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

org.objectweb.asm.MethodVisitor.visitLocalVariable()
Visits a local variable declaration. @param name the name of a local variable. @param desc the type descriptor of this local variable. @param signature the type signature of this local variable. May benull if the local variable type does not use generic types. @param start the first instruction corresponding to the scope of thislocal variable (inclusive). @param end the last instruction corresponding to the scope of this localvariable (exclusive). @param index the local variable's index. @throws IllegalArgumentException if one of the labels has not alreadybeen visited by this visitor (by the {@link #visitLabel visitLabel} method).
