ConvertingIteration
protected ConvertingIteration(CloseableIteration<? extends S> iter)
Deprecated.Creates a new ConvertingIteration that operates on the supplied source type iteration.- Parameters:
iter- The source type iteration for this ConvertingIteration, must not be null.
-
-
Method Detail
-
convert
protected abstract T convert(S sourceObject)
Deprecated.Converts a source type object to a target type object.
-
hasNext
public boolean hasNext()
Deprecated.Checks whether the source type iteration contains more elements.- Returns:
- true if the source type iteration contains more elements, false otherwise.
-
next
public T next()
Deprecated.Returns the next element from the source type iteration.- Throws:
NoSuchElementException- If all elements have been returned.IllegalStateException- If the iteration has been closed.
-
remove
public void remove()
Deprecated.Calls remove() on the underlying Iteration.- Throws:
UnsupportedOperationException- If the wrapped Iteration does not support the remove operation.IllegalStateException- If the Iteration has been closed, or ifnext()has not yet been called, orremove()has already been called after the last call tonext().
-
handleClose
protected void handleClose()
Deprecated.Closes this iteration as well as the wrapped iteration if it is aCloseableIteration.- Overrides:
