Class Es6RewriteBlockScopedFunctionDeclaration

java.lang.Object
com.google.javascript.jscomp.NodeTraversal.AbstractPostOrderCallback
com.google.javascript.jscomp.Es6RewriteBlockScopedFunctionDeclaration
All Implemented Interfaces:
CompilerPass, NodeTraversal.Callback
public final class Es6RewriteBlockScopedFunctionDeclaration extends NodeTraversal.AbstractPostOrderCallback implements CompilerPass
Rewrite block-scoped function declarations as "let"s. This pass must happen before Es6RewriteBlockScopedDeclaration, which rewrites "let" to "var".

  • Method Details

    • 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

    • 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.
