All Implemented Interfaces:

Node.ValueNumberable, NodeInterface, Canonicalizable, Canonicalizable.Binary<ValueNode>, Lowerable, Cloneable, Formattable, KindProvider

public class InstanceOfDynamicNode
extends LogicNode
implements Canonicalizable.Binary<ValueNode>, Lowerable

The InstanceOfDynamicNode represents a type check where the type being checked is not known at compile time. This is used, for instance, to intrinsify Class.isInstance(Object) .

Method Summary

Modifier and Type	Method and Description
LogicNode	canonical(CanonicalizerTool tool, ValueNode forObject, ValueNode forMirror) Similar to Canonicalizable.canonical(CanonicalizerTool), except that implementations should act as if the current input of the node was the given one, i.e., they should never look at the inputs via the this pointer.
static LogicNode	create(ConstantReflectionProvider constantReflection, ValueNode mirror, ValueNode object)
private static LogicNode	findSynonym(ConstantReflectionProvider constantReflection, ValueNode forObject, ValueNode forMirror)
ValueNode	getX() Gets the current value of the input, so that calling Canonicalizable.Binary.canonical(CanonicalizerTool, Node, Node) with the value returned from this method should behave exactly like Canonicalizable.canonical(CanonicalizerTool).
ValueNode	getY() Gets the current value of the input, so that calling Canonicalizable.Binary.canonical(CanonicalizerTool, Node, Node) with the value returned from this method should behave exactly like Canonicalizable.canonical(CanonicalizerTool).
void	lower(LoweringTool tool) Expand this node into lower level nodes expressing the same semantics.

InstanceOfDynamicNode

public InstanceOfDynamicNode(ValueNode mirror,
                             ValueNode object)

Method Detail

create

public static LogicNode create(ConstantReflectionProvider constantReflection,
                               ValueNode mirror,
                               ValueNode object)

lower

public void lower(LoweringTool tool)

Description copied from interface: Lowerable

Expand this node into lower level nodes expressing the same semantics. If the introduced nodes are themselves lowerable, they should be recursively lowered as part of this call.

Specified by:

lower in interface Lowerable

findSynonym

private static LogicNode findSynonym(ConstantReflectionProvider constantReflection,
                                     ValueNode forObject,
                                     ValueNode forMirror)

canonical

public LogicNode canonical(CanonicalizerTool tool,
                           ValueNode forObject,
                           ValueNode forMirror)

Description copied from interface: Canonicalizable.Binary

Similar to Canonicalizable.canonical(CanonicalizerTool), except that implementations should act as if the current input of the node was the given one, i.e., they should never look at the inputs via the this pointer.

Specified by:

canonical in interface Canonicalizable.Binary<ValueNode>

object

public ValueNode object()

mirror

public ValueNode mirror()

getX

public ValueNode getX()

Description copied from interface: Canonicalizable.Binary

Gets the current value of the input, so that calling Canonicalizable.Binary.canonical(CanonicalizerTool, Node, Node) with the value returned from this method should behave exactly like Canonicalizable.canonical(CanonicalizerTool).

Specified by:

getX in interface Canonicalizable.Binary<ValueNode>

getY

public ValueNode getY()

Description copied from interface: Canonicalizable.Binary

Gets the current value of the input, so that calling Canonicalizable.Binary.canonical(CanonicalizerTool, Node, Node) with the value returned from this method should behave exactly like Canonicalizable.canonical(CanonicalizerTool).

Specified by:

getY in interface Canonicalizable.Binary<ValueNode>
