|---|---|
static RubyClass |
createNilClass(Ruby runtime) |
java.lang.Class<?> |
getJavaClass()
Will return the Java interface that most closely can represent
this object, when working through JAva integration
translations.
|
int |
getNativeTypeIndex()
This is overridden in the other concrete Java builtins to provide a fast way
to determine what type they are.
|
RubyClass |
getSingletonClass()
rb_singleton_class
Note: this method is specialized for RubyFixnum, RubySymbol,
RubyNil and RubyBoolean
Will either return the existing singleton class for this
object, or create a new one and return that.
|
RubyFixnum |
hash(ThreadContext context) |
int |
hashCode()
Override the Object#hashCode method to make sure that the Ruby
hash is actually used as the hashcode for Ruby objects.
|
RubyFixnum |
id()
rb_obj_id
Return the internal id of an object.
|
static RubyString |
inspect(IRubyObject recv)
nil_inspect
|
boolean |
isImmediate()
Is object immediate (def: Fixnum, Symbol, true, false, nil?).
|
IRubyObject |
nil_p() |
static RubyBoolean |
op_and(IRubyObject recv,
IRubyObject obj)
nil_and
|
static RubyBoolean |
op_or(IRubyObject recv,
IRubyObject obj)
nil_or
|
static RubyBoolean |
op_xor(IRubyObject recv,
IRubyObject obj)
nil_xor
|
static IRubyObject |
rationalize(ThreadContext context,
IRubyObject recv,
IRubyObject[] args)
nilclass_rationalize
|
IRubyObject |
taint(ThreadContext context)
rb_obj_taint
call-seq:
obj.taint -> obj
Marks obj as tainted---if the
$SAFE level is
set appropriately, many method calls which might alter the running
programs environment will refuse to accept tainted strings. |
static RubyArray |
to_a(ThreadContext context,
IRubyObject recv)
nil_to_a
|
static IRubyObject |
to_c(ThreadContext context,
IRubyObject recv)
nilclass_to_c
|
static RubyFloat |
to_f(ThreadContext context,
IRubyObject recv)
nil_to_f
|
static RubyHash |
to_h(ThreadContext context,
IRubyObject recv) |
static RubyFixnum |
to_i(ThreadContext context,
IRubyObject recv)
nil_to_i
|
static IRubyObject |
to_r(ThreadContext context,
IRubyObject recv)
nilclass_to_r
|
static RubyString |
to_s(ThreadContext context,
IRubyObject recv)
nil_to_s
|
java.lang.Object |
toJava(java.lang.Class target)
Convert the object to the specified Java class, if possible.
|
static RubyClass |
type(IRubyObject recv)
nil_type
