inherited

It sets the input parameters that will be consumed to execute the operation.

Parameters

distance	A numeric value to set a fixed distance to buffer.
bufferPolygonRule	The rule used for buffer result (INSIDE_OUTSIDE = 0, ONLY_OUTSIDE = 1, ONLY_INSIDE = 2).
bufferBoundariesRule	The BoundariesBetweenBuffers can be dissolved or not - (DISSOLVE = 0 and NOT_DISSOLVE = 1).
copyInputColumns	Copy columns from input DataSet.
levels	The number of levels buffer will have.
attributePosition	The buffer can be calculated by attribute values. The attribute must be numeric type.

Note: If uses attibutePosition parameter, the fixed distance will be ignored.; The attributePosition parameter must be numeric type.; If there is a null value or zero in chosen attribute, the line that has this value will be ignored.
