Examples of org.objectweb.asm.MethodVisitor.visitLineNumber()

org.objectweb.asm.MethodVisitor.visitLineNumber()
Visits a line number declaration. @param line a line number. This number refers to the source file fromwhich the class was compiled. @param start the first instruction corresponding to this line number. @throws IllegalArgumentException if start has not already beenvisited by this visitor (by the {@link #visitLabel visitLabel}method).
