public interface IScanListIterator<T> extends IObjectsList
IScanListIterator defines the interface for the result of stored-lists/extended indexes matching

  • Method Details

    • hasNext

      boolean hasNext() throws SAException
      Throws:
      SAException

    • next

      T next() throws SAException
      Throws:
      SAException

    • releaseScan

      void releaseScan() throws SAException
      release SLHolder for this scan
      Throws:
      SAException

    • getAlreadyMatchedFixedPropertyIndexPos

      int getAlreadyMatchedFixedPropertyIndexPos()
      if the scan is on a property index, currently supported for extended index

    • getAlreadyMatchedIndexPath

      default String getAlreadyMatchedIndexPath()

    • isAlreadyMatched

      boolean isAlreadyMatched()
      is the entry returned already matched against the searching template currently is true if the underlying scan made by CacheManager::EntriesIter

    • isExtensionIndex

      default boolean isExtensionIndex()
      Returns:
      true if this iterator is QueryExtensionIndexEntryIteratorWrapper

    • isMultiListsIterator

      default boolean isMultiListsIterator()
      does this iter contain multiple lists

    • noRematchNeeded

      default boolean noRematchNeeded()

    • createCopyForAlternatingThread

      default IScanListIterator createCopyForAlternatingThread()
      create a shallow copy ready for alternating thread usage
      Returns:
      a new shallow copyed IScanListIterator ready for alternating thread usage NOTE!! should be called before first hasNext() call

    • hasSize

      default boolean hasSize()
      Returns:
      true if the iterator knows its size, and size() can be called.

    • size

      default int size()
