Constructor Detail

SingletonProxyTrustIterator

public SingletonProxyTrustIterator(Object obj)

Creates an instance with the specified object to use as the only element of the iteration.

Parameters:

obj - the object to use as the element of the iteration

Throws:

NullPointerException - if the argument is null

Method Detail

hasNext

public boolean hasNext()

Description copied from interface: ProxyTrustIterator

Returns true if the iteration has more elements, and false otherwise.

Specified by:

hasNext in interface ProxyTrustIterator

Returns:

true if the iteration has more elements, and false otherwise

next

public Object next()

Description copied from interface: ProxyTrustIterator

Returns the next element in the iteration. This method can throw an exception (other than NoSuchElementException) without terminating the iteration.

Specified by:

next in interface ProxyTrustIterator

Returns:

the next element in the iteration

Throws:

NoSuchElementException - if the iteration has no more elements

setException

public void setException(RemoteException e)

Description copied from interface: ProxyTrustIterator

Provides the iteration with a RemoteException thrown from a remote call made while attempting to obtain a TrustVerifier from the object returned by the most recent call to next. Setting an exception may influence which (if any) elements are subsequently produced by the iteration. (A RemoteException thrown directly by next should not be passed to this method.)

Specified by:

setException in interface ProxyTrustIterator

Parameters:

e - RemoteException thrown from a remote call

Throws:

NullPointerException - if the argument is null

IllegalStateException - if next has never been called, or if this method has already been called since the most recent call to next, or if hasNext has been called since the most recent call to next, or if the most recent call to next threw a RemoteException
