Class TypeSwitchNode

java.lang.Object

org.graalvm.compiler.graph.Node

org.graalvm.compiler.nodes.ValueNode

org.graalvm.compiler.nodes.FixedNode

org.graalvm.compiler.nodes.ControlSplitNode

org.graalvm.compiler.nodes.extended.SwitchNode

org.graalvm.compiler.nodes.java.TypeSwitchNode

All Implemented Interfaces:

Cloneable, Formattable, SimplifiableMarker, FixedNodeInterface, LIRLowerable, Simplifiable, ValueNodeInterface

public final class TypeSwitchNode
extends SwitchNode
implements LIRLowerable, Simplifiable

The TypeSwitchNode performs a lookup based on the type of the input value. The type comparison is an exact type comparison, not an instanceof.
