Method Summary

All Methods Instance Methods Concrete Methods
Modifier and Type	Method and Description
`void`	`endSubroutine(Clazz clazz, Method method, TracedVariables variablesAfter, TracedStack stackAfter, int subroutineStart, int subroutineEnd)` The evaluation and generalization of the subroutine is done, the partial evaluator moves on.
`void`	`evaluationResults(Clazz clazz, Method method, CodeAttribute codeAttribute, PartialEvaluator evaluator)` Partial evaluator is done evaluating the code attribute.
`void`	`generalizeInstructionBlock(Clazz clazz, Method method, int instructionOffset, Instruction instruction, TracedVariables variablesBefore, TracedStack stackBefore, int evaluationCount)` The instruction has been seen a certain number of times and the evaluator deems it time to start generalizing the instruction.
`java.lang.String`	`getJson()`
`void`	`printState()`
`void`	`registerAlternativeBranch(Clazz clazz, Method method, int fromInstructionOffset, Instruction fromInstruction, TracedVariables variablesAfter, TracedStack stackAfter, int branchIndex, int branchTargetCount, int offset)` The evaluator detects multiple branches need to be evaluated.
`void`	`registerException(Clazz clazz, Method method, CodeAttribute codeAttribute, PartialEvaluator evaluator, java.lang.Throwable cause)` An exception has been thrown while evaluating the current code attribute.
`void`	`registerExceptionHandler(Clazz clazz, Method method, int startPC, int endPC, ExceptionInfo info)` Partial evaluator starts evaluating a specific exception handler.
`void`	`registerSubroutineReturn(Clazz clazz, Method method, int returnOffset, TracedVariables returnVariables, TracedStack returnStack)` The current instruction was RET and the partial evaluator pushes the return address to the branch stack of the calling partial evaluator.
`void`	`skipInstructionBlock(Clazz clazz, Method method, int instructionOffset, Instruction instruction, TracedVariables variablesBefore, TracedStack stackBefore, int evaluationCount)` The instruction within this instruction block has been seen with the those variables and this stack, and thus it is not needed to evaluate this block any further.
`void`	`startCodeAttribute(Clazz clazz, Method method, CodeAttribute codeAttribute, Variables parameters)` The partial evaluator starts with the evaluation of a code block.
`void`	`startInstructionBlock(Clazz clazz, Method method, CodeAttribute codeAttribute, TracedVariables startVariables, TracedStack startStack, int startOffset)` Partial evaluator starts evaluating an instruction block, specified by an instruction range within the code attribute and the variables and stack it would start with.
`void`	`startInstructionEvaluation(Clazz clazz, Method method, int instructionOffset, Instruction instruction, TracedVariables variablesBefore, TracedStack stackBefore, int evaluationCount)` The partial evaluator will forward the evaluation of the instruction.
`void`	`startSubroutine(Clazz clazz, Method method, TracedVariables startVariables, TracedStack startStack, int subroutineStart, int subroutineEnd)` The current instruction was JSR or JSR_W and the partial evaluator starts with the evaluation of the subroutine.
`void`	`writeState(java.lang.String fileName)`
