/**
|
|
* This interface is used by iterators that use releasable resources during iteration.
|
|
*
|
|
* The consumer of a CloseableIterator should ensure that the close() method is always called,
|
|
* for example by putting such a call in a finally block. Two conventions should be followed
|
|
* by all implementors of CloseableIterator:
|
|
* 1) The close() method should be idempotent. Calling close() twice should have no effect.
|
|
* 2) When hasNext() returns false, the iterator implementation should automatically close itself.
|
|
* The latter makes it somewhat safer for consumers to use the for loop syntax for iteration:
|
|
* for (Type obj : getCloseableIterator()) { ... }
|
|
*
|
|
* We do not inherit from java.io.Closeable because IOExceptions are a pain to deal with.
