Method Summary | |
---|---|
Value | binaryOperation(AbstractInsnNode insn, Value value1, Value value2)
Interprets a bytecode instruction with two arguments. |
Value | copyOperation(AbstractInsnNode insn, Value value)
Interprets a bytecode instruction that moves a value on the stack or to
or from local variables. |
Value | merge(Value v, Value w)
Merges two values. |
Value | naryOperation(AbstractInsnNode insn, List values)
Interprets a bytecode instruction with a variable number of arguments.
|
Value | newOperation(AbstractInsnNode insn)
Interprets a bytecode instruction without arguments. |
Value | newValue(Type type)
Creates a new value that represents the given type.
|
Value | ternaryOperation(AbstractInsnNode insn, Value value1, Value value2, Value value3)
Interprets a bytecode instruction with three arguments. |
Value | unaryOperation(AbstractInsnNode insn, Value value)
Interprets a bytecode instruction with a single argument. |
Parameters: insn the bytecode instruction to be interpreted. value1 the first argument of the instruction to be interpreted. value2 the second argument of the instruction to be interpreted.
Returns: the result of the interpretation of the given instruction.
Throws: AnalyzerException if an error occured during the interpretation.
Parameters: insn the bytecode instruction to be interpreted. value the value that must be moved by the instruction.
Returns: the result of the interpretation of the given instruction. The returned value must be equal to the given value.
Throws: AnalyzerException if an error occured during the interpretation.
Parameters: v a value. w another value.
Returns: the merged value. If the merged value is equal to v, this method must return v.
Parameters: insn the bytecode instruction to be interpreted. values the arguments of the instruction to be interpreted.
Returns: the result of the interpretation of the given instruction.
Throws: AnalyzerException if an error occured during the interpretation.
Parameters: insn the bytecode instruction to be interpreted.
Returns: the result of the interpretation of the given instruction.
Throws: AnalyzerException if an error occured during the interpretation.

Parameters: type a primitive or reference type, or null to represent an uninitialized value.
Returns: a value that represents the given type. The size of the returned value must be equal to the size of the given type.
Parameters: insn the bytecode instruction to be interpreted. value1 the first argument of the instruction to be interpreted. value2 the second argument of the instruction to be interpreted. value3 the third argument of the instruction to be interpreted.
Returns: the result of the interpretation of the given instruction.
