Member Function Documentation

◆ FixPointers()

virtual void ChunkHandler::FixPointers ( ) const

inlinevirtual

Fix the pointers.

Pointers are saved using the index of the pointed object. On load, pointers are filled with indices and need to be fixed to point to the real object. Must be overridden if the chunk saves any pointer.

Reimplemented in VEHSChunkHandler, ROADChunkHandler, STNNChunkHandler, PLYRChunkHandler, STNSChunkHandler, LGRSChunkHandler, CITYChunkHandler, BKORChunkHandler, INDYChunkHandler, ORDLChunkHandler, CHKPChunkHandler, ORDRChunkHandler, CAPYChunkHandler, ERNWChunkHandler, DEPTChunkHandler, and OBJSChunkHandler.

Definition at line 481 of file saveload.h.

◆ Load()

virtual void ChunkHandler::Load ( ) const

pure virtual

Load the chunk.

Must be overridden.

Implemented in VEHSChunkHandler, ROADChunkHandler, STNNChunkHandler, PLYRChunkHandler, STNSChunkHandler, GLOGChunkHandler, ITBLChunkHandler, MAP8ChunkHandler, LGRSChunkHandler, IBLDChunkHandler, MAP7ChunkHandler, LGRJChunkHandler, CITYChunkHandler, BKORChunkHandler, LGRPChunkHandler, MAPEChunkHandler, INDYChunkHandler, MAP5ChunkHandler, ORDLChunkHandler, M3HIChunkHandler, EIDSChunkHandler, PATSChunkHandler, CHKPChunkHandler, M3LOChunkHandler, VIEWChunkHandler, ENGSChunkHandler, GSTRChunkHandler, MAP2ChunkHandler, CAPAChunkHandler, OPTSChunkHandler, DATEChunkHandler, ORDRChunkHandler, MAPOChunkHandler, NAMEChunkHandler, RAILChunkHandler, CMPUChunkHandler, NGRFChunkHandler, CAPYChunkHandler, MAPHChunkHandler, STPAChunkHandler, ENGNChunkHandler, AIPLChunkHandler, LEATChunkHandler, ECMYChunkHandler, MAPTChunkHandler, CMDLChunkHandler, GSDTChunkHandler, STPEChunkHandler, CHTSChunkHandler, GRPSChunkHandler, OBJSChunkHandler, SIGNChunkHandler, DEPTChunkHandler, SUBSChunkHandler, MAPSChunkHandler, LEAEChunkHandler, ERNWChunkHandler, GOALChunkHandler, CAPRChunkHandler, ANITChunkHandler, SRNDChunkHandler, PSACChunkHandler, PRICChunkHandler, WaterRegionChunkHandler, and NewGRFMappingChunkHandler.

◆ LoadCheck()

void ChunkHandler::LoadCheck ( size_t len = 0 ) const

virtual

Load the chunk for game preview.

Default implementation just skips the data.

Parameters

len	Number of bytes to skip.

Reimplemented in PLYRChunkHandler, GLOGChunkHandler, PATSChunkHandler, DATEChunkHandler, NGRFChunkHandler, and MAPSChunkHandler.

Definition at line 1976 of file saveload.cpp.

References _sl, and SaveLoadParams::block_mode.

◆ Save()

virtual void ChunkHandler::Save ( ) const

inlinevirtual

Save the chunk.

Must be overridden, unless Chunk type is CH_READONLY.

Reimplemented in VEHSChunkHandler, ROADChunkHandler, STNNChunkHandler, PLYRChunkHandler, GLOGChunkHandler, MAP8ChunkHandler, ITBLChunkHandler, LGRSChunkHandler, MAP7ChunkHandler, IBLDChunkHandler, LGRJChunkHandler, MAPEChunkHandler, CITYChunkHandler, BKORChunkHandler, LGRPChunkHandler, MAP5ChunkHandler, M3HIChunkHandler, ORDLChunkHandler, PATSChunkHandler, INDYChunkHandler, M3LOChunkHandler, EIDSChunkHandler, GSTRChunkHandler, MAP2ChunkHandler, VIEWChunkHandler, AIPLChunkHandler, CAPAChunkHandler, MAPOChunkHandler, ORDRChunkHandler, DATEChunkHandler, MAPHChunkHandler, GSDTChunkHandler, RAILChunkHandler, CAPYChunkHandler, CMPUChunkHandler, STPAChunkHandler, ENGNChunkHandler, MAPTChunkHandler, NGRFChunkHandler, ECMYChunkHandler, LEATChunkHandler, CMDLChunkHandler, CHTSChunkHandler, STPEChunkHandler, PSACChunkHandler, SIGNChunkHandler, DEPTChunkHandler, GRPSChunkHandler, OBJSChunkHandler, SUBSChunkHandler, LEAEChunkHandler, MAPSChunkHandler, ERNWChunkHandler, GOALChunkHandler, ANITChunkHandler, SRNDChunkHandler, and NewGRFMappingChunkHandler.
