org.ssssssss.script.compile中Label的使用

参数类型为Label的org.ssssssss.script.compile中的方法

修饰符和类型	方法	说明
MagicScriptCompiler	MagicScriptCompiler.jump(int opcode, Label label)	跳转
MagicScriptCompiler	MagicScriptCompiler.label(Label label)
MagicScriptCompiler	MagicScriptCompiler.markLabel(Label start, Label end)	标识continue和break位置
MagicScriptCompiler	MagicScriptCompiler.tryCatch(Label start, Label end, Label handle, Class<?> target)	设定tryCatch跳转 如果在Label start到Label end代码范围内捕获到type异常，则跳转到Label handler type为null则表示finally，只要抛异常就跳转到handler
