Description copied from interface: ValueWriter

Write value to a vector as a Java object of the "native" type for the column. This form is available only on scalar writers. The object must be of the form for the primary write method above.

Primarily to be used when the code already knows the object type.

Parameters:

value - a value that matches the primary setter above, or null to set the column to null
