virtualize

public void virtualize(VirtualizerTool tool)

Description copied from interface: Virtualizable

A node class can implement this method to convey information about what its effect would be if some of its inputs were virtualized. All modifications must be made through the supplied tool, and not directly on the node, because by the time this method is called the virtualized/non-virtualized state is still speculative and might not hold because of loops, etc.

Specified by:

virtualize in interface Virtualizable

Parameters:

tool - the tool used to describe the effects of this node

findLength

public ValueNode findLength(ArrayLengthProvider.FindLengthMode mode,
                            jdk.vm.ci.meta.ConstantReflectionProvider constantReflection)

Description copied from interface: ArrayLengthProvider

Returns the length of the array described by this node, or null if it is not available. Details of the different modes are documented in ArrayLengthProvider.FindLengthMode. This method should not be called directly. Use GraphUtil.arrayLength(org.graalvm.compiler.nodes.ValueNode, org.graalvm.compiler.nodes.spi.ArrayLengthProvider.FindLengthMode, jdk.vm.ci.meta.ConstantReflectionProvider) instead.

Specified by:

findLength in interface ArrayLengthProvider
