All Methods Static Methods Instance Methods Abstract Methods
Modifier and Type	Method	Description
`static KeyValueProcessor`	`chain(KeyValueProcessor... processors)`	Process a chain of `KeyValueProcessor` processors in the order they are added.

- Method Detail
  - process
```
Optional<KeyValueProcessor.Value> process(String key,
                                          KeyValueProcessor.Value value)
```
    For a given key/value pair, return the processed value as an Optional.
    
    Parameters:
    
    key - the key
    
    value - the KeyValueProcessor.Value to process
    
    Returns:
    
    an Optional with the value after processing, which if empty, means there was no value as a result.
  - chain
```
static KeyValueProcessor chain(KeyValueProcessor... processors)
```
    Process a chain of KeyValueProcessor processors in the order they are added.
    
    Parameters:
    
    processors - a list of KeyValueProcessor.
    
    Returns:
    
    a KeyValueProcessor which represents a chain all the passed KeyValueProcessor
