Method Detail

defineCharacteristics

public void defineCharacteristics()

Description copied from class: es.unex.sextante.core.GeoAlgorithm

This method should be overridden and used to specify the parameters needed by the GeoAlgorithm, using the corresponding methods of the ParametersSet object. Also, output objects must be added, so SEXTANTE knows in advance which outputs will be generated by the algorithm. See the addOutputXXXX family of methods (GeoAlgorithm.addOutputRasterLayer(java.lang.String, java.lang.String, int, es.unex.sextante.outputs.IOutputChannel, es.unex.sextante.dataObjects.IRasterLayer), GeoAlgorithm.addOutputVectorLayer(java.lang.String, java.lang.String, int, es.unex.sextante.outputs.IOutputChannel, es.unex.sextante.dataObjects.IVectorLayer, java.lang.String, int), etc.)

Specified by:

defineCharacteristics in class es.unex.sextante.core.GeoAlgorithm

processAlgorithm

public boolean processAlgorithm()
                         throws es.unex.sextante.exceptions.GeoAlgorithmExecutionException

Description copied from class: es.unex.sextante.core.GeoAlgorithm

This method should implement the algorithm itself, using the values of the parameters and processing them.

Specified by:

processAlgorithm in class es.unex.sextante.core.GeoAlgorithm

Returns:

true if the algorithm was correctly executed. False if it was canceled.

Throws:

es.unex.sextante.exceptions.GeoAlgorithmExecutionException - if there were problems during algorithm execution
