MethodInfo

public MethodInfo(ConstPool cp,
          String methodname,
          String desc)

Constructs a method_info structure. The initial value of access_flags is zero.

Parameters:

cp - a constant pool table

methodname - method name

desc - method descriptor

MethodInfo

public MethodInfo(ConstPool cp,
          String methodname,
          MethodInfo src,
          Map<?,?> classnameMap)

Constructs a copy of method_info structure. Class names appearing in the source method_info are renamed according to classnameMap.

Note: only Code and Exceptions attributes are copied from the source. The other attributes are ignored.

Parameters:

cp - a constant pool table

methodname - a method name

src - a source method_info

classnameMap - specifies pairs of replaced and substituted name.
