IG.Lib.SerializationDtoBase< Type, BaseType > Class Template Referenceabstract

Generic base class for Data Transfer Objects (DTO). This class is used as template for producing concrete DTO classes. Such DTOs are used for serialization and deserialization of state of various kinds of objects that need to be transfered between applications, across platforms, or simply stored in files for future use. WARNING: In most cases ISerializationDto<Type> will be used. Different BaseType and Type are used only in relatively rare cases where different derived types all have the same data that is copied to DTO. Otherwise the advantage of this can not be used because of single inheritance. More...

Detailed Description

Generic base class for Data Transfer Objects (DTO). This class is used as template for producing concrete DTO classes. Such DTOs are used for serialization and deserialization of state of various kinds of objects that need to be transfered between applications, across platforms, or simply stored in files for future use. WARNING: In most cases ISerializationDto<Type> will be used. Different BaseType and Type are used only in relatively rare cases where different derived types all have the same data that is copied to DTO. Otherwise the advantage of this can not be used because of single inheritance.

Template Parameters
TypeType for which DTO is used.
BaseTypeBase type of the type for which DTO is used, and on which copy operations will be defined. In this way, we can avoid defining these operations for each specific type, but only define them for a specific type, since operations may be similar for all derived types.

There is an agreement that all derived classes must have a public argument-less (default) constructor. Generic classes are usually not used for serialization/deserialization. Only derived types where both type parameters are fixed are normally used for this purpos. IMPORTANT: Base type is used just for being able to define copying operations only once - for the base type - and using it for different derived types. In many occasions this will not be needed, and in these occasions one should just use the derived type that does not have base type as type parameter.

Constructor & Destructor Documentation

IG.Lib.SerializationDtoBase< Type, BaseType >.SerializationDtoBase ( )
inline

Member Function Documentation

virtual bool IG.Lib.SerializationDtoBase< Type, BaseType >.GetNull ( )
inlinevirtual

Returns a flag indicating whether the object represented by the current DTO is null.

Returns
Flag indicating whether the object represented by the current DTO is null.

Implementing this as a function rather than a property prevents serialization of the flag, since the flag isn't meant to contain data, but to instruct operations that the object represented by the current DTO is null. This is useful in some scenarios where non-null DTOs are needed for null objects.

Implements IG.Lib.ISerializationDtoAux< Type >.

virtual void IG.Lib.SerializationDtoBase< Type, BaseType >.SetNull ( bool  isNull)
inlinevirtual

Sets a flag indicating whether the object represented by the current DTO is null.

Parameters
isNullIf true, this flag indicates that the object represented by the current DTO is null, although the DTO itself is not null.

Implementing this as a function rather than a property prevents serialization of the flag, since the flag isn't meant to contain data, but to instruct operations that the object represented by the current DTO is null. This is useful in some scenarios where non-null DTOs are needed for null objects.

Implements IG.Lib.ISerializationDtoAux< Type >.

abstract Type IG.Lib.SerializationDtoBase< Type, BaseType >.CreateObject ( )
pure virtual

Creates and returns a new object of the type whose data is represented by the current DTO (Data Transfer Object). WARNING: Implement thread locking in overriding functions!

Therad locking should be performed in overriding functions!

Implements IG.Lib.ISerializationDtoAux< Type >.

Implemented in IG.Lib.ListDto< ElementType, ElementBaseType, ElementDtoType >, IG.Lib.MatrixDtoBase< MatrixType >, IG.Lib.VectorDtoBase< VectorType >, IG.Lib.BoundingBoxDtoBase< BoxType >, IG.Lib.ArrayDto< ElementType, ElementBaseType, ElementDtoType >, and IG.Lib.IndexListDto.

abstract void IG.Lib.SerializationDtoBase< Type, BaseType >.CopyFromPlain ( BaseType  obj)
protectedpure virtual

Copies contents of the specified object to the current DTO (Data Transfer Object).

Parameters
objObject whose data is copied.

If the specified object is null then the _isNull property of the current DTO is set to true. Therad locking is usually not needed in overriding functions because it is normally implemeted in calling functions.

abstract void IG.Lib.SerializationDtoBase< Type, BaseType >.CopyToPlain ( ref BaseType  obj)
protectedpure virtual

Copies contents of the current DTO (Data Transfer Object) to the specified object.

Parameters
objObject that data is copied to.

If _isNull property of the current DTO is set to true then the object becomes null. Therad locking is usually not needed in overriding functions because it is normally implemeted in calling functions.

virtual void IG.Lib.SerializationDtoBase< Type, BaseType >.CopyFromBase ( BaseType  obj)
inlinevirtual

Copies data to the current DTO from an object of type BaseType.

Parameters
objObject whose data is copied to the current DTO.

Implements IG.Lib.ISerializationDto< Type, BaseType >.

virtual void IG.Lib.SerializationDtoBase< Type, BaseType >.CopyToBase ( ref BaseType  obj)
inlinevirtual

Copies data from the current DTO to an object of the base type. Object is created anew if necessary by using the CreateObject() method.

Parameters
objObject to which data is copied.

Implements IG.Lib.ISerializationDto< Type, BaseType >.

virtual void IG.Lib.SerializationDtoBase< Type, BaseType >.CopyFrom ( Type  obj)
inlinevirtual

Copies data to the current DTO from an object of type Type.

Parameters
objObject whose data is copied to the current DTO.

Implements IG.Lib.ISerializationDtoAux< Type >.

virtual void IG.Lib.SerializationDtoBase< Type, BaseType >.CopyTo ( ref Type  obj)
inlinevirtual

Copies data from the current DTO to an object of type Type. Object is created anew if necessary by using the CreateObject() method.

Parameters
objObject to which data is copied.

Implements IG.Lib.ISerializationDtoAux< Type >.

virtual void IG.Lib.SerializationDtoBase< Type, BaseType >.CopyFromObject ( object  obj)
inlinevirtual

Copies data to the current DTO from an object of type object. The necessary casts are performed.

Parameters
objObject whose data is copied to the current DTO.

Implements IG.Lib.ISerializationDto< Type, BaseType >.

virtual void IG.Lib.SerializationDtoBase< Type, BaseType >.CopyToObject ( ref object  obj)
inlinevirtual

Copies data from the current DTO to an object of type object. Object is created anew if necessary by using the CreateObject() method. The necessary casts are performed.

Parameters
objObject to which data is copied.

Implements IG.Lib.ISerializationDto< Type, BaseType >.

override string IG.Lib.SerializationDtoBase< Type, BaseType >.ToString ( )
inline

Creates and returns string representation of the current DTO (data transfer object).

This is a generic method that first copies DTO to an object that it represents, and then calls the ToString() method of that object. This solution is slow, but this method usually does not need to be faster because ToString() method is usually only used for tests of this kind of classes.
