Method Summary

All Methods Instance Methods Abstract Methods
Modifier and Type	Method	Description
`void`	`discoverTypes(String className, byte[] originalBytes)`	Discovers types prior to enhancement.
`byte[]`	`enhance(String className, byte[] originalBytes)`	Performs the enhancement.

- Method Detail
  - enhance
```
byte[] enhance(String className,
               byte[] originalBytes)
        throws EnhancementException
```
    Performs the enhancement. It is possible to invoke this method concurrently, but when doing so make sure no two enhancement tasks are invoked on the same class in parallel: the Enhancer implementations are not required to guard against this.
    
    Parameters:
    
    className - The name of the class whose bytecode is being enhanced.
    
    originalBytes - The class's original (pre-enhancement) byte code
    
    Returns:
    
    The enhanced bytecode. If the original bytes are not enhanced, null is returned.
    
    Throws:
    
    EnhancementException - Indicates a problem performing the enhancement
  - discoverTypes
```
void discoverTypes(String className,
                   byte[] originalBytes)
            throws EnhancementException
```
    Discovers types prior to enhancement. It is possible to invoke this method concurrently.
    
    Parameters:
    
    className - The name of the class whose bytecode is being analyzed for type discovery.
    
    originalBytes - The class's original (pre-enhancement) byte code
    
    Throws:
    
    EnhancementException - Indicates a problem during type discovery
