Macro IloFloatArray

IloFloatArray is the array class of the basic floating-point class for a model. It is a handle class. The implementation class for IloFloatArray is the undocumented class IloFloatArrayI.

Instances of IloFloatArray are extensible. (They differ from instances of IlcFloatArray in this respect. IlcFloatArray is documented in the ILOG Solver Reference Manual.)

For each basic type, Concert Technology defines a corresponding array class. That array class is a handle class. In other words, an object of that class contains a pointer to another object allocated on the Concert Technology heap associated with a model. Exploiting handles in this way greatly simplifies the programming interface since the handle can then be an automatic object: as a developer using handles, you do not have to worry about memory allocation.

As handles, these objects should be passed by value, and they should be created as automatic objects, where “automatic” has the usual C++ meaning.

Member functions of a handle class correspond to member functions of the same name in the implementation class.

Assert and NDEBUG

Most member functions of the class IloFloatArray are inline functions that contain an assert statement. This statement checks that the handle pointer is non-null. These statements can be suppressed by the macro NDEBUG. This option usually reduces execution time. The price you pay for this choice is that attempts to access through null pointers are not trapped and usually result in memory faults.
