Like all OsidLists, SystemNodeList provides a means for accessing SystemNode elements sequentially either one at a time or many at a time. Examples:

while (snl.hasNext()) {
     SystemNode node = snl.getNextSystemNode();
}
                

while (snl.hasNext()) {
     SystemNode[] nodes = snl.getNextSystemNodes(snl.available());
}
                

Like all OsidLists, SystemNodeList is stateful and must not be accessed by multiple processing threads.
