From 99955c78f63d1cb0d8bec666bc33953590a74c8a Mon Sep 17 00:00:00 2001 From: jaybinks Date: Thu, 1 Nov 2007 23:22:01 +0000 Subject: fixed failed builds build:USDX-LAZLIN-75 build:USDX-LAZLIN-76 for some reason we can not use {$MODE Delphi} in an included file. ( Probably because of the way the compier scopes this switch to each pas file ) ive had to revert this part of eddies changes. git-svn-id: svn://svn.code.sf.net/p/ultrastardx/svn/trunk@548 b956fd51-792f-4845-bead-9b4dfca2ff2c --- Game/Code/Classes/UServices.pas | 647 ++++++++++++++++++++-------------------- 1 file changed, 326 insertions(+), 321 deletions(-) (limited to 'Game/Code/Classes/UServices.pas') diff --git a/Game/Code/Classes/UServices.pas b/Game/Code/Classes/UServices.pas index 92b61e85..c8761df0 100644 --- a/Game/Code/Classes/UServices.pas +++ b/Game/Code/Classes/UServices.pas @@ -1,321 +1,326 @@ -unit UServices; - -interface - -{$I switches.inc} - -uses uPluginDefs, SysUtils; -{********************* - TServiceManager - Class for saving, managing and calling of Services. - Saves all Services and their Procs -*********************} - -type - TServiceName = String[60]; - PServiceInfo = ^TServiceInfo; - TServiceInfo = record - Self: THandle; //Handle of this Service - Hash: Integer; //4 Bit Hash of the Services Name - Name: TServiceName; //Name of this Service - - Owner: Integer; //If < 0 [-(DLLMan Pluginindex + 1)]; 0 - undefined, On Error Full shutdown, If < 0 [ModuleIndex - 1] - - Next: PServiceInfo; //Pointer to the Next Service in teh list - - //Here is s/t tricky - //To avoid writing of Wrapping Functions to offer a Service from a Class - //We save a Normal Proc or a Method of a Class - Case isClass: boolean of - False: (Proc: TUS_Service); //Proc that will be called on Event - True: (ProcOfClass: TUS_Service_of_Object); - end; - - TServiceManager = class - private - //Managing Service List - FirstService: PServiceInfo; - LastService: PServiceInfo; - - //Some Speed improvement by caching the last 4 called Services - //Most of the time a Service is called multiple times - ServiceCache: Array[0..3] of PServiceInfo; - NextCacheItem: Byte; - - //Next Service added gets this Handle: - NextHandle: THandle; - public - Constructor Create; - - Function AddService(const ServiceName: PChar; const Proc: TUS_Service = nil; const ProcofClass: TUS_Service_of_Object = nil): THandle; - Function DelService(const hService: THandle): integer; - - Function CallService(const ServiceName: PChar; const wParam, lParam: dWord): integer; - - Function NametoHash(const ServiceName: TServiceName): Integer; - Function ServiceExists(const ServiceName: PChar): Integer; - end; - -var - ServiceManager: TServiceManager; - -implementation -uses UCore; - -//------------ -// Create - Creates Class and Set Standard Values -//------------ -Constructor TServiceManager.Create; -begin - FirstService := nil; - LastService := nil; - - ServiceCache[0] := nil; - ServiceCache[1] := nil; - ServiceCache[2] := nil; - ServiceCache[3] := nil; - - NextCacheItem := 0; - - NextHandle := 1; - - {$IFDEF DEBUG} - WriteLn('ServiceManager: Succesful created!'); - {$ENDIF} -end; - -//------------ -// Function Creates a new Service and Returns the Services Handle, -// 0 on Failure.
