Member Function Documentation

◆ _createCompressor()

static DataCompressor* ml::DataCompressorFactory::_createCompressor	(	const RuntimeType *	rtType,
		MLErrorCode &	err
	)

staticprotected

Build a data compressor instance from a RumtimeType, even if it is not registered.

Parameters

rtType	must be the valid RuntimeType of the class to be registered The compressor class must be derived from DataCompressor.
err	returns ML_RESULT_OK in case of success, otherwise a code describing the problem.

Returns: A pointer to an instance of the compressor or NULL in error cases.

◆ _findCompressorType() [1/2]

static std::vector<CompressionRegisterEntry>::iterator ml::DataCompressorFactory::_findCompressorType ( const RuntimeType & rtType )

staticprotected

Search a compressor with type name and return its corresponding registration entry.

Parameters

rtType is the Runtime type of the compressor class to find.

Returns: An iterator to the instance of the registered data compressor or _dataCompressorTypes.end() on failure.

◆ _findCompressorType() [2/2]

static std::vector<CompressionRegisterEntry>::iterator ml::DataCompressorFactory::_findCompressorType ( const std::string & typeName )

staticprotected

Search a compressor with type name and return its corresponding registration entry.

Parameters

typeName is the name of the of the compressor class to find.

Returns: An iterator to the instance of the registered data compressor or _dataCompressorTypes.end() on failure.

◆ createCompressor()

static DataCompressor* ml::DataCompressorFactory::createCompressor	(	const std::string &	typeName,
		MLErrorCode *	errCode = `nullptr`
	)

static

Factory and registration support for data compressors.

Creates a compressor of a given type or NULL on failure, for example if the type does not exist. The created instance must be deleted with delete. On an empty typeName string always NULL is returned.

Parameters

typeName	is the registered name of the compressor type to be created.
errCode	will be ignored if NULL (the default). If non NULL it will return ML_RESULT_OK in case of success or another error code to describe the reason for the failure.

Returns: A pointer to a new instance of the registered data compressor or NULL on failure.

◆ findCompressorTypeConst() [1/2]

static std::vector<CompressionRegisterEntry>::const_iterator ml::DataCompressorFactory::findCompressorTypeConst ( const RuntimeType & rtType )

static

Search a compressor with type name and return its corresponding registration entry.

Parameters

rtType is the Runtime type of the compressor class to find.

Returns: A constant iterator to the instance of the registered data compressor or _dataCompressorTypes.end() on failure.

◆ findCompressorTypeConst() [2/2]

static std::vector<CompressionRegisterEntry>::const_iterator ml::DataCompressorFactory::findCompressorTypeConst ( const std::string & typeName )

static

Search a compressor with type name and return its corresponding registration entry.

Parameters

typeName is the name of the of the compressor class to find.

Returns: A constant iterator to the instance of the registered data compressor or _dataCompressorTypes.end() on failure.

◆ getRegisteredDataCompressorNames()

static std::vector<std::string> ml::DataCompressorFactory::getRegisteredDataCompressorNames ( )

static

Returns list of all names of currently registered DataCompressors.

◆ getRegisteredDataCompressors()

static const std::vector<CompressionRegisterEntry>& ml::DataCompressorFactory::getRegisteredDataCompressors ( )

static

Provides constant access to the list of available DataCompressors.

◆ registerCompressor()

static MLErrorCode ml::DataCompressorFactory::registerCompressor ( const RuntimeType * rtType )

static

Registers a data compressor.

Parameters

rtType must be the valid RuntimeType of the class to be registered The compressor class must be derived from DataCompressor.

Returns: ML_RESULT_OK in case of success or a code describing the nature of the error.

◆ unregisterCompressor()

static MLErrorCode ml::DataCompressorFactory::unregisterCompressor ( const RuntimeType & rtType )

static

Remove a registered data compressor.

Parameters

rtType is the RuntimeType of the class to be unregistered.

Returns: ML_RESULT_OK on successful unregistration of the compressor type or an MLErrorCode describing the problem.
