Examples of javax.ws.rs.client.Client

javax.ws.rs.client.Client
Client is the main entry point to the fluent API used to build and execute client requests in order to consume responses returned.
Clients are heavy-weight objects that manage the client-side communication infrastructure. Initialization as well as disposal of a {@code Client} instancemay be a rather expensive operation. It is therefore advised to construct only a small number of {@code Client} instances in the application. Client instancesmust be {@link #close() properly closed} before being disposed to avoid leakingresources. @author Marek Potociar @see javax.ws.rs.core.Configurable @since 2.0
