Field Detail

bitwiseOr

protected final boolean bitwiseOr

Whether this node is used to implement x | 0. This optimization is valid insofar as x does not overload operators.

Constructor Detail

JSToInt32UnaryNode

protected JSToInt32UnaryNode(JavaScriptNode operand,
                             boolean bitwiseOr)

Method Detail

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

executeInt

public abstract int executeInt(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 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

doInteger

protected int doInteger(int value)

doSafeInteger

protected int doSafeInteger(SafeInteger value)

doBoolean

protected int doBoolean(boolean value)

doLong

protected int doLong(long value)

doDoubleFitsInt

protected int doDoubleFitsInt(double value)

doDoubleRepresentableAsSafeInteger

protected int doDoubleRepresentableAsSafeInteger(double value)

doDoubleRepresentableAsLong

protected int doDoubleRepresentableAsLong(double value)

doDouble

protected int doDouble(double value)

doUndefined

protected int doUndefined(Object value)

doNull

protected int doNull(Object value)

doString

protected int doString(com.oracle.truffle.api.strings.TruffleString value,
                       JSStringToNumberNode stringToNumberNode)

doSymbol

protected final int doSymbol(Symbol value)

doBigInt

protected int doBigInt(BigInt value)

doOverloadedOperator

getOverloadedOperatorName

protected com.oracle.truffle.api.strings.TruffleString getOverloadedOperatorName()

doJSObject

protected int doJSObject(JSObject value,
                         JSToDoubleNode toDoubleNode)
