# NumberRangeFormatterSettings

`public abstract class NumberRangeFormatterSettings`
`extends Object` ``

java.lang.Object
↳ | android.icu.number.NumberRangeFormatterSettings<T extends android.icu.number.NumberRangeFormatterSettings<?>>

Known direct subclasses LocalizedNumberRangeFormatter, UnlocalizedNumberRangeFormatter
LocalizedNumberRangeFormatter | A NumberRangeFormatter that has a locale associated with it; this means .formatRange() methods are available.
UnlocalizedNumberRangeFormatter | A NumberRangeFormatter that does not yet have a locale.

An abstract base class for specifying settings related to number formatting. This class is implemented by `UnlocalizedNumberRangeFormatter` and `LocalizedNumberRangeFormatter`. This class is not intended for public subclassing.

## Summary

### Public methods
`T` | `collapse(NumberRangeFormatter.RangeCollapse collapse)` Sets the aggressiveness of "collapsing" fields across the range separator.
`boolean` | `equals(Object other)` Indicates whether some other object is "equal to" this one.
`int` | `hashCode()` Returns a hash code value for the object.
`T` | `identityFallback(NumberRangeFormatter.RangeIdentityFallback identityFallback)` Sets the behavior when the two sides of the range are the same.
`T` | `numberFormatterBoth(UnlocalizedNumberFormatter formatter)` Sets the NumberFormatter instance to use for the numbers in the range.
`T` | `numberFormatterFirst(UnlocalizedNumberFormatter formatterFirst)` Sets the NumberFormatter instance to use for the first number in the range.
`T` | `numberFormatterSecond(UnlocalizedNumberFormatter formatterSecond)` Sets the NumberFormatter instances to use for the second number in the range.

### Inherited methods
From class `java.lang.Object`
`Object` | `clone()` Creates and returns a copy of this object.
`boolean` | `equals(Object obj)` Indicates whether some other object is "equal to" this one.
`void` | `finalize()` Called by the garbage collector on an object when garbage collection determines that there are no more references to the object.
`final Class<?>` | `getClass()` Returns the runtime class of this `Object`.
`int` | `hashCode()` Returns a hash code value for the object.
`final void` | `notify()` Wakes up a single thread that is waiting on this object's monitor.
`final void` | `notifyAll()` Wakes up all threads that are waiting on this object's monitor.
`String` | `toString()` Returns a string representation of the object.
`final void` | `wait(long timeout, int nanos)` Causes the current thread to wait until another thread invokes the `notify()` method or the `notifyAll()` method for this object, or some other thread interrupts the current thread, or a certain amount of real time has elapsed.
`final void` | `wait(long timeout)` Causes the current thread to wait until either another thread invokes the `notify()` method or the `notifyAll()` method for this object, or a specified amount of time has elapsed.
`final void` | `wait()` Causes the current thread to wait until another thread invokes the `notify()` method or the `notifyAll()` method for this object.

## Public methods

### collapse

    public T collapse (NumberRangeFormatter.RangeCollapse collapse)

Sets the aggressiveness of "collapsing" fields across the range separator. Possible values:

- ALL: "3-5K miles"
- UNIT: "3K - 5K miles"
- NONE: "3K miles - 5K miles"
- AUTO: usually UNIT or NONE, depending on the locale and formatter settings

The default value is AUTO.

Parameters
`collapse` | `NumberRangeFormatter.RangeCollapse`: The collapsing strategy to use for this range.

Returns
`T` | The fluent chain.

### equals

    public boolean equals (Object other)

Indicates whether some other object is "equal to" this one.

The `equals` method implements an equivalence relation on non-null object references:

- It is reflexive: for any non-null reference value `x`, `x.equals(x)` should return `true`.
- It is symmetric: for any non-null reference values `x` and `y`, `x.equals(y)` should return `true` if and only if `y.equals(x)` returns `true`.
- It is transitive: for any non-null reference values `x`, `y`, and `z`, if `x.equals(y)` returns `true` and `y.equals(z)` returns `true`, then `x.equals(z)` should return `true`.
- It is consistent: for any non-null reference values `x` and `y`, multiple invocations of `x.equals(y)` consistently return `true` or consistently return `false`, provided no information used in `equals` comparisons on the objects is modified.
- For any non-null reference value `x`, `x.equals(null)` should return `false`.

The `equals` method for class `Object` implements the most discriminating possible equivalence relation on objects; that is, for any non-null reference values `x` and `y`, this method returns `true` if and only if `x` and `y` refer to the same object (`x == y` has the value `true`).

Note that it is generally necessary to override the `hashCode` method whenever this method is overridden, so as to maintain the general contract for the `hashCode` method, which states that equal objects must have equal hash codes.

Parameters
`other` | `Object`: the reference object with which to compare.

Returns
`boolean` | `true` if this object is the same as the obj argument; `false` otherwise.

### hashCode

    public int hashCode ()

Returns a hash code value for the object. This method is supported for the benefit of hash tables such as those provided by `HashMap`.

The general contract of `hashCode` is:

- Whenever it is invoked on the same object more than once during an execution of a Java application, the `hashCode` method must consistently return the same integer, provided no information used in `equals` comparisons on the object is modified. This integer need not remain consistent from one execution of an application to another execution of the same application.
- If two objects are equal according to the `equals(Object)` method, then calling the `hashCode` method on each of the two objects must produce the same integer result.
- It is not required that if two objects are unequal according to the `equals(java.lang.Object)` method, then calling the `hashCode` method on each of the two objects must produce distinct integer results. However, the programmer should be aware that producing distinct integer results for unequal objects may improve the performance of hash tables.

As much as is reasonably practical, the hashCode method defined by class `Object` does return distinct integers for distinct objects. (This is typically implemented by converting the internal address of the object into an integer, but this implementation technique is not required by the Java™ programming language.)

Returns
`int` | a hash code value for this object.

### identityFallback

    public T identityFallback (NumberRangeFormatter.RangeIdentityFallback identityFallback)

Sets the behavior when the two sides of the range are the same. This could happen if the same two numbers are passed to the formatRange function, or if different numbers are passed to the function but they become the same after rounding rules are applied. Possible values:

- SINGLE_VALUE: "5 miles"
- APPROXIMATELY_OR_SINGLE_VALUE: "~5 miles" or "5 miles", depending on whether the number was the same before rounding was applied
- APPROXIMATELY: "~5 miles"
- RANGE: "5-5 miles" (with collapse=UNIT)

The default value is APPROXIMATELY.

Parameters
`identityFallback` | `NumberRangeFormatter.RangeIdentityFallback`: The strategy to use when formatting two numbers that end up being the same.

Returns
`T` | The fluent chain.

### numberFormatterBoth

    public T numberFormatterBoth (UnlocalizedNumberFormatter formatter)

Sets the NumberFormatter instance to use for the numbers in the range. The same formatter is applied to both sides of the range.

The NumberFormatter instances must not have a locale applied yet; the locale specified on the NumberRangeFormatter will be used.

Parameters
`formatter` | `UnlocalizedNumberFormatter`: The formatter to use for both numbers in the range.

Returns
`T` | The fluent chain.

- `NumberFormatter`
- `NumberRangeFormatter`

### numberFormatterFirst

    public T numberFormatterFirst (UnlocalizedNumberFormatter formatterFirst)

Sets the NumberFormatter instance to use for the first number in the range.

The NumberFormatter instance must not have a locale applied yet; the locale specified on the NumberRangeFormatter will be used.

Parameters
`formatterFirst` | `UnlocalizedNumberFormatter`: The formatter to use for the first number in the range.

Returns
`T` | The fluent chain.

- `NumberFormatter`
- `NumberRangeFormatter`

### numberFormatterSecond

    public T numberFormatterSecond (UnlocalizedNumberFormatter formatterSecond)

Sets the NumberFormatter instances to use for the second number in the range.

The NumberFormatter instance must not have a locale applied yet; the locale specified on the NumberRangeFormatter will be used.

Parameters
`formatterSecond` | `UnlocalizedNumberFormatter`: The formatter to use for the second number in the range.

Returns
`T` | The fluent chain.
