Detailed Description

Helper class for using binary search operatin lookup strategy in the server skeletons.

This class declares pure virtual method called 'lookup ()' which will be generated by the GPERF program. This method is used by 'bind ()' and 'find ()' methods. Subclasses will define the lookup method.

Member Function Documentation

int TAO_Binary_Search_OpTable::bind (  const char *  opname,
const TAO::Operation_Skeletons  skel_ptr
)  [virtual]
 

Associate the skeleton skel_ptr with an operation named opname. Returns -1 on failure, 0 on success, 1 on duplicate.

Implements TAO_Operation_Table.

int TAO_Binary_Search_OpTable::find (  const char *  opname,
TAO_Collocated_Skeleton &  skelfunc,
TAO::Collocation_Strategy  s,
const unsigned int  length = 0
)  [virtual]
 

Uses opname to look up the collocated skeleton function and pass it back in skelfunc. Returns non-negative integer on success, or -1 on failure.

Implements TAO_Operation_Table.
