Interface IHeapObjectArgument

  • All Superinterfaces:
    Iterable<int[]>

    public interface IHeapObjectArgument
    extends Iterable<int[]>
    An argument of type IHeapObjectArgument can be used to inject heap objects into Query.
     @Argument
     public IHeapObjectArgument objects;
     
     public IResult execute(IProgressListener listener) throws Exception
     {
         for (int[] objectIds : objects)
         {
             for (int objectId : objectIds)
             {
                 // do something
             }
         }
     }
     

    There are two advantages over using primitive Integer arrays: First, the object set is chunked (if accessed through the iterator) and second, there is no need to annotate the variable with isHeapObject = true.

     @Argument(isHeapObject = true)
     public int[] objects;

      • getIds

        int[] getIds​(IProgressListener listener)
              throws SnapshotException
        This method returns one (possibly big) integer array with the selected object ids. This method can be much slower than the approach described in the class documentation.
        Parameters:
        listener - progress listener
        Returns:
        an integer array with the selected object ids
        Throws:
        SnapshotException
      • getLabel

        String getLabel()
        A user-friendly label for the object set.
