| ↳ | [java.awt.font.NumericShaper](https://developer.android.com/reference/kotlin/java/awt/font/NumericShaper#) |
The class is used to convert Latin-1 (European) digits to other Unicode decimal digits. Users of this class will primarily be people who wish to present data using national digit shapes, but find it more convenient to represent the data internally using Latin-1 (European) digits. This does not interpret the deprecated numeric shape selector character (U+206E).
Instances of`NumericShaper`are typically applied as attributes to text with the[NUMERIC_SHAPING](https://developer.android.com/reference/kotlin/java/awt/font/TextAttribute#NUMERIC_SHAPING:java.awt.font.TextAttribute)attribute of the`TextAttribute`class. For example, this code snippet causes a`TextLayout`to shape European digits to Arabic in an Arabic context:
```kotlin
Map map = new HashMap();
map.put(TextAttribute.NUMERIC_SHAPING,
NumericShaper.getContextualShaper(NumericShaper.ARABIC));
FontRenderContext frc = ...;
TextLayout layout = new TextLayout(text, map, frc);
layout.draw(g2d, x, y);
```
It is also possible to perform numeric shaping explicitly using instances of`NumericShaper`, as this code snippet demonstrates:
```kotlin
char[] text = ...;
// shape all EUROPEAN digits (except zero) to ARABIC digits
NumericShaper shaper = NumericShaper.getShaper(NumericShaper.ARABIC);
shaper.shape(text, start, count);
// shape European digits to ARABIC digits if preceding text is Arabic, or
// shape European digits to TAMIL digits if preceding text is Tamil, or
// leave European digits alone if there is no preceding text, or
// preceding text is neither Arabic nor Tamil
NumericShaper shaper =
NumericShaper.getContextualShaper(NumericShaper.ARABIC |
NumericShaper.TAMIL,
NumericShaper.EUROPEAN);
shaper.shape(text, start, count);
```
**Bit mask- and enum-based Unicode ranges**
This class supports two different programming interfaces to represent Unicode ranges for script-specific digits: bit mask-based ones, such as[NumericShaper.ARABIC](https://developer.android.com/reference/kotlin/java/awt/font/NumericShaper#ARABIC:kotlin.Int), and enum-based ones, such as[NumericShaper.Range.ARABIC](https://developer.android.com/reference/kotlin/java/awt/font/NumericShaper.Range). Multiple ranges can be specified by ORing bit mask-based constants, such as:
```kotlin
NumericShaper.ARABIC | NumericShaper.TAMIL
```
or creating a`Set`with the[NumericShaper.Range](https://developer.android.com/reference/kotlin/java/awt/font/NumericShaper.Range)constants, such as:
```kotlin
EnumSet.of(NumericShaper.Scirpt.ARABIC, NumericShaper.Range.TAMIL)
```
The enum-based ranges are a super set of the bit mask-based ones.
If the two interfaces are mixed (including serialization), Unicode range values are mapped to their counterparts where such mapping is possible, such as`NumericShaper.Range.ARABIC`from/to`NumericShaper.ARABIC`. If any unmappable range values are specified, such as`NumericShaper.Range.BALINESE`, those ranges are ignored.
**Decimal Digits Precedence**
A Unicode range may have more than one set of decimal digits. If multiple decimal digits sets are specified for the same Unicode range, one of the sets will take precedence as follows.
| Unicode Range | `NumericShaper`Constants | Precedence |

### equals
Added in[API level 1](https://developer.android.com/guide/topics/manifest/uses-sdk-element.html#ApiLevels)
```
fun equals(other: Any?): Boolean
```
Returns`true`if the specified object is an instance of`NumericShaper`and shapes identically to this one, regardless of the range representations, the bit mask or the enum. For example, the following code produces`"true"`.
```kotlin
NumericShaper ns1 = NumericShaper.getShaper(NumericShaper.ARABIC);
NumericShaper ns2 = NumericShaper.getShaper(NumericShaper.Range.ARABIC);
System.out.println(ns1.equals(ns2));
```
| Parameters ||
|-------|--------------------------------------------------------|
| `obj` | the reference object with which to compare. |
| `o` | the specified object to compare to this`NumericShaper` |
| Return ||
|------------------------------------------------------------------------------------|-----------------------------------------------------------------------------------------|
| [Boolean](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-boolean/index.html) | `true`if`o`is an instance of`NumericShaper`and shapes in the same way;`false`otherwise. |

### getContextualShaper
Added in[API level 1](https://developer.android.com/guide/topics/manifest/uses-sdk-element.html#ApiLevels)
```
static fun getContextualShaper(ranges: Int): NumericShaper!
```
Returns a contextual shaper for the provided unicode range(s). Latin-1 (EUROPEAN) digits are converted to the decimal digits corresponding to the range of the preceding text, if the range is one of the provided ranges. Multiple ranges are represented by or-ing the values together, such as,`NumericShaper.ARABIC | NumericShaper.THAI`. The shaper assumes EUROPEAN as the starting context, that is, if EUROPEAN digits are encountered before any strong directional text in the string, the context is presumed to be EUROPEAN, and so the digits will not shape.
| Parameters ||
|----------|---------------------------------------------------------------------------------------------------------|
| `ranges` | [Int](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-int/index.html):the specified Unicode ranges |
| Return ||
|-----------------------------------------------------------------------------------------------|-----------------------------------|
| [NumericShaper](https://developer.android.com/reference/kotlin/java/awt/font/NumericShaper#)! | a shaper for the specified ranges |
### getContextualShaper
Added in[API level 1](https://developer.android.com/guide/topics/manifest/uses-sdk-element.html#ApiLevels)
```
static fun getContextualShaper(
ranges: Int,
defaultContext: Int
): NumericShaper!
```
Returns a contextual shaper for the provided unicode range(s). Latin-1 (EUROPEAN) digits will be converted to the decimal digits corresponding to the range of the preceding text, if the range is one of the provided ranges. Multiple ranges are represented by or-ing the values together, for example,`NumericShaper.ARABIC | NumericShaper.THAI`. The shaper uses defaultContext as the starting context.
| Parameters ||
|------------------|----------------------------------------------------------------------------------------------------------------------------------|
| `ranges` | [Int](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-int/index.html):the specified Unicode ranges |
| `defaultContext` | [Int](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-int/index.html):the starting context, such as`NumericShaper.EUROPEAN` |
| Return ||
|-----------------------------------------------------------------------------------------------|--------------------------------------------|
| [NumericShaper](https://developer.android.com/reference/kotlin/java/awt/font/NumericShaper#)! | a shaper for the specified Unicode ranges. |
| Exceptions ||
|--------------------------------------|--------------------------------------------------------------|
| `java.lang.IllegalArgumentException` | if the specified`defaultContext`is not a single valid range. |
### getContextualShaper
Added in[API level 24](https://developer.android.com/guide/topics/manifest/uses-sdk-element.html#ApiLevels)
```
static fun getContextualShaper(ranges: MutableSet!): NumericShaper!
```
Returns a contextual shaper for the provided Unicode range(s). The Latin-1 (EUROPEAN) digits are converted to the decimal digits corresponding to the range of the preceding text, if the range is one of the provided ranges.
The shaper assumes EUROPEAN as the starting context, that is, if EUROPEAN digits are encountered before any strong directional text in the string, the context is presumed to be EUROPEAN, and so the digits will not shape.

```
static fun getContextualShaper(
ranges: MutableSet!,
defaultContext: NumericShaper.Range!
): NumericShaper!
```
Returns a contextual shaper for the provided Unicode range(s). The Latin-1 (EUROPEAN) digits will be converted to the decimal digits corresponding to the range of the preceding text, if the range is one of the provided ranges. The shaper uses`defaultContext`as the starting context.
