public final class LoadArrayComponentHubNode
extends FixedWithNextNode
implements Lowerable, Canonicalizable.Unary<ValueNode>

Loads the component hub for of the provided array hub. This is a fixed node because on certain VMs, for example the HotSpot VM, the read is only valid when the provided hub is actually an array hub (and not, e.g., a primitive hub), so this node must not float above a possible type check. Properly guarding this node would be possible too, but it is unlikely that the guard would be more flexible than just fixing the node in the control flow.

Method Summary

Modifier and Type	Method and Description
Node	canonical(CanonicalizerTool tool, ValueNode forValue) 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 ValueNode	create(ValueNode value, StampProvider stampProvider, MetaAccessProvider metaAccess, ConstantReflectionProvider constantReflection)
ValueNode	getValue() Gets the current value of the input, so that calling Canonicalizable.Unary.canonical(CanonicalizerTool, Node) with the value returned from this method should behave exactly like Canonicalizable.canonical(CanonicalizerTool).

Method Detail

create

public static ValueNode create(ValueNode value,
                               StampProvider stampProvider,
                               MetaAccessProvider metaAccess,
                               ConstantReflectionProvider constantReflection)

getValue

public ValueNode getValue()

Description copied from interface: Canonicalizable.Unary

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

Specified by:

getValue in interface Canonicalizable.Unary<ValueNode>

canonical

public Node canonical(CanonicalizerTool tool,
                      ValueNode forValue)

Description copied from interface: Canonicalizable.Unary

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.Unary<ValueNode>
