public boolean matchesFamily(byte[] table, byte[] family, Permission.Action action)
true
if this permission matches the given column
family at least. This only indicates a partial match against the table
and column family, however, and does not guarantee that implies() for the
column same family would return true
. In the case of a
column-qualifier specific permission, for example, implies() would still
return false.public boolean matchesFamilyQualifier(byte[] table, byte[] family, byte[] qualifier, Permission.Action action)
