BaseType Class Reference

#include <BaseType.h>

Inherited by PackFloat, PackLong, PackString, PackStruct, PackTreeCell, and PackULong.

List of all members.


Detailed Description

Virtual class for all AzurVeda serializable types. It is the root of all serializable classes, and actually all classes in AzurVeda Inherit from it.

All inherited objects will be able to read their values with Serialize_In(), and write it to a first call to GetSerializedDescriptionSize(), which return the size of the data to write, and then Serialize_Out() that writes it. In editable mode, each objects has direct access to ReadFile() and WriteFile() which uses the serialization.

AzurVeda Also provide a more complex Context management, through classes BaseContext and BaseObject : a BaseContext object manages a set of BaseObject. Simple BaseType are then used as class members of BaseObjects. That's why this class is also able to tell if it is a baseObject member with GetObjectThatManagesThis() , and implements methods for BaseContext edition notification.

Public Member Functions

 BaseType (void)
 Constructor.
virtual ~BaseType (void)
 Destructor.
virtual const unsigned char * Serialize_In (const unsigned char *_pDescriptionChunk)=0
 Read the object description from a byte chunk. Could crash if chunk not valid.
virtual unsigned int GetSerializedDescriptionSize (void)=0
 get the size of the whole byte chunk that will be written by Serialize_Out().
virtual unsigned char * Serialize_Out (unsigned char *_pDescriptionChunkToFill)=0
 write the Current object definition to a Chunk using private packed types, recursively.
virtual unsigned int WriteFile (const char *_pFileName)
 write a serialized form, using GetSerializedDescriptionSize() and Serialize_Out().
virtual unsigned int ReadFile (const char *_pFileName)
 Try to read a serialized form, using Serialize_In().
virtual void SetObjectThatManagesThis (BaseObject *_pManager)
 The Object this one belong to as a member. Should only be used at init.
void SetMemberName (const char *_MemberName)
 Explicits the name of an object when used as a class member. It exists only in editable mode, and then can be used by any GUI. A member with an infoString not NULL, should be drawn in a GUI and receive updates. an object member with GetMemberName() returning NULL should not be edited by an interface or undo-managed. Use REGISTER_MEMBER macros family: it registers the members and use SetMemberName() automatically (or not, according to the compilation mode).
const char * GetMemberName () const
 Explicits the name of an object when used as a class member. It exists only in editable mode, and then can be used by any GUI. A member with an infoString not NULL, should be drawn in a GUI and receive updates. an object member with GetMemberName() to NULL should not be edited by an interface or undo-managed. set with SetMemberName().
void SetMemberInfo (const char *_MemberInfo)
 Explicits the use of an object when used as a class member. It should explain what the member does for the object. It exists only in editable mode,and can be used by any GUI. Don't use html tags , only \n are allowed. Use REGISTER_MEMBER_INFO macro after the REGISTER_MEMBER macro in the constructors. It can be left NULL.
const char * GetMemberInfo () const
 Explicits the use of an object when used as a class member. It exists only in editable mode and can be used by any GUI. It should explain what the member does for the object.
virtual const char * GetClassID () const =0
 Each BaseType's inherited classes must explicit an ID for their class, or let use one of the super class at least through this virtual method. This is needed by GUIs to detect the types of each sub-members, and shape an interface for each Object according to their member list.
virtual const char * ValueToString ()
 convert the value of this object to an explicit string. The object manages the string privately, so just read it or copy it. the string would be destroyed with the objects, and changed when using Set() methods.
BaseObjectGetObjectThatManagesThis ()
 If there is any, get the object that manages this one as a member.
void MakeCloneOf (BaseType &_ModelObject)
 Tool that makes an object take the values of another using serialization. Use with care: You got to clone a PackUlong with a PackULong, a PackString with a PackString: Clone Object of the same type or it will crash . A test is done at the beginning to check that for both types are the sames, if not it does nothing. however it may still crash with 2 objects from unherited classes. Also, some type like PackObjectReference, will not clone its value by copying a pointer.Reference member clonage is done with BaseObject::Clone().

Protected Member Functions

void BeginChangeNotification ()
 In edition mode, when a member of an object is changed (like in a Set()), you got to use BeginChangeNotification(), make your changes, and then EndChangeNotification(), so that the edition of this object and member is known by the context, and allows it to manage a GUI update and the undo stack.
void EndChangeNotification ()
 In edition mode, when a member of an object is changed (like in a Set()), you got to use BeginChangeNotification(), make your changes, and then EndChangeNotification(), so that the edition of this object and member is known by the context, and allows it to manage a GUI update and the undo stack.

Protected Attributes

 an object can belong (or not) to a BaseObject,( and to a BaseContext through it).
const char * m_pMemberName

Member Enumeration Documentation

enum eVedaUpdate
 

enum used by BaseContext::NotifyObjectChange() to describe the notification meaning. Used by interfaces to monitor a context.

Enumerator:
eVedaUpdate_NoUpdate  0 means No Update.
eVedaUpdate_MemberIsGoingToChange  Sent before a BaseObject member value change.( in order to lock the context to prevent object use from other thread.).
eVedaUpdate_MemberChanged  a member of a BaseObject just changed.
eVedaUpdate_MemberChangedBecauseOfUndo  a member of a BaseObject just changed, but because of an undo. you may treat it the same as eVedaUpdate_MemberChanged.
eVedaUpdate_MemberDestroyed  Member of object Destroyed ! Watch out, the ID of the member is a dead pointer.
eVedaUpdate_ObjectNew  new BaseObject created.
eVedaUpdate_ObjectDestroyed  BaseObject just destroyed.Watch out, the ID of the object is a dead pointer.
eVedaUpdate_ObjectReCreated  an object has just been Created; It's state has changed!
eVedaUpdate_ObjectClosed  an object has just been closed; It's state has changed!
eVedaUpdate_NewRegisteredClass  TODO: a new class has been registered to the context.
