Classes
struct	plssvm::default_init< T >
	This class denotes an explicit default value initialization used to distinguish between the default value or user provided initialization in the default_value class. More...
class	plssvm::default_value< T >
	This class encapsulates a value that may be a default value or not. More...
struct	plssvm::is_default_value< T >
	Test whether the given type T is of type plssvm::default_value ignoring all top-level const, volatile, and reference qualifiers. More...
struct	std::hash< plssvm::default_value< T > >
	Hashing struct specialization in the std namespace for a default_value. More...

Namespaces
	plssvm
	The main namespace containing all public API functions.
