CodeLocation (proguard-core 9.3.3-wcpe-3 API)

java.lang.Object
- proguard.analysis.datastructure.Location
- - proguard.analysis.datastructure.CodeLocation

所有已实现的接口:

java.lang.Comparable<Location>
```
public class CodeLocation
extends Location
```
Represents a unique location in the bytecode. It comprises the Clazz and Member where it is contained, the offset therein and the corresponding line number in the source file (Location.UNKNOWN_LINE if it is unknown). Consider the following pseudo-bytecode example which contains code location comments:
```
 public class Test
 {
     // class "Test", member "field", line 3, offset 0
     public String field;

     public String toString()
     {
         // class "Test", member "toString", line 6, offset 0
         aload_0
         // class "Test", member "toString", line 6, offset 1
         getfield #1 &lt;Test.field : Ljava/lang/String;&gt;
         // class "Test", member "toString", line 6, offset 4
         areturn
     }
 }

 
```
- Inside methods: Like each location, instructions inside methods have a line number. But as there may be several expressions on the same line, to correctly identify each instruction we also need their bytecode offset. E.g. the getfield instruction inside toString() has the offset 1.
- Fields: In this case Test#field. A field location has a line number (3 in this example) but no offset, as this concept is only applicable to methods.
