Class Overview
Property editor for java.util.Date,
supporting a custom java.text.DateFormat.
This is not meant to be used as system PropertyEditor but rather as locale-specific date editor within custom controller code, parsing user-entered number strings into Date properties of beans and rendering them in the UI form.
In web MVC code, this editor will typically be registered with
binder.registerCustomEditor calls in a custom
initBinder method.

Public Constructors
public CustomDateEditor (DateFormat dateFormat, boolean allowEmpty)
Create a new CustomDateEditor instance, using the given DateFormat for parsing and rendering.
The "allowEmpty" parameter states if an empty String should be allowed for parsing, i.e. get interpreted as null value. Otherwise, an IllegalArgumentException gets thrown in that case.
Parameters
| dateFormat | DateFormat to use for parsing and rendering |
|---|---|
| allowEmpty | if empty strings should be allowed |
public CustomDateEditor (DateFormat dateFormat, boolean allowEmpty, int exactDateLength)
Create a new CustomDateEditor instance, using the given DateFormat for parsing and rendering.
The "allowEmpty" parameter states if an empty String should be allowed for parsing, i.e. get interpreted as null value. Otherwise, an IllegalArgumentException gets thrown in that case.
The "exactDateLength" parameter states that IllegalArgumentException gets
thrown if the String does not exactly match the length specified. This is useful
because SimpleDateFormat does not enforce strict parsing of the year part,
not even with setLenient(false). Without an "exactDateLength"
specified, the "01/01/05" would get parsed to "01/01/0005". However, even
with an "exactDateLength" specified, prepended zeros in the day or month
part may still allow for a shorter year part, so consider this as just
one more assertion that gets you closer to the intended date format.
Parameters
| dateFormat | DateFormat to use for parsing and rendering |
|---|---|
| allowEmpty | if empty strings should be allowed |
| exactDateLength | the exact expected length of the date String |
Public Methods
public void setAsText (String text)
Parse the Date from the given text, using the specified DateFormat.
Throws
| IllegalArgumentException |
