Method Detail

getStatements

public final JavaScriptNode[] getStatements()

Specified by:

getStatements in interface SequenceNode

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

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,
                        JavaScriptNode node,
                        int index,
                        int argument)

Specified by:

executeVoid in interface com.oracle.truffle.api.nodes.BlockNode.ElementExecutor<JavaScriptNode>

executeGeneric

public Object executeGeneric(com.oracle.truffle.api.frame.VirtualFrame frame,
                             JavaScriptNode node,
                             int index,
                             int argument)

Specified by:

executeGeneric in interface com.oracle.truffle.api.nodes.BlockNode.ElementExecutor<JavaScriptNode>

filterStatements

protected static JavaScriptNode filterStatements(JavaScriptNode[] originalStatements,
                                                 boolean exprBlock)

Filter out empty statements, unwrap void nodes, and inline block nodes. If creating an expression block, for the last statement, only inline expression block nodes.

newListFromRange

protected static ArrayList<JavaScriptNode> newListFromRange(JavaScriptNode[] statements,
                                                            int from,
                                                            int to)
