Method Detail

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

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

getNodeObject

public Object getNodeObject()

Specified by:

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

Overrides:

getNodeObject in class JSUnaryNode

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

executeInt

public abstract int executeInt(Object operand)

create

public static JavaScriptNode create(JavaScriptNode child)

create

public static JSToInt32Node create()
