DEV_ESSENTIAL_DEPRECATED_CODEC_FACTORY CodecFactory ( const std::string & struct_name,
const std::string & dd_string )

Constructor that take a DataDefinition string for initialization.

Parameters
[in]struct_nameThe name of the struct for which codecs should be generated.
[in]dd_stringThe DataDefinition description within a (xml)string.

◆ CodecFactory() [3/5]

DEV_ESSENTIAL_DEPRECATED_CODEC_FACTORY CodecFactory ( const ddl::dd::StructType & struct_type,
const dd::DataDefinition & dd )

Constructor that uses an OO-DataDefinition struct for initialization.

Parameters
[in]struct_typeThe struct definition.
[in]ddThe DD

◆ CodecFactory() [4/5]

DEV_ESSENTIAL_DEPRECATED_CODEC_FACTORY CodecFactory ( const ddl::dd::StructTypeAccess & struct_type_access)

Constructor that uses an valid struct type access for initialization.

Parameters
[in]struct_type_accessThe struct type access.

◆ CodecFactory() [5/5]

DEV_ESSENTIAL_DEPRECATED_CODEC_FACTORY CodecFactory ( const DDStructure & dd_struct)

Constructor that uses an OO-DataDefinition struct for initialization.

Parameters
