Package javax.ws.rs.client
Interface Client
- All Superinterfaces:
Configurable<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
Client
instance
may be a rather expensive operation. It is therefore advised to construct only
a small number of Client
instances in the application. Client instances
must be properly closed
before being disposed to avoid leaking
resources.- Since:
- 2.0

Method Details

close
void close()Close client instance and all it's associated resources. Subsequent calls have no effect and are ignored. Once the client is closed, invoking any other method on the client instance would result in anIllegalStateException
being thrown. Calling this method effectively invalidates allresource targets
produced by the client instance. Invoking any method on such targets once the client is closed would result in anIllegalStateException
being thrown. -
