    Similar to mapOperation, but only visiting instead of copying and transforming explicitly. e.g.:

    visitOperation({
      type: Algebra.Types.DISTINCT,
      input: {
        type: Algebra.Types.PROJECT,
        input: { type: Algebra.Types.DISTINCT },
      },
    }, {
      [Algebra.Types.DISTINCT]: { visitor: () => console.log('1') },
      [Algebra.Types.PROJECT]: {
        preVisitor: () => ({ continue: false }),
        visitor: () => console.log('2'),
      },
    });

    Will first call the preVisitor on the project and notice it should not iterate on its descendants. It then visits the project, and the outermost distinct, printing '21'. The pre-visitor visits starting from the root, going deeper, while the actual visitor goes in reverse.

      • Visit a selected subTree given a startObject, steering the visits based on Typed nodes. Will first call the preVisitor on the project and notice it should not iterate on its descendants. It then visits the project, and the outermost distinct, printing '21'. The pre-visitor visits starting from the root, going deeper, while the actual visitor goes in reverse.

        Parameters

          the object from which we will start visiting, potentially visiting its descendants along the way.

          a dictionary mapping the various operation types to objects optionally containing preVisitor and visitor. The preVisitor allows you to provide VisitContext for the current object, altering how it will be visited. The visitor allows you to visit the object from deepest to the outermost object. This is useful if you for example want to manipulate the objects you visit during your visits, similar to this.transformNode.

    the object from which we will start visiting, potentially visiting its descendants along the way.
