Method Detail

create

public static BlockScopeNode create(com.oracle.truffle.api.frame.FrameDescriptor frameDescriptor,
                                    com.oracle.truffle.api.frame.FrameSlot parentSlot,
                                    JavaScriptNode block)

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

appendScopeFrame

public abstract com.oracle.truffle.api.frame.VirtualFrame appendScopeFrame(com.oracle.truffle.api.frame.VirtualFrame frame)

exitScope

public abstract void exitScope(com.oracle.truffle.api.frame.VirtualFrame frame)

executeRepeating

public boolean executeRepeating(com.oracle.truffle.api.frame.VirtualFrame frame)

Specified by:

executeRepeating in interface com.oracle.truffle.api.nodes.RepeatingNode

getBlock

public JavaScriptNode getBlock()

isResultAlwaysOfType

public boolean isResultAlwaysOfType(Class<?> clazz)

Overrides:

isResultAlwaysOfType in class JavaScriptNode
