Public Member Functions
virtual void	init_sampler (MedRepository &rep)
	The sampler need repository for Age filters if exist and some samplers also uses bdate.

void	get_sampling_options (const unordered_map< int, vector< pair< int, int > > > &pid_time_ranges, unordered_map< int, vector< int > > &pid_options) const
	The sampling options - calls _get_sampling_options, before that applies filters.

virtual void	_get_sampling_options (const unordered_map< int, vector< pair< int, int > > > &pid_time_ranges, unordered_map< int, vector< int > > &pid_options) const =0
	The specific sampler get_options to implement.

void	set_filters (const string &filtering_str)
	stores filters prior to sampling

Public Member Functions inherited from SerializableObject
virtual int	version () const
	Relevant for serializations.

virtual string	my_class_name () const
	For better handling of serializations it is highly recommended that each SerializableObject inheriting class will implement the next method.

virtual void	serialized_fields_name (vector< string > &field_names) const
	The names of the serialized fields.

virtual void *	new_polymorphic (string derived_name)
	for polymorphic classes that want to be able to serialize/deserialize a pointer * to the derived class given its type one needs to implement this function to return a new to the derived class given its type (as in my_type)

virtual void	pre_serialization ()

virtual void	post_deserialization ()

virtual size_t	get_size ()
	Gets bytes sizes for serializations.

virtual size_t	serialize (unsigned char *blob)
	Serialiazing object to blob memory. return number ob bytes wrote to memory.

virtual size_t	deserialize (unsigned char *blob)
	Deserialiazing blob to object. returns number of bytes read.

size_t	deserialize_vec (vector< unsigned char > &blob)

virtual size_t	serialize (vector< unsigned char > &blob)

virtual size_t	deserialize (vector< unsigned char > &blob)

Member Function Documentation

◆ _get_sampling_options()

virtual void MedSamplingStrategy::_get_sampling_options	(	const unordered_map< int, vector< pair< int, int > > > &	pid_time_ranges,
		unordered_map< int, vector< int > > &	pid_options
	)		const

pure virtual

The specific sampler get_options to implement.

Implemented in MedSamplingTimeWindow, MedSamplingAge, MedSamplingDates, MedSamplingFixedTime, and MedSamplingStick.

◆ init_sampler()

void MedSamplingStrategy::init_sampler ( MedRepository & rep )

virtual

The sampler need repository for Age filters if exist and some samplers also uses bdate.

Reimplemented in MedSamplingStick.
