  • Method Details

    • get

      List<V> get(int... indexes)
      Loads elements by specified indexes
      Parameters:
      indexes - of elements
      Returns:
      list of elements

    • distributedIterator

      Iterator<V> distributedIterator(int count)
      Returns element iterator that can be shared across multiple applications. Creating multiple iterators on the same object with this method will result in a single shared iterator. See distributedIterator(String, int) for creating different iterators.
      Parameters:
      count - batch size
      Returns:
      shared elements iterator

    • distributedIterator

      Iterator<V> distributedIterator(String iteratorName, int count)
      Returns iterator over elements that match specified pattern. Iterator can be shared across multiple applications. Creating multiple iterators on the same object with this method will result in a single shared iterator. Iterator name must be resolved to the same hash slot as list name.
      Parameters:
      iteratorName - redis object name to which cursor will be saved
      count - batch size
      Returns:
      shared elements iterator

    • mapReduce

      <KOut, VOut> RCollectionMapReduce<V,KOut,VOut> mapReduce()
      Returns RMapReduce object associated with this map
      Type Parameters:
      KOut - output key
      VOut - output value
      Returns:
      MapReduce instance

    • addAfter

      int addAfter(V elementToFind, V element)
      Add element after elementToFind
      Parameters:
      elementToFind - - object to find
      element - - object to add
      Returns:
      new list size

    • addBefore

      int addBefore(V elementToFind, V element)
      Add element before elementToFind
      Parameters:
      elementToFind - - object to find
      element - - object to add
      Returns:
      new list size

    • fastSet

      void fastSet(int index, V element)
      Set element at index. Works faster than List.set(int, Object) but doesn't return previous element.
      Parameters:
      index - - index of object
      element - - object to set

    • subList

      RList<V> subList(int fromIndex, int toIndex)
      Specified by:
      subList in interface List<V>

    • readAll

      List<V> readAll()
      Read all elements at once
      Returns:
      list of values

    • trim

      void trim(int fromIndex, int toIndex)
      Trim list and remains elements only in specified range fromIndex, inclusive, and toIndex, inclusive.
      Parameters:
      fromIndex - - from index
      toIndex - - to index

    • range

      List<V> range(int toIndex)
      Returns range of values from 0 index to toIndex. Indexes are zero based. -1 means the last element, -2 means penultimate and so on.
      Parameters:
      toIndex - - end index
      Returns:
      elements

    • range

      List<V> range(int fromIndex, int toIndex)
      Returns range of values from fromIndex to toIndex index including. Indexes are zero based. -1 means the last element, -2 means penultimate and so on.
      Parameters:
      fromIndex - - start index
      toIndex - - end index
      Returns:
      elements

    • fastRemove

      void fastRemove(int index)
      Remove object by specified index
      Parameters:
      index - - index of object

    • remove

      boolean remove(Object element, int count)
      Removes up to count occurrences of element
      Parameters:
      element - - element to find
      count - - amount occurrences
      Returns:
      true if at least one element removed; or false if element isn't found

    • addListener

      int addListener(ObjectListener listener)
      Adds object event listener
      Specified by:
      addListener in interface RObject
      Parameters:
      listener - - object event listener
      Returns:
      listener id
