Detailed Description

Macro Definition Documentation

◆ RUBY_INTEGER_UNIFICATION

#define RUBY_INTEGER_UNIFICATION 1

Deprecated:: This macro once was a thing in the old days, but makes no sense any longer today.

Exists here for backwards compatibility only. You can safely forget about it.

Definition at line 54 of file globals.h.

Function Documentation

◆ rb_any_to_s()

VALUE rb_any_to_s ( VALUE obj )

Generates a textual representation of the given object.

Parameters

[in] obj Arbitrary ruby object.

Returns: An instance of rb_cString that represents obj.

Note: This is the default implementation of Object#to_s that each subclasses want to override.

Definition at line 669 of file object.c.

◆ rb_Array()

VALUE rb_Array ( VALUE val )

This is the logic behind Kernel#Array.

Arguments are converted by first trying #to_ary, then #to_a, and if both failed, returns an array of length 1 that contains the passed argument as the sole contents.

Parameters

[in] val An object to convert.

Returns: An instance of rb_cArray.

Definition at line 3750 of file object.c.

◆ rb_check_convert_type()

VALUE rb_check_convert_type	(	VALUE	val,
		int	type,
		const char *	name,
		const char *	mid
	)

Identical to rb_convert_type(), except it returns RUBY_Qnil instead of raising exceptions, in case of conversion failure.

It still raises exceptions for various reasons, like when the conversion method itself raises, though.

Parameters

[in]	val	An object to convert.
[in]	type	A value of enum ruby_value_type.
[in]	name	Name to display on error (e.g. "Array").
[in]	mid	Conversion method (e.g. "to_ary").

Exceptions

rb_eTypeError The mid does not generate type.

Return values

RUBY_Qnil	No conversion defined.
otherwise	An object of the specified type.

Definition at line 3115 of file object.c.

◆ rb_check_to_float()

VALUE rb_check_to_float ( VALUE val )

This is complicated.

When the passed object is already an instance of rb_cFloat, just returns it as-is.
When the passed object is something numeric, the function tries to convert it using #to_f method.
- If that conversion fails (this happens for instance when the numeric is a complex) it returns RUBY_Qnil.
- Otherwise returns the conversion result.
Otherwise it also returns RUBY_Qnil.

Parameters

[in] val An object to convert.

Return values

RUBY_Qnil	Conversion from `val` to float is undefined.
otherwise	Converted result.

Definition at line 3634 of file object.c.

◆ rb_check_to_int()

VALUE rb_check_to_int ( VALUE val )

Identical to rb_check_to_integer(), except it uses #to_int for conversion.

Parameters

[in] val An object to convert.

Exceptions

rb_eTypeError #to_int does not return an integer.

Return values

RUBY_Qnil	No conversion defined.
otherwise	An instance of rb_cInteger.

Definition at line 3194 of file object.c.

◆ rb_check_to_integer()

VALUE rb_check_to_integer	(	VALUE	val,
		const char *	mid
	)

Identical to rb_check_convert_type(), except the return value type is fixed to rb_cInteger.

Parameters

[in]	val	An object to convert.
[in]	mid	Conversion method (e.g. "to_ary").

Exceptions

rb_eTypeError The mid does not generate an integer.

Return values

RUBY_Qnil	No conversion defined.
otherwise	An instance of rb_cInteger.

Definition at line 3175 of file object.c.

Referenced by rb_io_extract_modeenc().

◆ rb_class_get_superclass()

VALUE rb_class_get_superclass ( VALUE klass )

Returns the superclass of a class.

Parameters

[in] klass An object of RClass.

Return values

RUBY_Qfalse	`klass` has no super class.
otherwise	Raw superclass of `klass`

See also: rb_class_superclass

Q&A

Q: How can a class have no super class?
A: klass could be a module. Or it could be rb_cBasicObject.
Q: What do you mean by "raw" superclass?
A: This is a really good question. The answer is that this function returns something different from what you would normally expect. On occasions ruby inserts hidden classes in a hierarchy of class inheritance behind-the-scene. Such classes are called "iclass"es and distinguished using RUBY_T_ICLASS in C level. They are truly transparent from Ruby level but can be accessed from C, by using this API.

Definition at line 2171 of file object.c.

◆ rb_class_inherited_p()

VALUE rb_class_inherited_p	(	VALUE	scion,
		VALUE	ascendant
	)

Determines if the given two modules are relatives.

Parameters

[in]	scion	Possible subclass.
[in]	ascendant	Possible superclass.

Exceptions

rb_eTypeError ascendant is not a module.

Return values

RUBY_Qtrue	`scion` inherits, or is equal to `ascendant`.
RUBY_Qfalse	`ascendant` inherits `scion`.
RUBY_Qnil	They are not relatives.

Definition at line 1764 of file object.c.

◆ rb_class_new_instance()

VALUE rb_class_new_instance	(	int	argc,
		const VALUE *	argv,
		VALUE	klass
	)

Allocates, then initialises an instance of the given class.

It first calls the passed class' allocator to obtain an uninitialised object, then calls its initialiser with the remaining arguments.

Parameters

[in]	argc	Number of objects of `argv`.
[in]	argv	Arguments passed to `#initialize`.
[in]	klass	An instance of rb_cClass.

Exceptions

rb_eTypeError	`klass`'s allocator is undefined.
rb_eException	Any exceptions can happen inside.

Returns: An allocated new instance of klass.

Definition at line 2134 of file object.c.

◆ rb_class_new_instance_kw()

VALUE rb_class_new_instance_kw	(	int	argc,
		const VALUE *	argv,
		VALUE	klass,
		int	kw_splat
	)

Identical to rb_class_new_instance(), except you can specify how to handle the last element of the given array.

Parameters

[in]	argc	Number of objects of `argv`.
[in]	argv	Arbitrary number of method arguments.
[in]	klass	An instance of rb_cClass.
[in]	kw_splat	Handling of keyword parameters: RB_NO_KEYWORDS `argv`'s last is not a keyword argument. RB_PASS_KEYWORDS `argv`'s last is a keyword argument. RB_PASS_CALLED_KEYWORDS it depends if there is a passed block.

Exceptions

rb_eTypeError	`klass`'s allocator is undefined.
rb_eException	Any exceptions can happen inside.

Returns: An allocated new instance of klass.

Definition at line 2122 of file object.c.

◆ rb_class_new_instance_pass_kw()

VALUE rb_class_new_instance_pass_kw	(	int	argc,
		const VALUE *	argv,
		VALUE	klass
	)

Identical to rb_class_new_instance(), except it passes the passed keywords if any to the #initialize method.

Parameters

[in]	argc	Number of objects of `argv`.
[in]	argv	Arbitrary number of method arguments.
[in]	klass	An instance of rb_cClass.

Exceptions

rb_eTypeError	`klass`'s allocator is undefined.
rb_eException	Any exceptions can happen inside.

Returns: An allocated new instance of klass.

Note: This is the implementation of Object.new.

Definition at line 2111 of file object.c.

◆ rb_class_of()

static VALUE rb_class_of ( VALUE obj )

inlinestatic

Object to class mapping function.

Every object have its class. This function obtains that.

Parameters

Returns: The class of the given object.

Definition at line 172 of file globals.h.

◆ rb_class_real()

VALUE rb_class_real ( VALUE klass )

As the name implies there are class objects that are surreal. This function takes a class, traverses its ancestry tree, and returns its nearest ancestor which is neither a module nor a singleton class.

Parameters

[in] klass An instance of rb_cClass.

Return values

RUBY_Qfalse	No real class in `klass`' ancestry tree.
klass	`klass` itself is a real class.
otherwise	Nearest ancestor of `klass` who is real.

Definition at line 237 of file object.c.

Converts a textual representation of a real number into a numeric, which is the nearest value that the return type can represent, of the value that the argument represents.

This is in fact a 2-in-1 function whose behaviour can be controlled using the second (mode) argument. If the mode is zero, this function is in "historical" mode which only understands "floating-constant" defined at ISO/IEC 9899:1990 section 6.1.3.1. If the mode is nonzero, it is in "extended" mode, which also accepts "hexadecimal-floating-constant" defined at ISO/IEC 9899:2018 section 6.4.4.2.

Parameters

[in]	str	A textual representation of a real number.
[in]	mode	Conversion mode, as described above.

Exceptions

rb_eArgError Malformed str passed.

See also: https://bugs.ruby-lang.org/issues/2969

Note: Null pointers are allowed, and it returns 0.0 then.

◆ rb_eql()

int rb_eql	(	VALUE	lhs,
		VALUE	rhs
	)

Checks for equality of the passed objects, in terms of Object#eql?.

Parameters

[in]	lhs	Comparison left hand side.
[in]	rhs	Comparison right hand side.

Return values

non-zero	They are equal.
0	Otherwise.

Note: This function actually calls lhs.eql?(rhs) so you cannot implement your class' #eql? method using it.

Definition at line 192 of file object.c.

◆ rb_equal()

VALUE rb_equal	(	VALUE	lhs,
		VALUE	rhs
	)

This function is an optimised version of calling #==.

It checks equality between two objects by first doing a fast identity check using using C's == (same as BasicObject#equal?). If that check fails, it calls #== dynamically. This optimisation actually affects semantics, because when #== returns false for the same object obj, rb_equal(obj, obj) would still return true. This happens for Float::NAN, where Float::NAN == Float::NAN is false, but rb_equal(Float::NAN, Float::NAN) is true.

Parameters

[in]	lhs	Comparison LHS.
[in]	rhs	Comparison RHS.

Return values

RUBY_Qtrue	They are the same.
RUBY_Qfalse	They are different.

◆ rb_Float()

VALUE rb_Float ( VALUE val )

This is the logic behind Kernel#Float.

Numeric types are converted directly to the nearest value that a Float can represent. Strings are interpreted strictly; only leading/trailing whitespaces are allowed except what strtod understands. Anything else are converted using #to_f.

This is slightly stricter than String#to_f.

Parameters

[in] val An object to convert.

Exceptions

rb_eArgError	Malformed `val` passed.
rb_eTypeError	No conversion defined.

Returns: An instance of rb_cFloat.

Definition at line 3595 of file object.c.

Referenced by rb_str_format().

◆ rb_Hash()

VALUE rb_Hash ( VALUE val )

Equivalent to Kernel#Hash in Ruby.

This is the logic behind Kernel#Hash.

Definition at line 3793 of file object.c.

◆ rb_inspect()

VALUE rb_inspect ( VALUE obj )

Generates a human-readable textual representation of the given object.

This is largely similar to Ruby level Object#inspect but not the same; it additionally escapes the inspection result so that the string be compatible with that of default internal (or default external, if absent).

Parameters

[in] obj Arbitrary ruby object.

Returns: An instance of rb_cString that represents obj.

Definition at line 680 of file object.c.

Referenced by rb_cmperr(), rb_p(), and rb_str_format().

◆ rb_Integer()

VALUE rb_Integer ( VALUE val )

This is the logic behind Kernel#Integer.

Numeric types are converted directly, with floating point numbers being truncated. Strings are interpreted strictly; only leading/trailing whitespaces, plus/minus sign, radix indicators such as 0x, digits, and underscores are allowed. Anything else are converted by first trying #to_int, then #to_i.

This is slightly stricter than String#to_i.

Parameters

[in] val An object to convert.

Exceptions

rb_eArgError	Malformed `val` passed.
rb_eTypeError	No conversion defined.

Returns: An instance of rb_cInteger.

Definition at line 3263 of file object.c.

Referenced by rb_str_format().

◆ rb_num2dbl()

double rb_num2dbl ( VALUE num )

Converts an instance of rb_cNumeric into C's double.

Parameters

[in] num Something numeric.

Exceptions

rb_eTypeError num is not a numeric.

Returns: The passed value converted into C's double.

Definition at line 3686 of file object.c.

◆ rb_obj_alloc()

VALUE rb_obj_alloc ( VALUE klass )

Allocates an instance of the given class.

Parameters

[in] klass A class to instantiate.

Exceptions

rb_eTypeError klass is not a class.

Returns: An allocated, not yet initialised instance of klass.

Note: It calls the allocator defined by rb_define_alloc_func(). You cannot use this function to define an allocator. Use TypedData_Make_Struct or others, instead.; Usually prefer rb_class_new_instance() to rb_obj_alloc() and rb_obj_call_init().

◆ rb_obj_class()

VALUE rb_obj_class ( VALUE obj )

Queries the class of an object.

This is not always identical to RBASIC_CLASS(obj). It searches for the nearest ancestor skipping singleton classes or included modules.

Parameters

[in] obj Object in question.

Returns: The object's class, in a normal sense.

◆ rb_obj_clone()

VALUE rb_obj_clone ( VALUE obj )

Produces a shallow copy of the given object.

Its list of instance variables are copied, but not the objects they reference. It also copies the frozen value state.

Parameters

[in] obj Arbitrary ruby object.

Exceptions

rb_eException #initialize_copy can raise anything.

Returns: A "clone" of obj.

Definition at line 521 of file object.c.

Referenced by rb_eval_string_wrap().

◆ rb_obj_dup()

VALUE rb_obj_dup ( VALUE obj )

Duplicates the given object.

This does almost the same thing as rb_obj_clone() do. However it does not copy the singleton class (if any). It also doesn't copy frozen-ness.

Parameters

[in] obj Arbitrary ruby object.

Exceptions

rb_eException #initialize_copy can raise anything.

Returns: A shallow copy of obj.

◆ rb_obj_hide()

VALUE rb_obj_hide ( VALUE obj )

Make the object invisible from Ruby code.

It is useful to let Ruby's GC manage your internal data structure – The object keeps being managed by GC, but ObjectSpace.each_object never yields the object.
