Method Detail

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

appendScopeFrame

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

Specified by:

appendScopeFrame in class BlockScopeNode

exitScope

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

Specified by:

exitScope in class BlockScopeNode

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.

Overrides:

execute in class BlockScopeNode

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 BlockScopeNode

Parameters:

frame - the frame of the currently executing guest language method

getFrameDescriptor

public com.oracle.truffle.api.frame.FrameDescriptor getFrameDescriptor()

Specified by:

getFrameDescriptor in interface FrameDescriptorProvider

resume

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

Specified by:

resume in interface ResumableNode

copyUninitialized

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

Overrides:

copyUninitialized in class JavaScriptNode
