- java.text.AttributedCharacterIterator.Attribute
- java.text.Format.Field
- java.text.DateFormat.Field
- java.text.Format.Field
All Implemented Interfaces:
Serializable
Enclosing class:
DateFormat
public static class DateFormat.Field
extends Format.Field
Defines constants that are used as attribute keys in theAttributedCharacterIterator
returned from DateFormat.formatToCharacterIterator
and as field identifiers in FieldPosition
.
The class also provides two methods to map between its constants and the corresponding Calendar constants.

Constructor Detail
* #### Field protected Field([String](../../java/lang/String.html "class in java.lang") name, int calendarField) Creates a `Field`. Parameters: `name` \- the name of the `Field` `calendarField` \- the `Calendar` constant this`Field` corresponds to; any value, even one outside the range of legal `Calendar` values may be used, but `-1` should be used for values that don't correspond to legal `Calendar` values
Method Detail
* #### ofCalendarField public static [DateFormat.Field](../../java/text/DateFormat.Field.html "class in java.text") ofCalendarField(int calendarField) Returns the `Field` constant that corresponds to the `Calendar` constant `calendarField`. If there is no direct mapping between the `Calendar` constant and a `Field`, null is returned. Parameters: `calendarField` \- Calendar field constant Returns: Field instance representing calendarField. Throws: `[IllegalArgumentException](../../java/lang/IllegalArgumentException.html "class in java.lang")` \- if `calendarField` is not the value of a `Calendar` field constant. See Also: [Calendar](../../java/util/Calendar.html "class in java.util") * #### getCalendarField public int getCalendarField() Returns the `Calendar` field associated with this attribute. For example, if this represents the hours field of a `Calendar`, this would return`Calendar.HOUR`. If there is no corresponding`Calendar` constant, this will return -1. Returns: Calendar constant for this field See Also: [Calendar](../../java/util/Calendar.html "class in java.util") * #### readResolve protected [Object](../../java/lang/Object.html "class in java.lang") readResolve() throws [InvalidObjectException](../../java/io/InvalidObjectException.html "class in java.io") Resolves instances being deserialized to the predefined constants. Overrides: `[readResolve](../../java/text/AttributedCharacterIterator.Attribute.html#readResolve--)` in class `[AttributedCharacterIterator.Attribute](../../java/text/AttributedCharacterIterator.Attribute.html "class in java.text")` Returns: resolved DateFormat.Field constant Throws: `[InvalidObjectException](../../java/io/InvalidObjectException.html "class in java.io")` \- if the constant could not be resolved.
