    • execute

      public Object execute(com.oracle.truffle.api.frame.VirtualFrame frame)
      Description copied from class: JavaScriptNode
      Executes this node using the specified context and frame and returns the result value.
      Specified by:
      execute in class JavaScriptNode

    • executeInt

      public int executeInt(com.oracle.truffle.api.frame.VirtualFrame frame) throws com.oracle.truffle.api.nodes.UnexpectedResultException
      Description copied from class: JavaScriptNode
      Like JavaScriptNode.execute(VirtualFrame) except that it tries to convert the result value to an int. A node can override this method if it has a better way to producing a value of type int.
      Overrides:
      executeInt in class JavaScriptNode
      Parameters:
      frame - the frame of the currently executing guest language method
      Returns:
      the value of the execution as an int
      Throws:
      com.oracle.truffle.api.nodes.UnexpectedResultException - if a loss-free conversion of the result to int is not possible

      Overrides:
      executeDouble in class JavaScriptNode
      Parameters:
      frame - the frame of the currently executing guest language method
      Returns:
