Method Summary
All Methods Static Methods Instance Methods Abstract Methods Concrete Methods Modifier and Type Method 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 callingtransform(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.
