Enumeration Type Documentation

enum Ender_Item_Function_Flag

Different flags a function can have

See also:

ender_item_function_flags_get

Enumerator:

ENDER_ITEM_FUNCTION_FLAG_IS_METHOD	In case the function belongs to a particular item. In such case the parent of the function is the instance and the first attribute is the instance itself
ENDER_ITEM_FUNCTION_FLAG_THROWS	In case the function throws an exception
ENDER_ITEM_FUNCTION_FLAG_CTOR	In case the function is a constructor
ENDER_ITEM_FUNCTION_FLAG_REF	In case the function increments the reference counting of the parent item
ENDER_ITEM_FUNCTION_FLAG_UNREF	In case the function decrements the reference counting of the parent item
ENDER_ITEM_FUNCTION_FLAG_CALLBACK	In case the function is a callback definition
ENDER_ITEM_FUNCTION_FLAG_VALUE_OF	In case the function describes how an item can be converted into another type. It is useful for example to coneert an object into a string
ENDER_ITEM_FUNCTION_FLAG_DOWNCAST	In case the function implements a way to downcast an object The function can have the following prototypes: void foo_bar_get(void *o, const char **lib, const char **name); void foo_bar_get(void *o, char **lib, char **name); Ender_Item * foo_bar_get(void *o);

EAPI Eina_List* ender_item_function_args_get

(

Ender_Item *

i

)

Get the list of arguments from a function

Parameters:

i	The function to get the arguments from

Returns:

The list of arguments. Use ender_item_unref to free every item on the list

EAPI Ender_Item* ender_item_function_args_at	(	Ender_Item *	i,
		int	idx
	)

Get the argument in a specified index

Parameters:

i	The function to get the argument from
idx	The index on the argument list

Returns:

The argument at the specified index

EAPI int ender_item_function_args_count

(

Ender_Item *

i

)

Count the number of arguments a function has

Parameters:

i	The function to count the number of arguments on

Returns:

The number of arguments

EAPI Ender_Item* ender_item_function_ret_get

(

Ender_Item *

i

)

Get the return item of a function

Parameters:

i	The function to get the return from

Returns:

The return item

Eina_Bool ender_item_function_call	(	Ender_Item *	i,
		Ender_Value *	args,
		Ender_Value *	retval
	)

Call a function

Parameters:

i	The function to call
args	The array of values that matches the number of arguments
retval	The returning value of the function call

Returns:

EINA_TRUE if the call is succesful, EINA_FALSE otherwise

EAPI int ender_item_function_flags_get

(

Ender_Item *

i

)

Get the function flags

Parameters:

i	The function to get the flags from

Returns:

The function flags

EAPI int ender_item_function_throw_position_get

(

Ender_Item *

i

)

Get the index position of the argument that is used for exceptions

A function that has the flag ENDER_ITEM_FUNCTION_FLAG_THROWS has an Eina_Error based argument. This function returns the position of such argument.

Parameters:

i	The function to get the position index from

Returns:

The position index of the argument
