Detailed Description
Defines basic File Access Module, under the control of IGESReaderTool for Reading and IGESWriter for Writing : Specific actions concern : Read and Write Own Parameters of an IGESEntity. The common parts (Directory Entry, Lists of Associativities and Properties) are processed by IGESReaderTool & IGESWriter.
Each sub-class of ReadWriteModule is used in conjunction with a sub-class of Protocol from IGESData and processes several types of IGESEntity (typically, them of a package) : The Protocol gives a unique positive integer Case Number for each type of IGESEntity it recognizes, the corresponding ReadWriteModule processes an Entity by using the Case Number to known what is to do On Reading, the general service NewVoid is used to create an IGES Entity the first time
Warning : Works with an IGESReaderData which stores "DE parts" of Items
Member Function Documentation
◆ CaseIGES()
|
pure virtual |
Defines Case Numbers corresponding to the Entity Types taken into account by a sub-class of ReadWriteModule (hence, each sub-class of ReadWriteModule has to redefine this method) Called by CaseNum. Its result will then be used to call Read, etc ...
Implemented in IGESSolid_ReadWriteModule, IGESGraph_ReadWriteModule, IGESGeom_ReadWriteModule, IGESDraw_ReadWriteModule, IGESDimen_ReadWriteModule, IGESDefs_ReadWriteModule, IGESBasic_ReadWriteModule, and IGESAppli_ReadWriteModule.
◆ CaseNum()
|
overridevirtual |
Translates the Type of record <num> in <data> to a positive Case Number, or 0 if failed. Works with IGESReaderData which provides Type & Form Numbers, and calls CaseIGES (see below)
Implements Interface_ReaderModule.
◆ Read()
|
overridevirtual |
General Read Function. See IGESReaderTool for more info.
Implements Interface_ReaderModule.
◆ ReadOwnParams()
|
pure virtual |
Reads own parameters from file for an Entity; <PR> gives access to them, <IR> detains parameter types and values For each class, there must be a specific action provided Note that Properties and Associativities Lists are Read by specific methods (see below), they are called under control of reading process (only one call) according Stage recorded in ParamReader.
Implemented in IGESSolid_ReadWriteModule, IGESGraph_ReadWriteModule, IGESGeom_ReadWriteModule, IGESDraw_ReadWriteModule, IGESDimen_ReadWriteModule, IGESDefs_ReadWriteModule, IGESBasic_ReadWriteModule, and IGESAppli_ReadWriteModule.
◆ WriteOwnParams()
|
pure virtual |
Writes own parameters to IGESWriter; defined for each class (to be redefined for other IGES ReadWriteModules) Warning : Properties and Associativities are directly managed by WriteIGES, must not be sent by this method.
Implemented in IGESSolid_ReadWriteModule, IGESGraph_ReadWriteModule, IGESGeom_ReadWriteModule, IGESDraw_ReadWriteModule, IGESDimen_ReadWriteModule, IGESDefs_ReadWriteModule, IGESBasic_ReadWriteModule, and IGESAppli_ReadWriteModule.
