NumberFormat.Field

AI-generated Key Takeaways

NumberFormat.Field defines constants used as attribute keys in AttributedCharacterIterator and field identifiers in FieldPosition.
These constants identify various parts of a formatted number like currency, decimal separator, exponent, fraction, and grouping separator.
The class provides predefined constants for each field, allowing developers to access and manipulate specific number elements.
NumberFormat.Field inherits from Format.Field and AttributedCharacterIterator.Attribute, extending their functionality for number formatting.
It includes a protected constructor and a readResolve method to handle object creation and deserialization.

public static class NumberFormat.Field extends Format.Field

Defines constants that are used as attribute keys in the AttributedCharacterIterator returned from NumberFormat.formatToCharacterIterator and as field identifiers in FieldPosition.

Inherited Method Summary

From class java.text.AttributedCharacterIterator.Attribute

final boolean	equals(Object obj) Compares two objects for equality.
String	getName() Returns the name of the attribute.
final int	hashCode() Returns a hash code value for the object.
Object	readResolve() Resolves instances being deserialized to the predefined constants.
String	toString() Returns a string representation of the object.

From class java.lang.Object

Object	clone() Creates and returns a copy of this `Object`.
boolean	equals(Object obj) Compares this instance with the specified object and indicates if they are equal.
void	finalize() Invoked when the garbage collector has detected that this instance is no longer reachable.
final Class<?>	getClass() Returns the unique instance of `Class` that represents this object's class.
int	hashCode() Returns an integer hash code for this object.
final void	notify() Causes a thread which is waiting on this object's monitor (by means of calling one of the `wait()` methods) to be woken up.
final void	notifyAll() Causes all threads which are waiting on this object's monitor (by means of calling one of the `wait()` methods) to be woken up.
String	toString() Returns a string containing a concise, human-readable description of this object.
final void	wait(long timeout, int nanos) Causes the calling thread to wait until another thread calls the `notify()` or `notifyAll()` method of this object or until the specified timeout expires.
final void	wait(long timeout) Causes the calling thread to wait until another thread calls the `notify()` or `notifyAll()` method of this object or until the specified timeout expires.
final void	wait() Causes the calling thread to wait until another thread calls the `notify()` or `notifyAll()` method of this object.
