Class NameTransformer

java.lang.Object
  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.

Method Detail

simpleTransformer

public static NameTransformer simpleTransformer(String prefix,
                                                String suffix)

Factory method for constructing a simple transformer based on prefix and/or suffix.

chainedTransformer

public 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.

transform

public abstract String transform(String name)

Method called when (forward) transformation is needed.

reverse

public 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.
