Member Function Documentation

_createCompressor()

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

staticprotected

Builds a data compressor instance from a runtime type, even if it is not registered.

Parameters

rtType	Must be the valid runtime type of the class to be registered. The compressor class must be derived from DataCompressor.
err	Returns ML_RESULT_OK in case of success; otherwise, it returns a code describing the problem.

Returns

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

_findCompressorType() [1/2]

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

staticprotected

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

Parameters

rtType

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]

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

staticprotected

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

Parameters

typeName

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()

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. For an empty typeName string, NULL is always returned.

Parameters

typeName	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]

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

static

Searches a compressor with type name and returns its corresponding registration entry.

Parameters

rtType

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]

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

static

Searches a compressor with type name and returns its corresponding registration entry.

Parameters

typeName

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()

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

static

Returns a list of all names of currently registered DataCompressors.

getRegisteredDataCompressors()

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

static

Provides constant access to the list of available DataCompressors.

registerCompressor()

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()

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

static

Removes a registered data compressor.

Parameters

rtType

The runtime type of the class to be unregistered.

Returns

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