Class JSTypeofIdenticalNode

java.lang.Object
com.oracle.truffle.api.nodes.Node
com.oracle.truffle.js.nodes.JavaScriptBaseNode
com.oracle.truffle.js.nodes.JavaScriptNode
com.oracle.truffle.js.nodes.unary.JSUnaryNode
com.oracle.truffle.js.nodes.binary.JSTypeofIdenticalNode
All Implemented Interfaces:
com.oracle.truffle.api.instrumentation.InstrumentableNode, com.oracle.truffle.api.nodes.NodeInterface, Cloneable
public abstract class JSTypeofIdenticalNode extends JSUnaryNode
This node optimizes the code patterns of typeof(a) === "typename" and "typename" == typeof (a). It thus combines a TypeOfNode and an IdenticalNode or EqualsNode (both show the same behavior in this case).

    • 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

    • executeBoolean

      public abstract boolean executeBoolean(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 a boolean. A node can override this method if it has a better way to producing a value of type boolean.
      Overrides:
      executeBoolean in class JavaScriptNode
      Parameters:
      frame - the frame of the currently executing guest language method
      Returns:
      the value of the execution as a boolean
