public abstract class DecodedInstruction
extends java.lang.Object
```
A decoded Dalvik instruction. This consists of a format codec, a numeric opcode, an optional index type, and any additional arguments of the instruction. The additional arguments (if any) are represented as uninterpreted data.
Note: The names of the arguments are not meant to match the names given in the Dalvik instruction format specification, specification which just names fields (somewhat) arbitrarily alphabetically from A. In this class, non-register fields are given descriptive names and register fields are consistently named alphabetically.
