"""Core of the parser classes
|
||
|
|
|
||
|
|
Collects all methods prefixed with "value_" and builds a dict of
|
||
|
|
their return values. Parser classes will inherit from this class.
|
||
|
|
All methods that begin with "value_" in a parser class will be given
|
||
|
|
the same `data` argument and are expected to pull their corresponding
|
||
|
|
value from the collection.
|
||
|
|
|
||
|
|
These methods return a tuple - their raw value and formatted value.
|
||
|
|
The raw value is a string or tuple of string and the formatted value
|
||
|
|
be of type string, int, float, or tuple.
|
||
|
|
|
||
|
|
If no data is found in a method, the raw value is expected to be None,
|
||
|
|
and for the formatted value, strings will be "null", ints will be 0,
|
||
|
|
floats will be 0.0.
|
||
|
|
|
||
|
|
Args:
|
||
|
|
data (dict): Raw video data
|
||
|
|
rawMode (bool): Returns raw values instead of formatted values
|
||
|
|
includeMissing (bool): If value is missing, return "empty" value
|
||
|
|
|
||
|
|
Returns:
|
||
|
|
dict<str, dict<str, var>>: Parsed data from class methods, may not have every value.
