Member Function Documentation

template<class T>

virtual void Storage_Manager< T >::getEntityClass	(	key	e,
		sClass &	c,
		struct hazy_model &	m
	)			[pure virtual]

Retrieves the class of the entity.

Parameters:

[in]	e	entitiy id
[out]	c	class of the entity
[in]	m	hazy model that we use to classify the entity

Implemented in Hybrid_Storage_Manager< T >, STLMainMemory_Storage_Manager< T >, Ondisk_Storage_Manager< T >, Ondisk_Storage_Manager< FVector >, and Ondisk_Storage_Manager< SVector >.

template<class T>

virtual void Storage_Manager< T >::getNumInClass	(	sClass	c,
		int &	nClass,
		struct hazy_model &	m,
		double &	waste_time
	)			[pure virtual]

Retrieves # of elements that belong to a given class.

Parameters:

[in]	c	class that we ask # of elements belong it
[out]	nClass	# of elements in the class
[in]	m	hazy model that we use to classify entities
[out]	waste_time	waste time calculated during the method execution

Implemented in Hybrid_Storage_Manager< T >, STLMainMemory_Storage_Manager< T >, Ondisk_Storage_Manager< T >, Ondisk_Storage_Manager< FVector >, and Ondisk_Storage_Manager< SVector >.

template<class T>

virtual void Storage_Manager< T >::incrementalUpdate	(	struct hazy_model &	m,
		double &	waste_time
	)			[pure virtual]

Makes an incremental update on the entities by using hazy model.

Parameters:

[in]	m	hazy model that we use to update entities classes
[out]	waste_time	waste time calcaulted during the method execution

Implemented in Hybrid_Storage_Manager< T >, STLMainMemory_Storage_Manager< T >, Ondisk_Storage_Manager< T >, Ondisk_Storage_Manager< FVector >, and Ondisk_Storage_Manager< SVector >.

template<class T>

virtual void Storage_Manager< T >::insertEntity	(	struct hazy_model &	m,
		key	e,
		T	f
	)			[pure virtual]

Inserts the entity to the storage manager.

Parameters:

[in]	m	hazy model which is used when the approach is hazy, because we need to calculate eps value
[in]	e	id of the entity
[in]	f	feature vector of the entity

Implemented in Hybrid_Storage_Manager< T >, STLMainMemory_Storage_Manager< T >, Ondisk_Storage_Manager< T >, Ondisk_Storage_Manager_Dense, Ondisk_Storage_Manager_Sparse, Ondisk_Storage_Manager< FVector >, and Ondisk_Storage_Manager< SVector >.

template<class T>

int Storage_Manager< T >::loadFromDatabase

(

template<class T>

void Storage_Manager< T >::loadFromFile	(	struct hazy_model &	m,
		const char *	szFileName
	)			[virtual]

Loads entities from the given file.

Parameters:

[in]	m	hazy model
[in]	szFileName	file name

template<class T>

virtual void Storage_Manager< T >::resort

(

struct hazy_model &

m

)

[pure virtual]

Makes a resort to reorganize entities according to their epsilon values.

Parameters:

[in]
