java.beans.PropertyEditorSupport

org.jasig.portlet.blackboardvcportlet.mvc.sessionmngr.CustomDateMidnightEditor

All Implemented Interfaces:

PropertyEditor

public class CustomDateMidnightEditor
extends PropertyEditorSupport

Property editor for org.joda.time.DateMidnight, supporting a custom org.joda.time.format.DateTimeFormatter. This class is modeled on Spring's CustomDateEditor.

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.

Constructor Detail

CustomDateMidnightEditor

public CustomDateMidnightEditor(org.joda.time.format.DateTimeFormatter 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

CustomDateMidnightEditor

public CustomDateMidnightEditor(org.joda.time.format.DateTimeFormatter 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".

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
