Detailed Description

Base class for all object containers.

The reason for the existence of this class is that code that uses the reflection functionality must be able to get hold of members of items.

Member Function Documentation

◆ GetMember() [1/2]

virtual const ContainerBase & Safir::Dob::Typesystem::ObjectContainerBase::GetMember	(	const int	member,
		const int	index ) const

pure virtual

Get a const reference to a member container from an object.

Use the methods in Members to get member indices and array sizes for use with this method.

Note: Do not use this method unless you're very sure it is the one you need!

Parameters

member	[in] - The index of the member to get.
index	[in] - The array index of the member to get.

Returns: A const reference to the member container.

Exceptions

IllegalValueException	If the index is not in the range of the array.
SoftwareViolationException	If the element is not an array and the index is not 0.

References Safir::Dob::Typesystem::ContainerBase::ContainerBase().

Here is the call graph for this function:

◆ GetMember() [2/2]

virtual ContainerBase & Safir::Dob::Typesystem::ObjectContainerBase::GetMember	(	const int	member,
		const int	index )

pure virtual

Get a reference to a member container from an object.

Use the methods in Members to get member indices and array sizes for use with this method.

Note: Do not use this method unless you're very sure it is the one you need!

Parameters

member	[in] - The index of the member to get.
index	[in] - The array index of the member to get.

Returns: A reference to the member container.

Exceptions

IllegalValueException	If the index is not in the range of the array.
SoftwareViolationException	If the element is not an array and the index is not 0.

References Safir::Dob::Typesystem::ContainerBase::ContainerBase().

Here is the call graph for this function:

◆ GetObjectPointer()

virtual const ObjectPtr Safir::Dob::Typesystem::ObjectContainerBase::GetObjectPointer ( ) const

pure virtual

Get a smart pointer to the contained object.

This method will cast the smart object pointer to the derived type contained by the container to a smart pointer to an Object (the DOB object base class.

This method does not check if the container is null!

Note: Do not use this method unless you're very sure it is the one you need!

Returns: A smart pointer to the contained object.

◆ IsChangedHere()

bool Safir::Dob::Typesystem::ObjectContainerBase::IsChangedHere ( ) const

Is the change flag in the container set?

This method is like IsChanged without the recursion (on object containers IsChanged is recursive).

Returns: True if the containers change flag is set.

References Safir::Dob::Typesystem::ContainerBase::m_bIsChanged.

◆ operator=()

ObjectContainerBase & Safir::Dob::Typesystem::ObjectContainerBase::operator= ( const ObjectContainerBase & other )

protected

Copy assignment operator.

Parameters

other [in] - The object to copy.

Returns: A reference to this.

References ObjectContainerBase(), and Safir::Dob::Typesystem::ContainerBase::operator=().

Here is the caller graph for this function:

◆ ResetObjectPointer()

virtual void Safir::Dob::Typesystem::ObjectContainerBase::ResetObjectPointer ( )

pure virtual

Reset (ie set to null) the contained pointer.

Warning: This method does not update the change flag!

Note: Do not use this method unless you're very sure it is the one you need!

◆ SetChangedHere()

void Safir::Dob::Typesystem::ObjectContainerBase::SetChangedHere ( const bool changed )

Set the change flag in the container.

This method is like SetChanged without the recursion (on object containers SetChanged is recursive).

Parameters

changed [in] - The value to set the change flag to.

References Safir::Dob::Typesystem::ContainerBase::m_bIsChanged.

◆ SetObjectPointer()

virtual void Safir::Dob::Typesystem::ObjectContainerBase::SetObjectPointer ( const ObjectPtr ptr )

pure virtual

Set the smart pointer in the container.

This method will set the contained pointer to point to another object. Checks are NOT always made to see that it is of the correct type.

Warning: This method does not update the change flag!

Note: Do not use this method unless you're very sure it is the one you need!

Parameters

ptr	[in] A pointer to the new object to point to.

◆ SetPtr()

virtual void Safir::Dob::Typesystem::ObjectContainerBase::SetPtr ( const ObjectPtr & ptr )

pure virtual

Set the smart pointer in the container.

This method will set the contained pointer to point to another object. Checks are always made to see that it is of the correct type. The change flag of the container will be updated.

Parameters

ptr	[in] A pointer to the new object to point to.

Exceptions

IncompatibleTypesException If the ptr is not of the type contained by the container.
