Interface ConnectionFactoryFilter<ResolvedAddress,C extends ListenableAsyncCloseable>

Type Parameters:

ResolvedAddress - The type of a resolved address that can be used for connecting.

C - The type of connections created by the ConnectionFactory decorated by this filter.

All Known Implementing Classes:

LimitingConnectionFactoryFilter

Functional Interface:

This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.

@FunctionalInterface
public interface ConnectionFactoryFilter<ResolvedAddress,C extends ListenableAsyncCloseable>

A contract to decorate ConnectionFactory instances for the purpose of filtering.

Method Summary

Modifier and Type	Method and Description
default ConnectionFactoryFilter<ResolvedAddress,C>	append(ConnectionFactoryFilter<ResolvedAddress,C> before) Returns a composed function that first applies the before function to its input, and then applies this function to the result.
ConnectionFactory<ResolvedAddress,C>	create(ConnectionFactory<ResolvedAddress,C> original) Decorates the passed original ConnectionFactory to add the filtering logic.
static <ResolvedAddress,C extends ListenableAsyncCloseable> ConnectionFactoryFilter<ResolvedAddress,C>	identity() Returns a function that always returns its input ConnectionFactory.

Method Detail

create

ConnectionFactory<ResolvedAddress,C> create(ConnectionFactory<ResolvedAddress,C> original)

Decorates the passed original ConnectionFactory to add the filtering logic.

Parameters:

original - ConnectionFactory to filter.

Returns:

Decorated ConnectionFactory that contains the filtering logic.

append

default ConnectionFactoryFilter<ResolvedAddress,C> append(ConnectionFactoryFilter<ResolvedAddress,C> before)

Returns a composed function that first applies the before function to its input, and then applies this function to the result.

The order of execution of these filters are in order of append. If 3 filters are added as follows:

     builder.append(filter1).append(filter2).append(filter3)
 

Calling ConnectionFactory wrapped by this filter chain, the order of invocation of these filters will be:

     filter1 => filter2 => filter3 => original connection factory
 

Parameters:

before - the function to apply before this function is applied

Returns:

a composed function that first applies the before function and then applies this function.

identity

static <ResolvedAddress,C extends ListenableAsyncCloseable> ConnectionFactoryFilter<ResolvedAddress,C> identity()

Returns a function that always returns its input ConnectionFactory.

Type Parameters:

ResolvedAddress - The type of a resolved address that can be used for connecting.

C - The type of connections created by the ConnectionFactory decorated by this filter.

Returns:

a function that always returns its input ConnectionFactory.
