SET ALLOWED METHODS

SET ALLOWED METHODS ( methodsArray )

Parâmetro	Tipo		Descrição
methodsArray	Text array	→	Array of method names

Descrição

The SET ALLOWED METHODS command designates the project methods that can be entered via the application.

4D includes a security mechanism that filters enterable project methods from the following contexts:

• The formula editor - allowed methods appear at the end of the list of default commands and can be used in formulas (see section Description of formula editor).
• The label editor - the allowed methods are listed in the Apply menu if they are also shared with the component (see section Description of label editor).
• Fórmulas inseridas em áreas de texto com estilo ou documentos do 4D Write Pro por meio do comando ST INSERT EXPRESSION - os métodos não permitidos são automaticamente rejeitados.
• 4D View Pro documents - by default, if the VP SET ALLOWED METHODS command has never been called during the session, 4D View Pro formulas only accept methods defined by SET ALLOWED METHODS. No entanto, é recomendável usar VP SET ALLOWED METHODS. Veja Declarando o método permitido.

By default, if you do not use the SET ALLOWED METHODS command, no method is enterable (using an unauthorized method in an expression causes an error).

In the methodsArray parameter, pass the name of an array containing the list of methods to allow. The array must have been set previously.

You can use the wildcard character (@) in method names to define one or more authorized method groups.

If you would like the user to be able to call 4D commands that are unauthorized by default or plug-in commands, you must use specific methods that handle these commands.

Nota: acesso de filtragem de fórmulas pode ser desativado para todos os usuários ou para o Desenhador e Administrador através de uma opção na página de "Segurança" dos parâmetros. If the "Disabled for all" option is checked, the SET ALLOWED METHODS command will have no effect.

aviso

Esse comando filtra apenas a entrada dos métodos, não sua execução. It does not control the execution of formulas created outside the application.

Exemplo

This example authorizes all methods starting with “formula” and the “Total_general” method to be entered by the user in protected contexts:

 ARRAY TEXT(methodsArray;2)
 methodsArray{1}:="formula@"
 methodsArray{2}:="Total_general"
 SET ALLOWED METHODS(methodsArray)
