java.lang.Object
- proguard.classfile.Signature

所有已实现的接口:

java.lang.Comparable<Signature>

直接已知子类:

ClassSignature, FieldSignature, MethodSignature
```
public abstract class Signature
extends java.lang.Object
implements java.lang.Comparable<Signature>
```
A signature currently can be a Method- or a FieldSignature. This class can be used to create the correct one from a ProguardCORE member object (which can also be a method or a field).

public abstract boolean isIncomplete()

  - of
```
public static Signature of(Clazz clazz,
                           Member member)
```
    Convenience factory that takes any Member and generates the appropriate signature, i.e. MethodSignatures for Methods and FieldSignatures for Fields. If the member is null, a ClassSignature is generated.
    Note that if cacheEnabled is set to true, the generation process is delegated to computeIfAbsent(Clazz, Member) to make use of caching features.
    
    参数:
    
    clazz - The class containing the member
    
    member - The target member
    
    返回:
    
    The corresponding Signature object
  - computeIfAbsent
```
public static Signature computeIfAbsent(Clazz clazz,
                                        Member member)
```
    This factory uses the caching features provided by MethodSignature.computeIfAbsent(Clazz, Method), FieldSignature.computeIfAbsent(Clazz, Field) and ClassSignature.computeIfAbsent(Clazz). Only one signature is created for each distinct Method, Field or Clazz. If the same signature is requested several times, the previously created object will be returned.
    
    参数:
    
    clazz - The class containing the member
    
    member - The target member
    
    返回:
    
    The corresponding Signature object
  - clearCache
```
public static void clearCache()
```
    Clear the signature caches of all Signature subclasses.
  - setCacheEnabled
```
public static void setCacheEnabled(boolean cacheEnabled)
```
    Enable or disable automatic caching in of(Clazz, Member). Existing caches are purged once caching has been disabled.
  - getFqn

public java.lang.String getFqn()
```
  - getPrettyFqn
```
public java.lang.String getPrettyFqn()
