getInstance

static Tables.ColumnNameFilter getInstance(String fullyQualifiedColumnNames)

Build the Tables.ColumnNameFilter that determines whether a column identified by a given ColumnId is to be included, using the given comma-separated regular expression patterns defining which columns (if any) should be excluded.

Note that this predicate is completely independent of the table selection predicate, so it is expected that this predicate be used only after the table selection predicate determined the table containing the column(s) is to be used.
