elementType

public ResolvedJavaType elementType()

Gets the element type of the array.

Returns:

the element type of the array

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

createVirtualArrayNode

protected VirtualArrayNode createVirtualArrayNode(int constantLength)

defaultElementValue

protected ConstantNode defaultElementValue()
