Parameters:

transformer - Un Transformer

public Binding<M,V,C> setModelToView(org.apache.commons.collections15.Transformer<M,?> transformer)

setViewToModel

public Binding<M,V,C> setViewToModel(org.apache.commons.collections15.Transformer<?,M> transformer)

setAdapter

public Binding<M,V,C> setAdapter(Adapter adapter)

This is the most general way to set the strategy that adapts the values in the model to the values in the view. Only one adapter is supported, if this method is called twice, the first adapter will be discarded.
