Constructor Detail

ServerIterator

public ServerIterator(RangeIterator iterator,
                      RemoteAdapterFactory factory,
                      int maxBufferSize)
               throws RemoteException

Deprecated.

Creates a remote adapter for the given local item.

Parameters:

iterator - local iterator to be adapted

factory - remote adapter factory

maxBufferSize - maximum buffer size

Throws:

RemoteException - on RMI errors

Method Detail

getSize

public long getSize()
             throws RemoteException

Deprecated.

Returns the size of the iterator. The size is cached by invoking the adapted local iterator when this method is first called or by determining the size from an end-of-iterator condition in nextObjects().

Specified by:

getSize in interface RemoteIterator

Returns:

size of the iterator

Throws:

RemoteException - on RMI errors

See Also:

RangeIterator.getSize()

skip

public void skip(long items)
          throws NoSuchElementException,
                 RemoteException

Deprecated.

Skips the given number of elements.

Specified by:

skip in interface RemoteIterator

Parameters:

items - number of elements to skip

Throws:

NoSuchElementException - if skipped past the last element

RemoteException - on RMI errors

See Also:

RangeIterator.skip(long)

getRemoteObject

protected abstract Object getRemoteObject(Object object)
                                   throws RemoteException

Deprecated.

Returns a remote adapter for the given local object. This abstract method is used by nextObjects() to convert the local objects to remote references to be sent to the client.

Subclasses should implement this method to use the remote adapter factory to create remote adapters of the specific element type.

Parameters:

object - local object

Returns:

remote adapter

Throws:

RemoteException - on RMI errors

nextObjects

public Object[] nextObjects()
                     throws RemoteException

Deprecated.

Returns an array of remote references to the next elements in this iteration.

Specified by:

nextObjects in interface RemoteIterator

Returns:

array of remote references, or null

Throws:

RemoteException - on RMI errors

Iterator.next()
