//Classe: TAlteradorBD //
//Descrição: A idéia geral desta classe é evitar que se escreva muitas sentenças //
// SQL simples. Assim, baseando-se em três listas a classe deve controlar inserções//
// e atualizações no banco de dados. Esta classe depende do SQLMainData para //
// funcionar. Existem três listas: //
// 1) nomesCampos: lista de nomes de todos os campos de uma tabela que //
// interessam para a atualização que está sendo feita //
// 2) nomesChaves: lista de nomes de todos os campos da lista de campos que //
// deverão ser tratados como chave //
// 3) valoresCampos: lista paralela à lista de nomes de campos que diz respeito//
// aos valores correspondentes aos campos //
// Além das listas, existe uma propriedade (nomeTabela) que representa o nome da //
// tabela que está sendo atualizada pelo objeto. //
// Existem 3 métodos públicos além do construtor e do destrutor: //
// 1) existeRegistro: baseado nas informações contidas nas listas, verifica se //
// já existe um registro correspondente (no que diz respeito//
// às chaves) no BD. //
// 2) inserir: insere o registro no BD. Caso o registro já exista no BD e a //
// propriedade sobreescrever esteja setada para true, gera um //
// update para a tabela. //
// 3) adicionarCampo: é o meio com que os campos são adicionados ao objeto //
//**********************************************************************************//

{: GLObjectManager<p>
The object manager is used for registering classes together with a category,
description + icon, so that they can be displayed visually. This can then
be used by run-time or design-time scene editors for choosing which
scene objects to place into a scene.<p>
TODO: add some notification code, so that when a scene object is registered/
unregistered, any editor that is using the object manager can be notified.
<b>History : </b><font size=-1><ul>
<li>11/11/09 - DaStr - Improved FPC compatibility
(thanks Predator) (BugtrackerID = 2893580)
<li>25/07/09 - DaStr - Added $I GLScene.inc
<li>26/03/09 - DanB - Added PopulateMenuWithRegisteredSceneObjects procedure.
<li>14/03/09 - DanB - Created by moving TObjectManager in from GLSceneRegister.pas,
made some slight adjustments to allow resources being loaded
from separate packages.
