Interface Endpoint

All Known Implementing Classes:

HttpEndpoint, HttpsEndpoint, KerberosEndpoint, SslEndpoint, TcpEndpoint

public interface Endpoint

Represents a remote communication endpoint to send requests to.

An Endpoint instance contains the information necessary to send requests to the remote endpoint. For example, a TCP-based Endpoint implementation typically contains the remote host address and TCP port to connect to.

The newRequest method can be used to send a request to the remote endpoint that this object represents.

An instance of this interface should be serializable and should implement Object.equals to return true if and only if the argument is equivalent to the instance in trust, content, and function. That is, the equals method should be a sufficient substitute for TrustEquivalence.checkTrustEquivalence. But unlike checkTrustEquivalence, the equals method cannot assume that the implementations of any of the invoked instance's pluggable component objects are trusted (whether pluggable through public APIs or deserialization). Therefore, the equals method should not invoke comparison methods (such as equals) on any such component without first verifying that the component's implementation is at least as trusted as the implementation of the corresponding component in the equals argument (such as by verifying that the corresponding component objects have the same actual class). If any such verification fails, the equals method should return false without invoking a comparison method on the component. Furthermore, these guidelines should be recursively obeyed by the comparison methods of each such component for its subcomponents.

If an Endpoint is an instance of TrustEquivalence, then its equals method must obey the above guidelines and its checkTrustEquivalence method must not return true if its equals method would not return true for the same argument.

All aspects of the underlying communication mechanism that are not specified here are defined by the particular implementation of this interface.

Method Detail

newRequest

OutboundRequestIterator newRequest(InvocationConstraints constraints)

Returns an OutboundRequestIterator to use to send a new request to this remote endpoint using the specified constraints.

The constraints must be the complete, absolute constraints for the request.

Parameters:

constraints - the complete, absolute constraints

Returns:

an OutboundRequestIterator to use to send a new request to this remote endpoint

Throws:

NullPointerException - if constraints is null
