convert
Deprecated.Converts a source type object to a target type object. -
hasNext
Deprecated.Checks whether the source type iteration contains more elements.- Returns:
- true if the source type iteration contains more elements, false otherwise.
- Throws:
X
-
next
Deprecated.Returns the next element from the source type iteration.- Returns:
- the next element in the iteration.
- Throws:
XNoSuchElementException- If all elements have been returned.IllegalStateException- If the iteration has been closed.
-
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().X extends Exception

handleClose
Deprecated.Closes this iteration as well as the wrapped iteration if it is aCloseableIteration.- Overrides:
