Class TypeSwitchNode

java.lang.Object

com.oracle.graal.graph.Node

com.oracle.graal.nodes.ValueNode

com.oracle.graal.nodes.FixedNode

com.oracle.graal.nodes.ControlSplitNode

com.oracle.graal.nodes.extended.SwitchNode

com.oracle.graal.nodes.java.TypeSwitchNode

All Implemented Interfaces:

IterableNodeType, Simplifiable, LIRLowerable, Cloneable, Formattable, KindProvider

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.

Method Detail

assertKeys

private boolean assertKeys()

Don't allow duplicate keys.

isSorted

public boolean isSorted()

Specified by:

isSorted in class SwitchNode

keyCount

public int keyCount()

Description copied from class: SwitchNode

The number of distinct keys in this switch.

Specified by:

keyCount in class SwitchNode

keyAt

public JavaConstant keyAt(int index)

Description copied from class: SwitchNode

The key at the specified position, encoded in a Constant.

Specified by:

keyAt in class SwitchNode

equalKeys

public boolean equalKeys(SwitchNode switchNode)

Description copied from class: SwitchNode

Returns true if the switch has the same keys in the same order as this switch.

Specified by:

equalKeys in class SwitchNode

typeAt

public ResolvedJavaType typeAt(int index)

generate

public void generate(NodeLIRBuilderTool gen)

Specified by:

generate in interface LIRLowerable

simplify

public void simplify(SimplifierTool tool)

Description copied from class: Node

Must be overridden by subclasses that implement Simplifiable. The implementation in Node exists to obviate the need to cast a node before invoking Simplifiable.simplify(SimplifierTool).

Specified by:

simplify in interface Simplifiable

Overrides:

simplify in class Node
