object TACNaive
Converts the bytecode of a method into a three address representation using a very naive approach where each each operand stack value is stored in a local variable based on the position of the value on the stack and where each local variable is stored in a local variable named based on the register's index (In general, you should use the three-address code create using TACAI).
The converted method has an isomorophic CFG when compared to the original method, but may contain more instructions due to the way how the stack manipulation instructions are transformed. In general - unless JSR/RET instructions are found - no CFG is created and used. This approach relies on the invariant that the stack has to have the same layout on all paths. This makes the transformation very fast, but also makes it impossible to trivially compute the type information.

Converts the plain bytecode of a method into a quadruples based three address representation.
Converts the plain bytecode of a method into a quadruples based three address representation. Compared to the previous method, no data- and control-flow information is used and a very general transformation mechanism is used to do the transformation. Therefore the representation is very verbose. However, both leverage the same AST nodes.
- method
A method with a body. I.e., a non-native, non-abstract method.
- classHierarchy
The class hierarchy of the project defining the given method. If the class hierarchy is not available, you can use:
ClassHierarchy.PreInitializedClassHierarchy.- returns
The array with the generated statements.
