Class CloseableIterable<T>

java.lang.Object
  com.alexkasko.springjdbc.iterable.CloseableIterable<T>

All Implemented Interfaces:

Closeable, Iterable<T>

public abstract class CloseableIterable<T>
extends Object
implements Iterable<T>, Closeable

Specialized Iterable partial implementation, returns closable iterators. This class is not used directly in this library and may be used for processing possible results for multiple queries in "passive" mode (no DB resources are used until client call to iterator()). Retains references to returned iterators and closes them on close() call.
