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).

TypeOfNode, JSRuntime.typeof(Object)

Method Detail

create

public static JSTypeofIdenticalNode create(JavaScriptNode childNode,

hasTag

public boolean hasTag(Class<? extends com.oracle.truffle.api.instrumentation.Tag> tag)

Specified by:

hasTag in interface com.oracle.truffle.api.instrumentation.InstrumentableNode

Overrides:

hasTag in class JavaScriptNode

materializeInstrumentableNodes

public com.oracle.truffle.api.instrumentation.InstrumentableNode materializeInstrumentableNodes(Set<Class<? extends com.oracle.truffle.api.instrumentation.Tag>> materializedTags)

isResultAlwaysOfType

public boolean isResultAlwaysOfType(Class<?> clazz)

Overrides:

isResultAlwaysOfType in class JavaScriptNode

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
