Method Detail

create

public static IfNode create(JavaScriptNode condition,
                            JavaScriptNode thenPart,
                            JavaScriptNode elsePart)

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

materializeInstrumentableNodes

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

Specified by:

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

getThenPart

public JavaScriptNode getThenPart()

getElsePart

public JavaScriptNode getElsePart()

getCondition

public JavaScriptNode getCondition()

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

resume

public Object resume(com.oracle.truffle.api.frame.VirtualFrame frame)

Specified by:

resume in interface ResumableNode

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

executeCondition

protected boolean executeCondition(com.oracle.truffle.api.frame.VirtualFrame frame)
