Method Detail

randomSeedBigInteger

public static BigInteger randomSeedBigInteger(Random random)

randomSeed

public static RubyBignum randomSeed(Ruby runtime)

createRandomClass

public static RubyClass createRandomClass(Ruby runtime)

initialize

public IRubyObject initialize(ThreadContext context,

initialize_copy

public IRubyObject initialize_copy(IRubyObject orig)

Description copied from class: RubyBasicObject

rb_obj_init_copy Initializes this object as a copy of the original, that is the parameter to this object. Will make sure that the argument actually has the same real class as this object. It shouldn't be possible to initialize an object with something totally different.
