◆ SCIP_DECL_READERFREE()
SCIP_DECL_READERFREE | ( | ReaderTSP::scip_free | ) |
destructor of file reader to free user data (called when SCIP is exiting)

◆ SCIP_DECL_READERREAD()
SCIP_DECL_READERREAD | ( | ReaderTSP::scip_read | ) |
problem reading method of reader
possible return values for *result:
- SCIP_SUCCESS : the reader read the file correctly and created an appropritate problem
- SCIP_DIDNOTRUN : the reader is not responsible for given input file
If the reader detected an error in the input file, it should return with RETCODE SCIP_READERR or SCIP_NOFILE.

◆ SCIP_DECL_READERWRITE()
SCIP_DECL_READERWRITE | ( | ReaderTSP::scip_write | ) |
problem writing method of reader; NOTE: if the parameter "genericnames" is TRUE, then SCIP already set all variable and constraint names to generic names; therefore, this method should always use SCIPvarGetName() and SCIPconsGetName();
possible return values for *result:
- SCIP_SUCCESS : the reader read the file correctly and created an appropritate problem
- SCIP_DIDNOTRUN : the reader is not responsible for given input file
If the reader detected an error in the writing to the file stream, it should return with RETCODE SCIP_WRITEERROR.
