Method Detail

parseTextEntry

NakedObject parseTextEntry(NakedObject original,
                           java.lang.String text)

Parses a text entry made by a user and sets the domain object's value.

Equivalent to Parser#parseTextEntry(Object, String), though may be implemented through some other mechanism.

Throws:

InvalidEntryException

TextEntryParseException

parseableTitle

java.lang.String parseableTitle(NakedObject obj)

A title for the object that is valid but which may be easier to edit than the title provided by a TitleFacet.

The idea here is that the viewer can display a parseable title for an existing object when, for example, the user initially clicks in the field. So, a date might be rendered via a TitleFacet as May 2, 2007, but its parseable form might be 20070502.
