public int getLineNumber(int pos)
pos
- the position of the bytecode (>= 0). an index into the code
array.
public void setSuperclass(java.lang.String superclass) throws BadBytecode
This method modifies a call to super()
, which should be
at the head of a constructor body, so that a constructor in a different
super class is called. This method does not change actual parameters.
Hence the new super class must have a constructor with the same signature
as the original one.
This method should be called when the super class of the class declaring this method is changed.
This method does not perform anything unless this MethodInfo
represents a constructor.
superclass
- the new super class
