    Methods

    hasGlobalName? isEmitNotificationEnabled? onEmitNode? substituteNode?

    Methods

    • A hook used by the Printer when generating unique names to avoid collisions with globally defined names that exist outside of the current source file.

      Parameters

      • name: string

      Returns boolean

    • A hook used to check if an emit notification is required for a node.

      Parameters

      Returns boolean

    • A hook used by the Printer to provide notifications prior to emitting a node. A compatible implementation must invoke emitCallback with the provided hint and node values.

      Parameters

      • hint: tsc.EmitHint

        A hint indicating the intended purpose of the node.

      • node: tsc.Node

        The node to emit.

      • emitCallback: (hint: tsc.EmitHint, node: tsc.Node) => void

        A callback that, when invoked, will emit the node.

      Returns void

      var printer = createPrinter(printerOptions, {
        onEmitNode(hint, node, emitCallback) {
          // set up or track state prior to emitting the node...
          emitCallback(hint, node);
          // restore state after emitting the node...
        }
      });

    • A hook used by the Printer to perform just-in-time substitution of a node. This is primarily used by node transformations that need to substitute one node for another, such as replacing myExportedVar with exports.myExportedVar.

      Parameters

      • hint: tsc.EmitHint

        A hint indicating the intended purpose of the node.

      • node: tsc.Node

        The node to emit.

      Returns tsc.Node

      var printer = createPrinter(printerOptions, {
        substituteNode(hint, node) {
          // perform substitution if necessary...
          return node;
        }
      });
