object TACAI
Factory to convert the bytecode of a method into a three address representation using the results of a(n) (local) abstract interpretation of the method.
The generated representation is completely parameterized over the domains that were used to perform the abstract interpretation. The only requirement is that the Def/Use information is recorded while performing the abstract interpretation (see org.opalj.ai.domain.RecordDefUse).
The generated representation is necessarily in static single assignment form: each variable is assigned exactly once, and every variable is defined before it is used. However, no PHI instructions are inserted; instead - in case of a use - we simply directly refer to all def sites.

Converts the bytecode of a method into a three address representation using the result of an abstract interpretation.
Converts the bytecode of a method into a three address representation using the result of an abstract interpretation.
- method
A method with a body. I.e., a non-native, non-abstract method.
- aiResult
The result of the abstract interpretation of the respective method.
- optimizations
The transformations that should be executed (NoOptimizations is always possible).
- returns
The array with the generated statements.

Returns a map which maps an ai-based value origin for a parameter to the tac value origin; to lookup the tac based origin, the ai-based origin aiVO has to be negated and 1 has to be subtracted.
