Class CEnvironment

java.lang.Object
com.pnfsoftware.jeb.core.units.code.asm.decompiler.ast.simulator.CEnvironment
public class CEnvironment extends Object
Simulation environment. Serves as a proxy to access outside method world. In particular it provides:
  • concrete values for parameters, routine calls, global variables
  • access to the underlying native unit
The environment might be modified by a simulation, namely by writing into global variables or into memory. The stateful information should be cleared before an environment can be re-used for a simulation (see clearState()).
