Method Details

create

public static TryCatchNode create(JSContext context,
 JavaScriptNode tryBlock,
 JavaScriptNode catchBlock,
 JSWriteFrameSlotNode writeErrorVar,
 BlockScopeNode blockScope,
 JavaScriptNode destructuring,
 JavaScriptNode conditionExpression)

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

copyUninitialized

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

Overrides:

copyUninitialized in class JavaScriptNode

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

executeVoid

public final 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,
 int stateSlot)

Specified by:

resume in interface ResumableNode
