulting output has the following format:

     <y:Labels>

          <y:Label>

            <y:Style_Of_Label_1>

                ...
            </y:Style_Of_Label_1>

            <Additional parameters/>

             ....
            <Additional parameters/> 
             Text of Label 1
           </y:Label>
      ...
           <y:Label>
            <y:Style_Of_Label_N>
                ...
            </y:Style_Of_Label_N>
           <Additional parameters/>
             ....
           <Additional parameters/>
             Text of Label n
           </y:Label>
        </y:Labels>
