* TPublic()
* Clase para el reemplazo de Variables Publicas
* Version 5.2b - 01/04/2006
*
* Oscar Chacon
* ventas@busmatic.com
* http://www.busmatic.com
*
* Aportes: [ER] Ray Islas
* DATAS
* -----------------------------------------------------------------------------
* aVars - Arreglo de variables
* cName - Nombre ultima variable accedida
* nPos - Valor ultimo variable accedida
* automata - Asignación automatica, por defecto TRUE [WA]
*
* METODOS
* -----------------------------------------------------------------------------
* New() - Contructor
* Add() - Agrega/define nueva variable
* Del() - Borra variable
* Get() - Accede a una veriable directamente
* Set() - Define nuevo valor directamente
* GetPos() - Obtener la posición en el array
* Release() - Borra todas las variables
* IsDef() - Chequea si una variable fue definida
* Clone() - Clona la DATA aVars
* nCount() - Devuelve cantidad de variables definidas
* Save() - Salva DATA aVars
* Restore() - Restaura DATA aVars
*
* NOTA
* -----------------------------------------------------------------------------
* Para acceder al valor de una variable, se puede hacer de 2 formas,
* una directa usando oPub:Get("Codigo") o por Prueba/Error oPub:Codigo,
* este último es mas simple de usar pero más lento.
*
* Para definir un nuevo valor a una variable tambien puede ser por 2 formas,
* directamente por oPub:Set("Codigo", "ABC" ), o por Prueba/Error
* oPub:Codigo := "ABC".
*
* Atencion: Los metodos Get() y Set() no controlan si la variable existe,
* para ganar en velocidad.
*
* Las variables definidas NO son case sensitive.
*
* MODIFICACIONES Y AGREGADOS
* -----------------------------------------------------------------------------
* 2.2b Correción Bug en metodo Add() sobre FWH.
* 2.2a Modificado para não restringir o número de variáveis em [x]Harbour [WA]
* 2.2 Modificada para funcionar en [x]Harbour
*
* 2.1 Se guarda el Nombre y Posición de la última variable accedida para incrementar
* la velocidad. (Implementado por Eduardo Rizzolo)
*
* EJEMPLO
* -----------------------------------------------------------------------------
* FUNCTION Test()
* local oP := TPublic():New(), aSave, nPos
*
* oP:Add("Codigo") // Defino variable sin valor inicial
* oP:Add("Precio", 1.15) // Defino variable con valor inicial
* oP:Add("Cantidad", 10 )
* oP:Add("TOTAL" )
*
* // Acceso a variables por prueba/error
* oP:Total := oP:Precio * oP:Cantidad
*
* // Definicion y Acceso a variables directamente
* oP:Set("Total", oP:Get("precio") * oP:Get("CANTIDAD") )
*
* oP:Del("Total") // Borro una variable
* ? oP:IsDef("TOTAL") // Varifico si existe una variable
*
* nPos := oP:GetPos("Total") // Obtengo la posición en el array
* oP:aVars[nPos,2] := 0 // Modifico el Valor en el array directo
*
* aSave := oP:Save() // Guardo las Variables
* oP:Release() // Borro TODAS las variables
* oP:Restore( aSave ) // Restauro las variables
*
* oP:End() // Termino
*
* RETURN NIL
*
* EXEMPLO (Asignación Automática)
*
* FUNCTION MAIN()
* LOCAL oP:=TPublic():New(.T.)
*
* op:nome := "Wilson Alves"
* op:Endereco := "Rua dos Cravos,75"
* op:Cidade := "Londrina-PR"
* op:Celular := "9112-5495"
* op:Empresa := "WCW Software"
*
* ? op:Nome,op:Endereco,op:Cidade,op:celular,op:empresa
