SCIP_DECL_READERFREE

(

ReaderTSP::scip_free

)

destructor of file reader to free user data (called when SCIP is exiting)

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

(

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.
