public BasicInterpreter()
BasicInterpreter for the latest ASM API version. Subclasses must
not use this constructor. Instead, they must use the BasicInterpreter(int)
version.protected BasicInterpreter(int api)
BasicInterpreter.api - the ASM API version supported by this interpreter. Must be one of the ASMx values in Opcodes.public BasicValue newValue(Type type)
InterpreterCalled for method parameters (including this), exception handler variable and
with null type for variables reserved by long and double types.
An interpreter may choose to implement one or more of Interpreter.newReturnTypeValue(Type), Interpreter.newParameterValue(boolean, int,
Type), Interpreter.newEmptyValue(int), Interpreter.newExceptionValue(TryCatchBlockNode, Frame, Type) to distinguish different types
of new value.
