Class BytecodeAttribute.Unknown

java.lang.Object

jasm.lang.BytecodeAttribute.Unknown

All Implemented Interfaces:

BytecodeAttribute

Enclosing interface:

BytecodeAttribute

public static class BytecodeAttribute.Unknown
extends Object
implements BytecodeAttribute

Class for representing unknown attributes. This class does not write the same attribute back out but, instead, boxes inside a specia "Unknown" attribute. The reason for this is that, if the attribute contains e.g. constant pool items, then their indices may be incorrect.
