Method Details

create

public static JavaScriptNode create(JavaScriptNode child)

execute

public final 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

executeBoolean

public abstract boolean executeBoolean(com.oracle.truffle.api.frame.VirtualFrame frame)

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

doBoolean

protected static boolean doBoolean(boolean value)

doNull

protected static boolean doNull(Object value)

doUndefined

protected static boolean doUndefined(Object value)

doInt

protected static boolean doInt(int value)

doLong

protected static boolean doLong(long value)

doDouble

protected static boolean doDouble(double value)

doBigInt

protected static boolean doBigInt(BigInt value)

doString

protected static boolean doString(com.oracle.truffle.api.strings.TruffleString value)

doObject

protected static boolean doObject(Object value)

doSymbol

protected static boolean doSymbol(Symbol value)

doForeignObject

protected static boolean doForeignObject(Object value,
 com.oracle.truffle.api.nodes.Node node,
 JSToBooleanNode toBooleanNode)

copyUninitialized

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

Overrides:

copyUninitialized in class JavaScriptNode

isResultAlwaysOfType

public boolean isResultAlwaysOfType(Class<?> clazz)

Overrides:

isResultAlwaysOfType in class JavaScriptNode

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

materializeInstrumentableNodes

public com.oracle.truffle.api.instrumentation.InstrumentableNode materializeInstrumentableNodes(Set<Class<? extends com.oracle.truffle.api.instrumentation.Tag>> materializedTags)
