bool te::vp::MakeGeometryValid::makeValid ( const te::da::DataSourcePtr  dataSource,
const std::string &  dataSetName,
std::string &  errorMessage,
te::da::ObjectIdSet *  oidSet = 0 
)
static

This method gets the datasource capabilities and calls the specific function to fix geometry.

Parameters
dataSourceThe data source information.
dataSetNameThe input data name.
errorMessageVariable to catch any error occurred during execution.
oidSetSet of object ids to filter iconsistent geometries.
Returns
True, if the function was executed successfully and the geometries fixed was updated.

const std::string &  dataSetName,
std::string &  errorMessage,
te::da::ObjectIdSet *  oidSet = 0 
)
staticprivate

It tries to fix invalid geometry by SQL clause ST_MakeValid and updates the source data.

Parameters
dataSourceThe data source information.
dataSetNameThe input data name.
errorMessageVariable to catch any error occurred during execution.
Returns
True, if the query was executed successfully and the geometries fixed was updated.
Note
The layer must be inserted in a database with spatial extent.
