java - How do I remove the body of a method or constructor with javassist? -


i need remove body of constructors , methods w/ void return type using javassist library. following works.

ctclass.getconstructors()[0].setbody("int = 0");

but doesn't

ctclass.getconstructors()[0].setbody("");

instead exception

compile error: syntax near ""

when try

ctclass.getconstructors()[0].setbody(null);

i get

compiler error: no such constructor

i same error when trying empty method w/ void return type. looking through google , documentation, can't figure out how empty out body without inserting kind of code , don't want add arbitrary code no reason.

javassist replaces method body valid block body of method. non-statement not valid block. can instead set { } method body block. alternatively, make implicit return; statement explicit.

for constructor, required invoke super costructor or auxiliary constructor first. empty block not valid.

utf 8 - split utf-8 string into bytes in python -

i trying split utf-8 string bytes in python 3. problem is, when use bytearray, byte, encode etc functions array size of element 14 bytes, not 1 byte expected. need split text file sequence of bytes , send them byte after byte using sockets. tried this: infile = open (file, "r") str = infile.read() byte_str = bytes(str, 'utf-8') print("size of byte_str",sys.getsizeof(byte_str[0])) print gives me 14, need 1... suggestion? quoting official documentation : sys.getsizeof(object[, default]) return size of object in bytes. object can type of object. built-in objects return correct results, not have hold true third-party extensions implementation specific. only memory consumption directly attributed object accounted for, not memory consumption of objects refers to. if given, default returned if object not provide means retrieve size. otherwise typeerror raised. getsizeof() calls object’s __sizeof__ method , adds ...
