Method Detail

getFieldTypes

Set<Class<?>> getFieldTypes()

The types of fields that may be annotated with the <A> annotation.

getPrinter

Printer<?> getPrinter(A annotation,
                      Class<?> fieldType)

Get the Printer to print the value of a field of fieldType annotated with annotation. If the type <T> the printer accepts is not assignable to fieldType, a coersion from fieldType to <T> will be attempted before the Printer is invoked.

Parameters:

annotation - the annotation instance

fieldType - the type of field that was annotated

Returns:

the printer

getParser

Parser<?> getParser(A annotation,
                    Class<?> fieldType)

Get the Parser to parse a submitted value for a field of fieldType annotated with annotation. If the object the parser returns is not assignable to fieldType, a coersion to fieldType will be attempted before the field is set.

Parameters:

annotation - the annotation instance

fieldType - the type of field that was annotated

Returns:

the parser
