java.lang.Object
org.babyfish.jimmer.impl.asm.Label
public class Label extends Object
A position in the bytecode of a method. Labels are used for jump, goto, and switch instructions, and for try catch blocks. A label designates the instruction that is just after. Note however that there can be other elements between a label and the instruction it designates (such as other labels, stack map frames, line numbers, etc.).
