Detailed Description

Mother class for data wrapper template class.

This class is the base class for data wrappers used by the DataMap class. It is used to provide a common base class wrapper for every kind of object, in order to create containers of different objects, using the type erasure pattern.

Member Function Documentation

CloneObject()

virtual std::unique_ptr<ObjectWrapperBase> EA::ObjectWrapperBase::CloneObject ( )

pure virtual

Clones the wrapped object and wraps it.

Creates a wrapper wrapping a clone of the wrapped object.

Returns

pointer to the wrapper wrapping the cloned object.

Implemented in EA::ObjectWrapperT< DataType, typename std::enable_if< smart_is_copy_constructible< DataType >::value >::type >, and EA::ObjectWrapperT< DataType, typename >.

CloneWrapper()

virtual std::unique_ptr<ObjectWrapperBase> EA::ObjectWrapperBase::CloneWrapper ( )

pure virtual

Clones the wrapper.

Creates a new wrapper wrapping the same object.

Returns

pointer to the clone wrapper.

Implemented in EA::ObjectWrapperT< DataType, typename std::enable_if< smart_is_copy_constructible< DataType >::value >::type >, and EA::ObjectWrapperT< DataType, typename >.

GetObjAddress()

virtual void* EA::ObjectWrapperBase::GetObjAddress ( )

pure virtual

Getter for raw pointer to the wrapped object.

Returns

the address of the wrapped object.

Implemented in EA::ObjectWrapperTImpl< DataType >.

GetObjType()

virtual const std::type_info& EA::ObjectWrapperBase::GetObjType ( )

pure virtual

Returns the type of the wrapped object.

Implemented in template derived classes #ObjectWrapperT.

Returns

the type of the wrapped object.

Implemented in EA::ObjectWrapperTImpl< DataType >.

IsPolymorphic()

virtual bool EA::ObjectWrapperBase::IsPolymorphic ( )

pure virtual

Test for polymorphic wrapped object.

Returns

true if the wrapped object is of a polymorphic class.

Implemented in EA::ObjectWrapperTImpl< DataType >.

WrapNothing()

virtual void EA::ObjectWrapperBase::WrapNothing ( )

pure virtual

Remove the wrapped object.

Makes the wrapper wrap no object. An eventual previously wrapped object will be deleted if the object is owned by the wrapper.

Implemented in EA::ObjectWrapperTImpl< DataType >.

WrapObject()

virtual bool EA::ObjectWrapperBase::WrapObject ( void *  address, const std::type_info &  type, bool  own  )

pure virtual

Wrap the object at the given address.

Set the wrapped object. This method should be used only in those rare cases where the object is available only through a void*. Type check is enforced through the #type argument.

Parameters

address	The address of the object to be wrapped.
type	The type of the object at the given address.
own	if true then the wrapper will own the wrapped object.

Returns

true if the object at the given address has been correctly wrapped.

Implemented in EA::ObjectWrapperTImpl< DataType >.

WrapsSomething()

virtual bool EA::ObjectWrapperBase::WrapsSomething ( )

pure virtual

Checks if the wrapper wraps something.

Returns

true if the wrapped pointer is not nullptr.

Implemented in EA::ObjectWrapperTImpl< DataType >.
