Context (long m_ctx) | |
The main interaction with Z3 happens via the Context. For applications that spawn an unbounded number of contexts, the proper use is within a try-with-resources scope so that the Context object gets garbage collected in a predictable way. Contexts maintain all data-structures related to terms and formulas that are created relative to them.
