Package com.google.javascript.jscomp

Class Es6ConvertSuper

java.lang.Object
com.google.javascript.jscomp.NodeTraversal.AbstractPostOrderCallback
com.google.javascript.jscomp.Es6ConvertSuper
All Implemented Interfaces:
CompilerPass, NodeTraversal.Callback
public final class Es6ConvertSuper extends NodeTraversal.AbstractPostOrderCallback implements CompilerPass
Converts super.method() calls and adds constructors to any classes that lack them.

This has to run before the main Es6RewriteClass pass. The super() constructor calls are not converted here, but rather in Es6ConvertSuperConstructorCalls, which runs later.

    • visit

      public void visit(NodeTraversal t, Node n, Node parent)
      Description copied from interface: NodeTraversal.Callback
      Visits a node in postorder (after its children). A node is visited in postorder iff NodeTraversal.Callback.shouldTraverse(NodeTraversal, Node, Node) returned true for its parent and itself. In particular, the root node is never visited in postorder.

      Siblings are always visited left-to-right.

      Implementations can have side-effects (e.g. modify the parse tree). Removing the current node is legal, but removing or reordering nodes above the current node may cause nodes to be visited twice or not at all.

      Specified by:
      visit in interface NodeTraversal.Callback
      Parameters:
      t - The current traversal.
      n - The current node.
      parent - The parent of the current node.

    • process

      public void process(Node externs, Node root)
      Description copied from interface: CompilerPass
      Process the JS with root node root. Can modify the contents of each Node tree
      Specified by:
      process in interface CompilerPass
      Parameters:
      externs - Top of external JS tree
      root - Top of JS tree
