foreach_pad

Description:

[ Version ( since = "1.14" ) ]
public bool foreach_pad (ElementForeachPadFunc func)

Call func with user_data for each of this's pads.

func will be called exactly once for each pad that exists at the time of this call, unless one of the calls to func returns false in which case we will stop iterating pads and return early. If new pads are added or pads are removed while pads are being iterated, this will not be taken into account until next time this function is used.

Parameters:

this	a Element to iterate pads of
func	function to call for each pad
user_data	user data passed to `func`

Returns:

false if this had no pads or if one of the calls to func returned false.
