Discriminator

class Discriminator : Parcelable

Represents a Matter discriminator.

A discriminator may either be a long discriminator (12 bits) or a short discriminator (4 bits). For instance, a manual pairing code specifies only a short discriminator, which provides less uniqueness than the long discriminator provided in the QR code or NFC tag data.

Summary

Public functions
`Boolean`	`equals(other: Any?)`
`java-static Discriminator!`	`forLongValue(longDiscriminator: @IntRange(from = 0, to = 4095) Int)` Creates a new `Discriminator` representing a full 12-bit discriminator (such as for a QR code).
`java-static Discriminator!`	`forShortValue(shortDiscriminator: @IntRange(from = 0, to = 4095) Int)` Creates a new `Discriminator` representing an abbreviated value (such as for a manual pairing code).
`Int`	`hashCode()`
`Boolean`	`matches(other: Discriminator!)` Returns true if the discriminator is a match for another discriminator.
`String!`	`toString()`
`Unit`	`writeToParcel(dest: Parcel!, flags: Int)`

Public functions

equals

fun equals(other: Any?): Boolean

forLongValue

java-static fun forLongValue(longDiscriminator: @IntRange(from = 0, to = 4095) Int): Discriminator!

Creates a new Discriminator representing a full 12-bit discriminator (such as for a QR code).

Parameters
`longDiscriminator: @IntRange(from = 0, to = 4095) Int`	the 12-bit discriminator value

Throws
`java.lang.IllegalArgumentException`	if the given value is negative, or greater than 12 bits

forShortValue

java-static fun forShortValue(shortDiscriminator: @IntRange(from = 0, to = 4095) Int): Discriminator!

Creates a new Discriminator representing an abbreviated value (such as for a manual pairing code). For this discriminator, only the upper 4 bits of the 12-bit value will be used for comparison in matches.

Parameters
`shortDiscriminator: @IntRange(from = 0, to = 4095) Int`	the 12-bit discriminator value, of which only the upper 4-bits will be kept. For example, given 0xFAB, the value will be masked to 0xF00)

Throws
`java.lang.IllegalArgumentException`	if the given value is negative, or greater than 12 bits

hashCode

fun hashCode(): Int

matches

fun matches(other: Discriminator!): Boolean

Returns true if the discriminator is a match for another discriminator. If both are long discriminators, then this is a simple equality test. However, if one or the other being compared is an abbreviated discriminator, then only the upper 4 bits of the discriminator are considered in the comparison.

Note that this is different behavior from equals which does not incorporate the mask into the equality test.

Parameters
`other: Discriminator!`	the discriminator to compare to

toString

fun toString(): String!

writeToParcel

fun writeToParcel(dest: Parcel!, flags: Int): Unit
