  - compose
```
default CharMapper compose(CharMapper before)
```
    Returns a composed operator that first applies the before operator to its input, and then applies this operator to the result. If evaluation of either operator throws an exception, it is relayed to the caller of the composed operator.
    
    Parameters:
    
    before - the operator to apply before this operator is applied
    
    Returns:
    
    a composed operator that first applies the before operator and then applies this operator
    
    Throws:
    
    java.lang.NullPointerException - if before is null
