Examples of org.apache.tapestry5.util.StringToEnumCoercion

org.apache.tapestry5.util.StringToEnumCoercion
A {@link org.apache.tapestry5.ioc.services.Coercion} for converting strings into an instance of a particularenumerated type. The {@link Enum#name() name} is used as the key to identify the enum instance, in a case-insensitivefashion.
Moved from tapestry-core to tapestry-ioc is release 5.3, but kept in same package for compatibility. @param < T> the type of enumeration
