Class NameTransformer

java.lang.Object
  extended by com.fasterxml.jackson.databind.util.NameTransformer
Direct Known Subclasses:
NameTransformer.Chained

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).


Nested Class Summary
static class NameTransformer.Chained
           
 
Field Summary
static NameTransformer NOP
          Singleton "no-operation" transformer which simply returns given name as is.
 
Constructor Summary
protected NameTransformer()
           
 
Method Summary
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 can not 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.

transform

public abstract String transform(String name)
Method called when (forward) transformation is needed.
