Constructor Detail

DiscardResultNode

protected DiscardResultNode(JavaScriptNode operand)

Method Detail

create

public static JavaScriptNode create(JavaScriptNode operand)

isResultAlwaysOfType

public boolean isResultAlwaysOfType(Class<?> clazz)

Overrides:

isResultAlwaysOfType in class JavaScriptNode

copyUninitialized

protected JavaScriptNode copyUninitialized(Set<Class<? extends com.oracle.truffle.api.instrumentation.Tag>> materializedTags)

Overrides:

copyUninitialized in class JavaScriptNode

execute

public Object execute(com.oracle.truffle.api.frame.VirtualFrame frame,
                      Object operandValue)

Specified by:

execute in class JSUnaryNode

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

Parameters:

frame - the frame of the currently executing guest language method

Returns:

the value of the execution

executeVoid

public void executeVoid(com.oracle.truffle.api.frame.VirtualFrame frame)

Description copied from class: JavaScriptNode

Like JavaScriptNode.execute(VirtualFrame) except that it throws away the result. A node can override this method if it has a better way to execute without producing a value.

Overrides:

executeVoid in class JavaScriptNode

Parameters:

frame - the frame of the currently executing guest language method
