Class Client

java.lang.Object
  com.sun.jersey.api.client.filter.Filterable
      com.sun.jersey.api.client.Client

All Implemented Interfaces:

ClientHandler

public class Client
extends Filterable
implements ClientHandler

The main class for creating WebResource instances and configuring the properties of connections and requests.

ClientFilter instances may be added to the client for filtering requests and responses, including those of WebResource instances created from the client.

A client may be configured by passing a ClientConfig instance to the appropriate constructor.

Methods to create instances of WebResource are thread-safe. Methods that modify configuration and or filters are not guaranteed to be thread-safe.

The creation of a Client instance is an expensive operation and the instance may make use of and retain many resources. It is therefore recommended that a Client instance is reused for the creation of WebResource instances that require the same configuration settings.

A client may integrate with an IoC framework by passing a IoCComponentProviderFactory instance to the appropriate constructor.
