Constructor Detail

GlobalConstantNode

protected GlobalConstantNode(com.oracle.truffle.api.strings.TruffleString propertyName,
                             JSConstantNode constantNode)

Method Detail

createGlobalConstant

public static JSTargetableNode createGlobalConstant(com.oracle.truffle.api.strings.TruffleString propertyName,
                                                    Object value)

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

executeWithTarget

public Object executeWithTarget(com.oracle.truffle.api.frame.VirtualFrame frame,
                                Object target)

Specified by:

executeWithTarget in class JSTargetableNode

evaluateTarget

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

Overrides:

evaluateTarget in class JSTargetableNode

getTarget

public JavaScriptNode getTarget()

Overrides:

getTarget in class JSTargetableNode

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

getValue

public Object getValue()

toString

public String toString()

Overrides:

toString in class JavaScriptNode

copyUninitialized

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

Overrides:

copyUninitialized in class JavaScriptNode
