/**

* This class is a default parameter container for geometry operation.<br>
|
31 |
*
|
32 |
* Normally every GeometryOperation will extend this class and identify
|
33 |
* its parameters publicly with getters/setters
|
34 |
*
|
35 |
* For those operations that need high performance, parameters should be declared as class
|
36 |
* members instead of using the setAttribute/getAttribute mechanism. This way you avoid a hash
|
37 |
* and a cast operation.
