Method Detail

getText

public java.lang.String getText(TemporalField field,
                                long value,
                                TextStyle style,
                                java.util.Locale locale)

Description copied from class: DateTimeTextProvider

Gets the text for the specified field, locale and style for the purpose of printing.

The text associated with the value is returned. The null return value should be used if there is no applicable text, or if the text would be a numeric representation of the value.

Specified by:

getText in class DateTimeTextProvider

Parameters:

field - the field to get text for, not null

value - the field value to get text for, not null

style - the style to get text for, not null

locale - the locale to get text for, not null

Returns:

the text for the field value, null if no text found

getTextIterator

public java.util.Iterator<java.util.Map.Entry<java.lang.String,java.lang.Long>> getTextIterator(TemporalField field,
                                                                                                      TextStyle style,
                                                                                                      java.util.Locale locale)

Description copied from class: DateTimeTextProvider

Gets an iterator of text to field for the specified field, locale and style for the purpose of parsing.

The iterator must be returned in order from the longest text to the shortest.

The null return value should be used if there is no applicable parsable text, or if the text would be a numeric representation of the value. Text can only be parsed if all the values for that field-style-locale combination are unique.

Specified by:

getTextIterator in class DateTimeTextProvider

Parameters:

field - the field to get text for, not null

style - the style to get text for, null for all parsable text

locale - the locale to get text for, not null

Returns:

the iterator of text to field pairs, in order from longest text to shortest text, null if the field or style is not parsable
