class |
AbstractCloseableIteration<E,X extends Exception>

CloseableIterations offering common functionality. |
class |

Deprecated.
since 4.0. Use
AbstractCloseableIteration instead. |
class |

An Iteration that can convert an
Iterator to a CloseableIteration. |
class |
ConvertingIteration<S,T,X extends Exception>

iteration over objects of type T (the target type).
|
class |
DelayedIteration<E,X extends Exception>

|
class |

|
class |

An iterator that does not contain any elements.
|
class |
ExceptionConvertingIteration<E,X extends Exception>

X.
|
class |
FilterIteration<E,X extends Exception>

LookAheadIteration.hasNext(). |
class |

Iteration (the right argument).
|
class |
OffsetIteration<E,X extends Exception>
An Iteration that skips the first offset elements from an underlying Iteration.
|
class |
QueueIteration<E,T extends Exception>
Makes working with a queue easier by adding the methods
QueueIteration.done() and QueueIteration.toss(Exception) and
after converting the Exception to the required type using QueueIteration.convert(Exception). |

Removes consecutive duplicates from the object stream.
|
class |

class |
UnionIteration<E,X extends Exception>
An Iteration that returns the bag union of the results of a number of Iterations.
