# ValueRange Added in[API level 26](https://developer.android.com/guide/topics/manifest/uses-sdk-element.html#ApiLevels) # ValueRange ``` class ValueRange : Serializable ``` |---|----------------------------------------------------------------------------------------------------------------| | [kotlin.Any](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-any/index.html) || | ↳ | [java.time.temporal.ValueRange](https://developer.android.com/reference/kotlin/java/time/temporal/ValueRange#) | The range of valid values for a date-time field. All[TemporalField](https://developer.android.com/reference/kotlin/java/time/temporal/TemporalField)instances have a valid range of values. For example, the ISO day-of-month runs from 1 to somewhere between 28 and 31. This class captures that valid range. It is important to be aware of the limitations of this class. Only the minimum and maximum values are provided. It is possible for there to be invalid values within the outer range. For example, a weird field may have valid values of 1, 2, 4, 6, 7, thus have a range of '1 - 7', despite that fact that values 3 and 5 are invalid. Instances of this class are not tied to a specific field. ## Summary | Public methods || |----------------------------------------------------------------------------------------------------|-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------| | [Int](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-int/index.html) | [checkValidIntValue](https://developer.android.com/reference/kotlin/java/time/temporal/ValueRange#checkValidIntValue(kotlin.Long,%20java.time.temporal.TemporalField))`(`value:` `[Long](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-long/index.html)`, `field:` `[TemporalField](https://developer.android.com/reference/kotlin/java/time/temporal/TemporalField)!`)` Checks that the specified value is valid and fits in an`int`. | | [Long](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-long/index.html) | [checkValidValue](https://developer.android.com/reference/kotlin/java/time/temporal/ValueRange#checkValidValue(kotlin.Long,%20java.time.temporal.TemporalField))`(`value:` `[Long](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-long/index.html)`, `field:` `[TemporalField](https://developer.android.com/reference/kotlin/java/time/temporal/TemporalField)!`)` Checks that the specified value is valid. | | [Boolean](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-boolean/index.html) | [equals](https://developer.android.com/reference/kotlin/java/time/temporal/ValueRange#equals(kotlin.Any))`(`other:` `[Any](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-any/index.html)?`)` Checks if this range is equal to another range. | | [Long](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-long/index.html) | [getLargestMinimum](https://developer.android.com/reference/kotlin/java/time/temporal/ValueRange#getLargestMinimum())`()` Gets the largest possible minimum value that the field can take. | | [Long](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-long/index.html) | [getMaximum](https://developer.android.com/reference/kotlin/java/time/temporal/ValueRange#getMaximum())`()` Gets the maximum value that the field can take. | | [Long](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-long/index.html) | [getMinimum](https://developer.android.com/reference/kotlin/java/time/temporal/ValueRange#getMinimum())`()` Gets the minimum value that the field can take. | | [Long](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-long/index.html) | [getSmallestMaximum](https://developer.android.com/reference/kotlin/java/time/temporal/ValueRange#getSmallestMaximum())`()` Gets the smallest possible maximum value that the field can take. | | [Int](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-int/index.html) | [hashCode](https://developer.android.com/reference/kotlin/java/time/temporal/ValueRange#hashCode())`()` A hash code for this range. | | [Boolean](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-boolean/index.html) | [isFixed](https://developer.android.com/reference/kotlin/java/time/temporal/ValueRange#isFixed())`()` Is the value range fixed and fully known. | | [Boolean](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-boolean/index.html) | [isIntValue](https://developer.android.com/reference/kotlin/java/time/temporal/ValueRange#isIntValue())`()` Checks if all values in the range fit in an`int`. | | [Boolean](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-boolean/index.html) | [isValidIntValue](https://developer.android.com/reference/kotlin/java/time/temporal/ValueRange#isValidIntValue(kotlin.Long))`(`value:` `[Long](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-long/index.html)`)` Checks if the value is within the valid range and that all values in the range fit in an`int`. | | [Boolean](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-boolean/index.html) | [isValidValue](https://developer.android.com/reference/kotlin/java/time/temporal/ValueRange#isValidValue(kotlin.Long))`(`value:` `[Long](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-long/index.html)`)` Checks if the value is within the valid range. | | static[ValueRange](https://developer.android.com/reference/kotlin/java/time/temporal/ValueRange#)!

The comparison is based on the four values, minimum, largest minimum, smallest maximum and maximum. Only objects of type`ValueRange`are compared, other types return false. | Parameters || |-------|-----------------------------------------| | `obj` | the object to check, null returns false | | Return || |------------------------------------------------------------------------------------|------------------------------------------| | [Boolean](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-boolean/index.html) | true if this is equal to the other range | ### getLargestMinimum Added in[API level 26](https://developer.android.com/guide/topics/manifest/uses-sdk-element.html#ApiLevels) ``` fun getLargestMinimum(): Long ``` Gets the largest possible minimum value that the field can take.
