See also: Info, InfoMap

Enumerator
validation_info	Validation Info.
validation_service_info	Validation Info Service.
type_info	Type Info.

◆ TypeOfType

invalid_type	the type is unknown
data_type	the type is a data type (DataType)
enum_type	the type is a enum type (EnumType)

unit	the unit is a unit (Unit)
base_unit	the unit is a base unit (BaseUnit)

Definition at line 76 of file dd_common_types.h.

◆ ValidationLevel

enum class ValidationLevel : uint8_t

strong

Validation level.

Enumerator
dont_know	The validation is not known. This means it is not calculated yet. Use i.e. validate
invalid	the validation level is invalid, dependencies can not be obtained or the dependency "to" is invalid (struct to struct i.e.).
good_enough	Structs and elements can be "good_enough" for the TypeInfo. This means the Coder and Decoder can calculate the sizes and the all access Functions can obtain values. Usually this should be the valid state. The problem is, that there are DataDefinition out there (in the users world) using i.e. units, but does not define the unit within that DD. At this point we do not want to break that code! So good enough means: Not well defined in some cases, but good enough for calculate byte positions and TypeInfo. Only structs, enums and datatypes may have a validationlevel of "good_enough" if there are any other DD Objects used in a DataDefinition and they are "invalid", the DD will also set to "invalid"!
valid	every thing is well defined.

Function Documentation

◆ addStreamTypeByName()

bool addStreamTypeByName	(	const std::string &	stream_type_name,
		const DataDefinition &	source_dd,
		DataDefinition &	destination_dd )

Merges or add the streamtype with the name of stream_type_name.

If there are dependencies, they will be retrieved from source_dd.
following types are considered:

StructType
StreamMetaType

Remarks: This functionality was designed to support adding types that are part of the streams (Stream).

Parameters

stream_type_name	the typename of the type to add.
source_dd	dependencies will be obtained from this DataDefinition reference (streammetatype, structtype, etc.)
destination_dd	where to add or merge

Exceptions

ddl::dd::Error throws if the type already exists and is not equal to the given one. Will also check dependencies.

Return values

true	a type was found and added
false	a type was NOT found and so NOT added

◆ addTypeByName()

bool addTypeByName	(	const std::string &	type_name,
		const DataDefinition &	source_dd,
		DataDefinition &	destination_dd )

Helper function which merges or adds the type with the name of type_name.

If there are dependencies, they will be retrieved from source_dd.
following types are considered:

DataType
EnumType
StructType

Remarks: This functionality was designed to support adding types that are part of the elements within a StructType.

Parameters

type_name	the typename of the type to add.
source_dd	dependencies will be obtained from this DataDefinition reference (other streammetatype)
destination_dd	where to add or merge

Exceptions

ddl::dd::Error throws if the type already exists and is not equal to the given one. Will also check dependencies.

Return values

true	a type was found and added
false	a type was NOT found and so NOT added

◆ addUnitByName()

bool addUnitByName	(	const std::string &	unit_name,
		const DataDefinition &	source_dd,
		DataDefinition &	destination_dd )

Merges or add the unit with the name of unit_name.

If there are dependencies, they will be retrieved from source_dd.
following types are considered:

Parameters

unit_name	the unitname of the unit to add.
source_dd	dependencies will be obtained from this DataDefinition reference (baseunit, unitprefix)
destination_dd	where to add or merge

Exceptions

ddl::dd::Error throws if the unit already exists and is not equal to the given one. Will also check dependencies.

Return values

true	a unit was found and added
false	a unit was NOT found and so NOT added

◆ transformProblemList()

std::vector< std::string > transformProblemList ( const std::vector< Problem > & problems )

transforms the Problem List to a simple vector of strings.

Simple usage:

//...
 
using namespace ddl;
dd::DataDefinition my_dd;
//... adding ... loading ... using
std::cout <<
a_util::strings::join(dd::transformProblemList(my_dd.getValidationProtocol()),"\n");

Parameters

problems the problems to tranform.

Returns: std::vector<std::string>

◆ transformValidationProblemList()

std::vector< std::string > transformValidationProblemList ( const std::vector< ddl::dd::Problem > & problems )

transforms the validation protocol of problems to a simple vrctor of strings.

Simple usage:

//...
 
using namespace ddl;
dd::DataDefinition my_dd;
//... adding ... loading ... using
std::cout <<
a_util::strings::join(dd::transformValidationProblemList(my_dd.getValidationProtocol()),"\n");

Parameters
