                      java.lang.String tablename)
               throws FormatException

Construct a PrimitiveTable.

Parameters:

cov - the coverage table that is our "parent"

tile - the tile for the table

tablename - must be a 3 character VPF tablename

Throws:

FormatException - if something goes wrong opening the file

Method Detail
