public final class BytecodeExceptionNode
extends AbstractMemoryCheckpoint
implements Lowerable, MemoryCheckpoint.Single

A node that represents an exception thrown implicitly by a Java bytecode. It can be lowered to either a foreign call or a pre-allocated exception object.

Method Detail

getExceptionClass

public Class<? extends Throwable> getExceptionClass()

toString

public String toString(Verbosity verbosity)

Description copied from class: Node

Creates a String representation for this node with a given Verbosity.

Overrides:

toString in class Node

getLocationIdentity

public LocationIdentity getLocationIdentity()

Description copied from interface: MemoryCheckpoint.Single

This method is used to determine which memory location is killed by this node. Returning the special value LocationIdentity.any() will kill all memory locations.

Specified by:

getLocationIdentity in interface MemoryCheckpoint.Single

Returns:

the identity of the location killed by this node.

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

getArguments

public NodeInputList<ValueNode> getArguments()
