◆ getDataLayout()

virtual AddInfoLayoutHandle getDataLayout ( ) const
pure virtual

Get the attribute layout of the data that will be returned by the import object.

The returned layout is merged from the provided layout during import object creation and the actual import attribute layout. For import classes that provide configurable attribute import, the layout can only be access AFTER prepareForReading was called, since there the actual data layout is typcially constructed.

◆ getPrecision()

virtual void getPrecision ( double &  precX,
double &  precY,
double &  precZ 
) const
pure virtual

The 'epsilon' of coordinates (e.g. coordinates with mm-precision: 0.001) Relevant only for ASCII files.
