Constructor Detail

ERXDateTimeFormatter

public ERXDateTimeFormatter(DateTimeFormatter formatter,
                            TemporalQuery<?> query)

Basic constructor.

Parameters:

formatter - the formatter to encapsulate

query - the method to extract correct date object from parsed results

ERXDateTimeFormatter

public ERXDateTimeFormatter(DateTimeFormatter formatter,
                            TemporalQuery<?> query,
                            String pattern)

Constructor that takes an additional string pattern. DateTimeFormatter objects unfortunately don't retain their pattern so you can't extract it from the object anymore. Some component like AjaxDatePicker though need that information so you can provide it with this constructor.

Parameters:

formatter - the formatter to encapsulate

query - the method to extract correct date object from parsed results

pattern - the pattern used by the formatter

Method Detail

format

public StringBuffer format(Object obj,
                           StringBuffer toAppendTo,
                           FieldPosition pos)

Specified by:

format in class Format

parseObject

public Object parseObject(String source,
                          ParsePosition pos)

Specified by:

parseObject in class Format

formatter

public DateTimeFormatter formatter()

The formatter to be used.

Returns:

the formatter

query

protected TemporalQuery<?> query()

The method reference that will create the correct object type from parsed result.

Returns:

query for the parsed temporal object

pattern

public String pattern()

The pattern used for the formatter. This information has to be given during construction of this object as DateTimeFormatter objects don't contain their original pattern as string.

Returns:

the pattern or null if none was provided

toString

public String toString()

Overrides:

toString in class Object
