public abstract static class JSToInt32Node.JSToInt32UnaryNode extends JSUnaryNode

  • Field Details

    • bitwiseOr

      protected final boolean bitwiseOr
      Whether this node is used to implement x | 0. This optimization is valid insofar as x does not overload operators.

  • Constructor Details

    • JSToInt32UnaryNode

      protected JSToInt32UnaryNode(JavaScriptNode operand, boolean bitwiseOr)

  • Method Details

    • execute

      public final 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
      Parameters:
      frame - the frame of the currently executing guest language method
      Returns:
      the value of the execution

    • executeInt

      public abstract int executeInt(com.oracle.truffle.api.frame.VirtualFrame frame)
      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
