		void *	p6,
		void *	p7,

Calls an object method specified by method name.

This operation is untyped, and the contents of the stack following the method name argument are blindly passed to the method called.

Parameters

x	object pointer
s	method name
p1	untyped arguments passed on to the method
p2	untyped arguments passed on to the method
p3	untyped arguments passed on to the method
p4	untyped arguments passed on to the method

p6	untyped arguments passed on to the method
p7	untyped arguments passed on to the method
p8	untyped arguments passed on to the method

Warning

It is important to know any necessary arguments for untyped constructors such as those used by jit_matrix or jit_attr_offset.

Returns

method dependent, but uses void * as a super type.

void* jit_object_method_typed	(	void *	x,
		t_symbol *	s,
		long	ac,
		t_atom *	av,
		t_atom *	rv
	)

Calls a typed object method specified by method name.

This operation only supports methods which are typed–i.e. it cannot be used to call private, untyped A_CANT methods.

Parameters

x	object pointer
s	method name
ac	argument count
av	argument vector
rv	return value for A_GIMMEBACK methods

Returns

method dependent, but uses void * as a super type.

		void *	p4,
		void *	p5,
		void *	p6,
		void *	p7,

Instantiates an object specified by class name.

This function may used to create instances of any Jitter object.

Parameters

p1	untyped arguments passed on to the constructor
p2	untyped arguments passed on to the constructor
p3	untyped arguments passed on to the constructor
p4	untyped arguments passed on to the constructor
p5	untyped arguments passed on to the constructor
p6	untyped arguments passed on to the constructor
p7	untyped arguments passed on to the constructor
p8	untyped arguments passed on to the constructor
dummy	unused

Warning

It is important to know any necessary arguments for untyped constructors such as those used by jit_matrix or jit_attr_offset.

Returns

If successful, a valid object pointer. Otherwise, NULL.

jit_object_notify()

t_jit_err jit_object_notify	(	void *	x,
		t_symbol *	s,
		void *	data
	)

Notifies all client objects for a named server object.

Parameters

x	server object pointer
s	notification message
data	message specific data

Returns

t_jit_err error code

References object_notify().

Referenced by jit_matrix_setinfo(), and jit_matrix_setinfo_ex().

Here is the call graph for this function:

jit_object_register()

void* jit_object_register	(	void *	x,
		t_symbol *	s
	)

Registers an object in the named object registry.

Parameters

x	object pointer
s	object name

Returns

object pointer

Warning

It is important to use the object pointer returned by jit_object_register, since if there is an existing object with the same name and class, it could free the input object and pass back a reference to the previously defined object.
