public class DateFormatter
extends DateTimeFormatter

This class provides formatting of Date values in a FormattedText, restricting the edit and display to the time part. Supports a subset of time patterns defined in SimpleDateFormat for input.

See DateTimeFormatter for a full description of patterns, given that only patterns chars related to time are allowed.

Examples

• new DateFormatter("MM/dd/yyyy") - 8 jul 2006 will edit and display as "07/08/2006".
• new DateFormatter("dd/MM/yyyy, "dd MMM yyyy")- 8 jul 2006 will edit as "08/07/2006" and display as "08 Jul 2006".

DateFormatter

public DateFormatter(java.lang.String editPattern,
                     java.lang.String displayPattern)

Constructs a new instance with the given edit and display masks. Uses the default locale.

Parameters:

editPattern - edit mask

displayPattern - display mask

DateFormatter

public DateFormatter(java.lang.String editPattern,
                     java.lang.String displayPattern,
                     java.util.Locale loc)

Constructs a new instance with the given masks and locale.

loc - locale

Method Detail

getDefaultEditPattern

public java.lang.String getDefaultEditPattern(java.util.Locale loc)

Returns the default edit pattern for the given Locale.

A DateFormat object is instantiated with SHORT format for both the date part for the given locale. The corresponding pattern string is then retrieved by calling the toPattern.

Default patterns are stored in a cache with ISO3 language and country codes as key. So they are computed only once by locale.

Overrides:

getDefaultEditPattern in class DateTimeFormatter

Parameters:

loc - locale

Returns:

edit pattern for the locale

isValidCharPattern

protected void isValidCharPattern(char c)

Checks if a given char is valid for the edit pattern. This method overrides the parent method, restricting authorized chars to date patterns.

Overrides:

isValidCharPattern in class DateTimeFormatter

Parameters:

c - pattern char

Throws:

java.lang.IllegalArgumentException - if not valid
