Class XOptions

java.lang.Object

com.oracle.svm.core.option.XOptions

public class XOptions
extends Object

A parser for the HotSpot-like memory sizing options "-Xmn", "-Xms", "-Xmx", "-Xss". Every option has a corresponding RuntimeOptionKey in SubstrateOptions. So, the resulting behavior is pretty much as if an APIOption was specified for a RuntimeOptionKey.
