//| AiCode.mqh |
//| Parser de archivos .set usando formato TAPE (estilo simdjson): |
//| toda la estructura parseada vive en UN SOLO array plano |
//| long m_tape[], sin objetos CSetParam/CSetValue2. Elimina el |
//| overhead de construccion/gestion de objetos por linea. |
//| |
//| FORMATO DEL TAPE: |
//| tape[0] = cantidad total de nodos (lineas parseadas) |
//| Por cada nodo, a partir de tape[1], en secuencia: |
//| [Key slot] (keyStart<<32)|keyLen |
//| [Metadata slot] bit63=isOptimizable, bit62=enabled |
//| [Value slot(s)] 1 valor si Simple, 4 valores (Valor/Start/ |
//| Step/Stop) seguidos si Optimizable. |
//| Cada valor individual ocupa: |
//| - 1 slot si STRING o BOOL |
//| - 2 slots si DOUBLE (tag + bits crudos) |
//| tag = 4 bits altos del primer slot del |
//| valor (0=STRING,1=DOUBLE,2=BOOL) |
//| |
//| Uso identico al de siempre para el caller: |
//| CSetFileParser setfile; |
//| setfile.AssignString(g_setfile); |
//| if(setfile.Parse()) |
//| { |
//| int x = setfile["MaxOrders_18"].Valor().ToInt(); |
//| int st = setfile["MaxOrders_18"].Step().ToInt(); |
//| } |
