Documentation conventions
|
|
=========================
|
|
|
|
Due to the potential for exponential growth, several abbreviating conventions will be used throughout this
|
|
documentation. These conventions have grown primarily from extremely in-depth discussions of the architecure in IRC.
|
|
This has verified the safety of these conventions, if used properly. There are no known namespace conflicts as long as
|
|
context is rigorously observed.
|
|
|
|
Object classes
|
|
--------------
|
|
|
|
Since everything starts with Gst, we will generally refer to objects by the shorter name, i.e. Element or Pad. These
|
|
names will always have their first letter capitalized.
|
|
|
|
Function names
|
|
--------------
|
|
|
|
Within the context of a given object, functions defined in that object's header and/or source file will have their
|
|
object-specific prefix stripped. For instance, gst_element_add_pad() would be referred to as simply _get_pad(). Note
|
|
that the trailing parentheses should always be present, but sometimes may not be. A prefixing underscore (_) will
|
|
always tell you it's a function, however, regardless of the presence or absence of the trailing parentheses.
|
|
|
|
#defines and enums
|
|
------------------
|
|
|
|
Values and macros defined as enums and preprocessor macros will be referred to in all capitals, as per their
|
|
definition. This includes object flags and element states, as well as general enums. Examples are the states NULL,
|
|
READY, PLAYING, and PAUSED; the element flags DECOUPLED and USE_COTHREAD, and state return values SUCCESS, FAILURE, and
|
|
ASYNC. Where there is a prefix, as in the element flags, this is usually dropped, and implied. Not however that
|
|
element flags should be cross-checked with the header, as there are currently two conventions in use: with and without
|
|
_FLAGS_ in the middle.
