Class Filters.FamilyFilter (2.34.0)

Matches only cells from columns whose families match the value.

Matches only cells from columns whose families satisfy the given RE2 regex. For technical reasons, the regex must not contain the : character, even if it is not being used as a literal. Note that, since column families cannot contain the new line character , it is sufficient to use . as a full wildcard when matching column family names.
