- com.fasterxml.jackson.databind.util.NameTransformer

Direct Known Subclasses:

NameTransformer.Chained, NameTransformer.NopTransformer
```
public abstract class NameTransformer
extends Object
```
Helper class used to encapsulate details of name mangling, transforming of names using different strategies (prefixes, suffixes). Default implementation is "no-operation" (aka identity transformation).

Methods
Modifier and Type	Method and Description
`static NameTransformer`	`chainedTransformer(NameTransformer t1, NameTransformer t2)` Method that constructs transformer that applies given transformers as a sequence; essentially combines separate transform operations into one logical transformation.
`abstract String`	`reverse(String transformed)` Method called when reversal of transformation is needed; should return null if this is not possible, that is, given name cannot have been result of calling `transform(java.lang.String)` of this object.
`static NameTransformer`	`simpleTransformer(String prefix, String suffix)` Factory method for constructing a simple transformer based on prefix and/or suffix.
`abstract String`	`transform(String name)` Method called when (forward) transformation is needed.
