Compatibility with Java CPLEX

Describes the relationship of the ilog.concert and ilog.cplex packages with their equivalent packages in IBM ILOG CPLEX.

The ilog.concert and ilog.cplex packages are designed to be compatible with the equivalent packages in IBM ILOG CPLEX.. This means that they offer the same API (slightly extended for OPL), although the implementation is quite different. The benefit is that you can reuse your existing JConcert/Java CPLEX modeling code and combine it with OPL models.

Because OPL can produce full Concert models and offers a backward compatible API, you benefit from a smooth migration path to OPL without losing your previous work.

Note:

  1. The CPLEX Java API related to IloLPMatrix, which allows direct manipulation of the CPLEX matrix in Java, is not available in the OPL implementation.

  2. Serialization is not supported for JConcert modeling classes.

  3. CPLEX callbacks are supported with parallel search in Java interfaces.
