Interface StringValueReader<T>

Type Parameters:

T - the supported Java type produced as a result of string value conversion.

public interface StringValueReader<T>

Read a string value and convert to a Java type.

A StringValueReaderProvider is responsible for providing an instance of this interface.

If annotated with ValidateDefaultValue(true) or if the annotation is absent then the reader will be used to eagerly convert a default value (if any) by calling the fromString(java.lang.String) transformation method, perhaps at initialization, before any value – default or otherwise – is actually required. This enables the early reporting of errors for default values. If annotated with ValidateDefaultValue(false) then the reader will not be used to eagerly convert a default value (if any).
