Detailed Description

Object representing a client connection to a vector storage.

Remarks

The only way to construct a vector storage client instance is to call Context::createVectorStorageClient(const std::string&)

Constructor & Destructor Documentation

strus::VectorStorageClient::VectorStorageClient

(

const VectorStorageClient &

o

)

Copy constructor.

strus::VectorStorageClient::~VectorStorageClient ( )

inline

Destructor.

Member Function Documentation

void strus::VectorStorageClient::close

(

)

Controlled close to free resources (forcing free resources in interpreter context with garbage collector)

StringVector strus::VectorStorageClient::conceptClassNames

(

)

const

Get the list of concept class names defined.

Returns

the list

IndexVector strus::VectorStorageClient::conceptFeatures	(	const String &	conceptClass,
		const Index &	conceptid
	)		const

Get the list of indices of features represented by a learnt concept feature.

Parameters

[in]	conceptClass	name identifying a class of concepts learnt
[in]	conceptid	index (indices of learnt concepts starting from 1)

Returns

the resulting vector indices (index is order of insertion starting from 0)

String strus::VectorStorageClient::config

(

)

const

Get the configuration of this model.

Returns

the configuration string

VectorStorageSearcher strus::VectorStorageClient::createSearcher	(	const Index &	range_from,
		const Index &	range_to
	)		const

Create a searcher object for scanning the vectors for similarity.

Parameters

[in]	range_from	start range of the features for the searcher (possibility to split into multiple searcher instances)
[in]	range_to	end of range of the features for the searcher (possibility to split into multiple searcher instances)

Returns

the vector search interface (with ownership)

VectorStorageTransaction strus::VectorStorageClient::createTransaction

(

)

Create a vector storage transaction instance.

IndexVector strus::VectorStorageClient::featureConcepts	(	const String &	conceptClass,
		const Index &	index
	)		const

Get the set of learnt concepts of a class for a feature defined.

Parameters

[in]	conceptClass	name identifying a class of concepts learnt
[in]	index	index of vector in the order of insertion starting from 0

Returns

the resulting concept feature indices (indices of learnt concepts starting from 1)

Index strus::VectorStorageClient::featureIndex

(

const String &

name

)

const

Get the index starting from 0 of a feature by its name.

Parameters

[in]

name

name of the feature

Returns

index -1, if not found, else index of the feature to get the name of (index is order of insertion starting with 0)

String strus::VectorStorageClient::featureName

(

const Index &

index

)

const

Get the name of a feature by its index starting from 0.

Parameters

[in]

index

index of the feature (starting from 0)

Returns

the name of the feature defined

FloatVector strus::VectorStorageClient::featureVector

(

const Index &

index

)

const

Get the vector assigned to a feature addressed by index.

Parameters

[in]

index

index of the feature (starting from 0) return the vector

unsigned int strus::VectorStorageClient::nofConcepts

(

const String &

conceptClass

)

const

Get the number of concept features learned for a class.

Parameters

[in]

conceptClass

name identifying a class of concepts learnt.

Returns

the number of concept features and also the maximum number assigned to a feature (starting with 1)

unsigned int strus::VectorStorageClient::nofFeatures

(

)

const
