Examples of CoercionTuple

org.apache.tapestry.ioc.services.CoercionTuple
An immutable object that represents a mapping from one type to another. This is also the contribution type when buildign the TypeCoercer service. Wraps a {@link Coercion} object thatperforms the work with additional properties that describe the input and output types of the coercion, needed when searching for an appropriate coercion (or combination of coercions). @param < S> source (input) type @param < T> target (output) type
