Interface MiExtractorCallback

public interface MiExtractorCallback

Base interface for extraction callback interfaces.

This interface specifies the methods used by extractors to notify the application when an extraction starts and stops.

Method Summary

Modifier and Type	Method and Description
void	beginCallback(boolean geomChanged, boolean topoChanged, boolean dataSetChanged) This method is called each time a new extraction starts and only if the mesh, the cell filter, the tessellator or the data sets have changed since the last extraction.
void	endCallback(boolean geomChanged, boolean topoChanged, boolean dataSetChanged) This method is called each time a new extraction ends and only if the mesh, the cell filters, the tessellator or the data sets have changed since the last extraction.

Method Detail

beginCallback

void beginCallback(boolean geomChanged,
                   boolean topoChanged,
                   boolean dataSetChanged)

This method is called each time a new extraction starts and only if the mesh, the cell filter, the tessellator or the data sets have changed since the last extraction.

Parameters:

geomChanged - true if the geometry of the extracted mesh must be updated

topoChanged - true if the topology of the extracted mesh must be updated

dataSetChanged - true if the data sets associated to the extracted mesh must be updated

endCallback

void endCallback(boolean geomChanged,
                 boolean topoChanged,
                 boolean dataSetChanged)

This method is called each time a new extraction ends and only if the mesh, the cell filters, the tessellator or the data sets have changed since the last extraction. After this call, the extracted mesh has been updated and can then be parsed again to retrieve the new values.

Parameters:

geomChanged - true if the geometry of the extracted mesh has just been updated

topoChanged - true if the topology of the extracted mesh has just been updated

dataSetChanged - true if the data sets associated to the extracted mesh has just been updated
