Package com.vladsch.flexmark.experimental.util.collection.iteration

Class PositionListBase<T,​P extends IPositionHolder<T,​P>>

  • Type Parameters:
    T - type of position
    P - type of position holder
    All Implemented Interfaces:
    IPositionListener, IPositionUpdater<T,​P>, IPreviewPositionListener, java.lang.Iterable<P>
    Direct Known Subclasses:
    PositionList
    public abstract class PositionListBase<T,​P extends IPositionHolder<T,​P>>
extends java.lang.Object
implements java.lang.Iterable<P>, IPositionUpdater<T,​P>
    Iterator for list positions allowing to iterate over current elements while inserting and deleting elements relative to current position

    elements inserted at current position or at current + 1 position will skipped in the iteration allowing adding new elements which will not be part of the iteration
