/**
* A uniform interface for invoking HTTP requests.
* <p>
* Any Java type for a response entity, that is supported by the client
* configuration of the client, may be declared using
* <code>Class<T></code> where <code>T</code> is the Java type, or
* using {@link GenericType} where the generic parameter is the Java type.
* <p>
* Any Java type instance for a request entity, that is supported by the client
* configuration of the client, can be passed. If generic information is
* required then an instance of {@link javax.ws.rs.core.GenericEntity} may
* be used.
* <p>
* A type of {@link ClientResponse} declared
* for the response entity may be used to obtain the status, headers and
* response entity.
* <p>
* If any type, other than {@link ClientResponse},
* is declared and the response status is greater than or equal to 300 then a
* {@link UniformInterfaceException} exception
* will be thrown, from which the
* {@link ClientResponse} instance can be
* accessed.
* <p>
* In the following cases it is necessary to close the response, when response
* processing has completed, to ensure that underlying resources are
* correctly released.
* <p>
* If a response entity is declared of the type
* {@link ClientResponse}
* or of a type that is assignable to {@link java.io.Closeable}
* (such as {@link java.io.InputStream}) then the response must be either:
* 1) closed by invoking the method
* {@link ClientResponse#close() } or
* {@link java.io.Closeable#close}; or 2) all bytes of response entity must be
* read.
* <p>
* If a {@link UniformInterfaceException} is
* thrown then by default the response entity is automatically buffered and
* the underlying resources are correctly released. See the following property
* for more details:
* {@link ClientConfig#PROPERTY_BUFFER_RESPONSE_ENTITY_ON_EXCEPTION}.
