An object representing the post type, when arg is a single post type name
WOOF_Collection of WOOF_PostType
A collection of zero or more post types, if arg is an arguments array.
An object for silent failure if the post type cannot be found
A synonym for the post_types method, to return a single WOOF_PostType object representing a post type name in the $arg parameter, or multiple post types if the $arg parameter is an arguments array, as would be passed to the WordPress function get_post_types().
Note: For readability, the intention is that this method is usually used to retrieve a single type.
Either a string representing the post type name, OR an array representing args to pass to WordPress’ get_post_types. Note that you CANNOT use the string representation of the arguments for this function, as it will be assumed tat a string is a post type name.
