    • put

      public void put(long index, Object array, int ioff, int count)
      Description copied from interface: ValueStore
      Stores a vector of values in this object. array must be an array of values matching getType. Element ioff of array is stored at index index, elemnt ioff+1 at index+1, etc.
      Specified by:
      put in interface ValueStore
      Parameters:
      index - starting offset to write to
      array - array of values to store
      ioff - offset into array from which the first value is taken
      count - number of values to transfer
    • get

      public void get(long index, Object array, int ioff, int count)
      Description copied from interface: ValueStore
      Retrieves a vector of values from this object. array must be an array of type matching getType. Every element of array will be filled with values; the first retrieved from offset index, the second from index+1, etc.
      Specified by:
      get in interface ValueStore
      Parameters:
      index - starting offset
      array - array to accept data
      ioff - offset into array to which the first value is copied
