public class ChainedFilter extends Filter
Allows multiple Filter
s to be chained.
Logical operations such as NOT and XOR
are applied between filters. One operation can be used
for all filters, or a specific operation can be declared
for each filter.
Order in which filters are called depends on the position of the filter in the chain. It's probably more efficient to place the most restrictive filters /least computationally-intensive filters first.
