booted

public static void booted()

isBooted

public static boolean isBooted()

maxDirectMemory

public static long maxDirectMemory()

isDirectMemoryPageAligned

public static boolean isDirectMemoryPageAligned()

allowArraySyntax

public static boolean allowArraySyntax()

allowGetCallerClass

public static boolean allowGetCallerClass()

getSavedProperty

public static java.lang.String getSavedProperty(java.lang.String key)

Returns the system property of the specified key saved at system initialization time. This method should only be used for the system properties that are not changed during runtime. It accesses a private copy of the system properties so that user's locking of the system properties object will not cause the library to deadlock. Note that the saved system properties do not include the ones set by sun.misc.Version.init().

saveAndRemoveProperties

public static void saveAndRemoveProperties(java.util.Properties props)

initializeOSEnvironment

public static void initializeOSEnvironment()

getFinalRefCount

public static int getFinalRefCount()

getPeakFinalRefCount

public static int getPeakFinalRefCount()

addFinalRefCount

public static void addFinalRefCount(int n)

toThreadState

public static java.lang.Thread.State toThreadState(int threadStatus)

Returns Thread.State for the given threadStatus

latestUserDefinedLoader

public static java.lang.ClassLoader latestUserDefinedLoader()
