Method Details

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

executeInt

public int executeInt(com.oracle.truffle.api.frame.VirtualFrame frame)
               throws com.oracle.truffle.api.nodes.UnexpectedResultException

Description copied from class: JavaScriptNode

Like JavaScriptNode.execute(VirtualFrame) except that it tries to convert the result value to an int. A node can override this method if it has a better way to producing a value of type int.

Overrides:

executeInt in class JavaScriptNode

Parameters:

frame - the frame of the currently executing guest language method

Returns:

the value of the execution as an int

Throws:

com.oracle.truffle.api.nodes.UnexpectedResultException - if a loss-free conversion of the result to int is not possible

executeDouble

public double executeDouble(com.oracle.truffle.api.frame.VirtualFrame frame)
                     throws com.oracle.truffle.api.nodes.UnexpectedResultException

Description copied from class: JavaScriptNode

Like JavaScriptNode.execute(VirtualFrame) except that it tries to convert the result value to a double. A node can override this method if it has a better way to producing a value of type double.

Overrides:

executeDouble in class JavaScriptNode

Parameters:

frame - the frame of the currently executing guest language method

Returns:

the value of the execution as a double

Throws:

com.oracle.truffle.api.nodes.UnexpectedResultException - if a loss-free conversion of the result to double is not possible

executeBoolean

public boolean executeBoolean(com.oracle.truffle.api.frame.VirtualFrame frame)
                       throws com.oracle.truffle.api.nodes.UnexpectedResultException

Description copied from class: JavaScriptNode

Like JavaScriptNode.execute(VirtualFrame) except that it tries to convert the result value to a boolean. A node can override this method if it has a better way to producing a value of type boolean.

Overrides:

executeBoolean in class JavaScriptNode

Parameters:

frame - the frame of the currently executing guest language method

Returns:

the value of the execution as a boolean

Throws:

com.oracle.truffle.api.nodes.UnexpectedResultException - if a loss-free conversion of the result to double is not possible

getLevelFrameNode

public ScopeFrameNode getLevelFrameNode()

Specified by:

getLevelFrameNode in class FrameSlotNode

hasTemporalDeadZone

public boolean hasTemporalDeadZone()

Overrides:

hasTemporalDeadZone in class FrameSlotNode

create

public static TemporalDeadZoneCheckNode create(int slotIndex,
 Object identifier,
 ScopeFrameNode levelFrameNode,
 JavaScriptNode rhs)

copyUninitialized

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

Overrides:

copyUninitialized in class JavaScriptNode
