Method Detail

condition

public LogicNode condition()

setCondition

public void setCondition(LogicNode x)

getReason

public DeoptimizationReason getReason()

getAction

public DeoptimizationAction getAction()

getSpeculation

public JavaConstant getSpeculation()

isNegated

public boolean isNegated()

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

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

lowerToIf

public DeoptimizeNode lowerToIf()

canDeoptimize

public boolean canDeoptimize()

Description copied from interface: DeoptimizingNode

Determines if this node needs deoptimization information.

Specified by:

canDeoptimize in interface DeoptimizingNode
