Detailed Description

Interface for building a repository of vectors with classifiers to map them to discrete features.

Remarks: This interface has the transaction context logically enclosed in the object, though use in a multithreaded context does not make much sense. Thread safety of the interface is guaranteed, but not the performance in a multithreaded context. It is thought as class that internally makes heavily use of multithreading, but is not thought to be fed by mutliple threads.

Constructor & Destructor Documentation

virtual strus::VectorStorageTransactionInterface::~VectorStorageTransactionInterface ( )

inlinevirtual

Destructor.

virtual void strus::VectorStorageTransactionInterface::clear ( )

pure virtual

Clear all vectors,types and feature names in the storage.

virtual bool strus::VectorStorageTransactionInterface::commit ( )

pure virtual

Ensure the persistent storage of the features added with addFeature(const std::string&,const WordVector&) till now.

virtual void strus::VectorStorageTransactionInterface::defineFeature	(	const std::string &	type,
		const std::string &	feat
	)

pure virtual

Define a feature without vector.

Parameters

[in]	type	of the feature to add
[in]	feat	name of the feature to add

virtual void strus::VectorStorageTransactionInterface::defineScalar	(	const std::string &	name,
		double	value
	)

pure virtual

Define some scalar configuration parameter used in calculation (depending on implementation)

Parameters

[in]	name	name of the variable (depending on implementation)
[in]	value	value assigned to the variable

virtual void strus::VectorStorageTransactionInterface::defineVector	(	const std::string &	type,
		const std::string &	feat,
		const WordVector &	vec
	)

pure virtual

Define a vector for a feature for later retrieval.

Parameters

[in]	type	of the feature associated with the vector
[in]	feat	name of the feature associated with the vector
[in]	vec	vector to define for this feature

virtual void strus::VectorStorageTransactionInterface::rollback ( )

pure virtual

Rollback of the transaction, no changes made.
