Features connection, the Association, its generation and use example

According to base article metalowymi compositions are similar:

Composition

the Generation of SQL DDL

The structure definition DDL SQL is created like this:

  • The table corresponding to dealova class foreign key to the table corresponding cap;
  • Constraint linking table.

Generation .Net language

Described in detail in class Structure of the data objects.

Basic:

  1. In the class-detaile generated property assigned .Net attribute AgregatorAttribute private member, both of type class шапки;
  2. Storage metalowych sets of objects is generated by a special class that inherits from DetailArray;
  3. In the class header generated property and private member declared by a type spec.class - successor from DetailArray.

Additional editable properties

Properties composition (PTP link):

Description

Description metalowego properties.

Generation .Net language

Description (DocComment) the properties of array access metalowych objects class header

StartRole

The name of the role from the beginning of the track that duplicates the role name in the diagram

the Generation of SQL DDL

In the CREATE TABLE of the table of detail generates a field definition for the foreign key with the same name.

Generation .Net language

The name of the property-aggregator in the class-detaile.

StartMultiplicity

The multiplicity from the beginning of the Association, the duplicates on the chart. Can take any value, however, the generation can only be 1. If another value, the generation will stop with an error.

EndRole

The name of the role from the end of a song

Generation .Net language

The name of the property and private member class header

EndRoleStored

Generation .Net language

Private member class header is not generated and the code of the get and set accessors in a property remains empty (just brackets programmer every accessor)

Aggregator AutogenerateTypeUsage

Automatic generation of the types used for aggregator (header) in the class-detaile.

Automatic generation works as follows:

  1. Finds all successors of the aggregator (within stage);
  2. Classes were found, together with the aggregator, sorted by name on возрастанию;
  3. The result is the definition of used types.

the Generation of SQL DDL

In DDL table definition for class detail foreign keys are generated for each found class. The fields are named as follows:

<AggregatorStorage>_M<ПорядкНомерВTypeUsage>

ПорядкНомерВTypeUsage» «— starts at 0.

Generation .Net language

The property that specifies the aggregator, metalowego of the class .NET-attribute TypeUsageAttribute, showing all the found classes.

Aggregator A Typeusage

Used for aggregator (header) in the class-detaile.

Is ignored if the flag is Aggregator AutogenerateTypeUsage

You can specify the names of the used types (the names of the aggregator and any of his heirs, for which should be relevant to this dealova Association), separated by commas.

the Generation of SQL DDL

In DDL table definition for class detail generated foreign keys for each of the classes. The fields are named as follows:

<AggregatorStorage>_M<ПорядкНомерВTypeUsage>

ПорядкНомерВTypeUsage» «— starts at 0.

Generation .Net language

The property that specifies the aggregator, metalowego of the class .NET-TypeUsageAttribute attribute, indicating the specified classes.

AggregatorStorage

The name of the storage properties of the aggregator metalowego class.

the Generation of SQL DDL

If specified, this will be the field name of the foreign key in the table, respectively. class-detailw, not StartRole.

Generation .Net language

Before defining the properties, pointing to the aggregator in dealova class is generated by specifying attribute PropertyStorageAttribute (Namespace: ICSSoft.STORMNET, Assembly: ICSSoft.STORMNET.DataObject (in ICSSoft.STORMNET.DataObject.dll))

Detail AutogenerateTypeUsage

Automatic generation of the types used for detail class header.

Automatic generation works as follows:

  1. Finds all successors of detail (within stage);
  2. Classes were found, together with detaila are sorted by name by возрастанию;
  3. The result is the definition of used types.

Generation .Net language

Property pointing to an array metalowych objects class-hats, is prescribed .NET-TypeUsageAttribute attribute, indicating the specified classes.

Detail A Typeusage

Used for detail class header.

Generation .Net language

Property pointing to an array metalowych objects class-hats, is prescribed .NET-attribute TypeUsageAttribute, showing all the found classes.

PBAggregatorCustomAttributes

Generation .Net language

If the option specified is generated bracket programmer for manual application .Net attributes before the code properties of the aggregator in detaile.

PBAggregatorGetEnd

Generation .Net language

If the option specified is generated bracket programmer for manual entering of code before the end of the getter properties of the aggregator in detaile.

PBAggregatorGetStart

Generation .Net language

If the option specified is generated bracket programmer to “manual” any code after the beginning of getter properties of the aggregator in detaile.

PBAggregatorSetEnd

Generation .Net language

If the option specified is generated bracket programmer for manual entering of code before the end of the set accessors of properties of the aggregator in detaile.

PBAggregatorSetStart

Generation .Net language

If the option specified is generated bracket programmer for manual entering the code after the set accessor of the property-aggregator in detaile.

PBDetailCustomAttributes

Generation .Net language

If the option specified is generated bracket programmer for manual application .Net attributes before the code properties, indicate the array metalowych objects.

PBDetailGetEnd

Generation .Net language

If the option specified is generated bracket programmer for manual entering of code before the end of the getter of a property that identifies an array metalowych objects.

PBDetailGetStart

Generation .Net language

If the option specified is generated bracket programmer to “manual” any code after the beginning of getter properties that points to an array metalowych objects.

PBDetailSetEnd

Generation .Net language

If the option specified is generated bracket programmer for manual entering of code before the end of the set accessor of a property that identifies an array metalowych objects.

PBDetailSetStart

Generation .Net language

If the option specified is generated bracket programmer for manual entering the code after the set accessor of a property that identifies an array metalowych.
