MatrixCursor.RowBuilder
public class MatrixCursor.RowBuilder
extends Object
Builds a row of values using either of these approaches:
- Values can be added with explicit column ordering using
add(Object)
, which starts from the left-most column and adds one column value at a time. This follows the same ordering as the column names specified at cursor construction time.
- Column and value pairs can be offered for possible inclusion using
add(String, Object)
. If the cursor includes the given column, the value will be set for that column, otherwise the value is ignored. This approach is useful when matching data to a custom projection.
Undefined values are left as
null
.
