Method Detail

disassembleOne

public static String disassembleOne(ResolvedJavaMethod method,
                                    int bci)

disassemble

public String disassemble(ResolvedJavaMethod method)

Disassembles the bytecode of a given method in a javap-like format.

Returns:

null if method has no bytecode (e.g., it is native or abstract)
