public static Symbol	create(Address addr)
public boolean	equals(byte[] modUTF8Chars)
public boolean	equals(String string)
public long	fastCompare(Symbol other) Note this comparison is used for vtable sorting only; it doesn't matter what order it defines, as long as it is a total, time-invariant order Since Symbol* are in C_HEAP, their relative order in memory never changes, so use address comparison for speed.
