static String

base64(long l, StringBuilder sb)

static StringBuilder

base64$default$2()

static final String

base64chars()

static int

compareIdentityHash(Object a, Object b)

static String

currentTimeMillisToUTCString(long timestamp)

Converts a "currentTimeMillis"-obtained timestamp accordingly:

static <T> Comparator<T>

identityHashComparator(Comparator<T> comp)

Create a comparator which will efficiently use System.identityHashCode, unless that happens to be the same for two non-equals objects, in which case the supplied “real” comparator is used; the comparator must be consistent with equals, otherwise it would not be an enhancement over the identityHashCode.

static boolean

isWindows()

static Pattern

makePattern(String s)

static final <A> Helpers.Requiring<A>

Requiring(A value)

static String

timestamp(long time)
