Detailed Description

When iterating the table fields for sometimes you want to skip some columns.

Such a case is the filtering of GIPK or functional indexes when replicating a table.

Classes that inherit this class shall also implement the method

static bool is_filter_needed(THD const *thd, TABLE *table, table_def const *tabledef);

It allows for the conditional addition of the filter only when it makes sense
