Examples of net.jini.jeri.BasicObjectEndpoint.newCall()

net.jini.jeri.BasicObjectEndpoint.newCall()
{@inheritDoc}
This method first invokes {@link Endpoint#newRequest newRequest} on this BasicObjectEndpoint'scontained Endpoint with the specified constraints to obtain an OutboundRequestIterator. It then wraps the obtained iterator in another OutboundRequestIterator and returns the wrapped iterator.
The methods of the returned OutboundRequestIterator behave as follows:
{@link OutboundRequestIterator#hasNext boolean hasNext()}:

Returns true if this iterator supports making at least one more attempt to communicate the remote call, and false otherwise.
This method invokes hasNext on the underlying iterator and returns the result.
The security context in which this method is invoked may be used for subsequent verification of security permissions; see the {@link OutboundRequestIterator#next next} methodspecification for more details.

{@link OutboundRequestIterator#next OutboundRequest next()}:

Initiates an attempt to communicate the remote call to the referenced remote object.
This method invokes next on the underlying iterator to obtain an OutboundRequest. Then it writes the object identifier of the BasicObjectEndpoint that produced this iterator to the request's output stream by invoking {@link Uuid#write(OutputStream) Uuid.write(OutputStream)} with therequest output stream, and then it returns the request.
Throws {@link NoSuchElementException} if this iterator doesnot support making another attempt to communicate the remote call (that is, if hasNext would return false).
Throws {@link IOException} if an IOException isthrown by the invocation of next on the underlying iterator or by the subsequent I/O operations.
Throws {@link SecurityException} if aSecurityException is thrown by the invocation of next on the underlying iterator or by the subsequent I/O operations.
@throws NullPointerException {@inheritDoc}
