Kotlin |Java

open class FloatProperty : Property<Parallax<Property<*, *>!>!, Float!>

kotlin.Any
↳	android.util.Property<androidx.leanback.widget.Parallax<android.util.Property<, >>, kotlin.Float>
	↳	androidx.leanback.widget.Parallax.FloatProperty

FloatProperty provide access to an index based integer type property inside Parallax. The FloatProperty typically represents UI element position inside Parallax.

Summary

Constants
static Float	`UNKNOWN_AFTER` Property value is unknown and it's larger than `Parallax#getMaxValue()`.
static Float	`UNKNOWN_BEFORE` Property value is unknown and it's smaller than minimal value of Parallax.

Public constructors
`<init>(name: String!, index: Int)` Constructor.

Public methods
Parallax.PropertyMarkerValue<Any!>!	`at(offsetValue: Float, fractionOfMaxParentVisibleSize: Float)` Create an `PropertyMarkerValue` object by multiplying the fraction with `Parallax#getMaxValue()` and adding offsetValue to it.
Parallax.PropertyMarkerValue<Any!>!	`atAbsolute(markerValue: Float)` Creates an `PropertyMarkerValue` object for the absolute marker value.
Parallax.PropertyMarkerValue<Any!>!	`atFraction(fractionOfMaxParentVisibleSize: Float)` Creates an `PropertyMarkerValue` object for a fraction of `Parallax#getMaxValue()`.
Parallax.PropertyMarkerValue<Any!>!	`atMax()` Creates an `PropertyMarkerValue` object for the marker value representing `Parallax#getMaxValue()`.
Parallax.PropertyMarkerValue<Any!>!	`atMin()` Creates an `PropertyMarkerValue` object for the marker value representing 0.
Float!	`get(object: Parallax<Property<, >!>!)`
Int	`getIndex()`
Float	`getValue(object: Parallax<Property<, >!>!)` Fast version of get() method that returns a primitive int value of the Property.
Unit	`set(object: Parallax<Property<, >!>!, value: Float!)`
Unit	`setValue(object: Parallax<Property<, >!>!, value: Float)` Fast version of set() method that takes a primitive float value into the Property.

Constants

UNKNOWN_AFTER

static val UNKNOWN_AFTER: Float

Property value is unknown and it's larger than Parallax#getMaxValue(). For example if a child is not created and after the last visible child of RecyclerView.

Value: Float.MAX_VALUE

UNKNOWN_BEFORE

static val UNKNOWN_BEFORE: Float

Property value is unknown and it's smaller than minimal value of Parallax. For example if a child is not created and before the first visible child of RecyclerView.

Value: -Float.MAX_VALUE

Public constructors

<init>

FloatProperty(name: String!, index: Int)

Constructor.

Parameters
`name`	String!: Name of this Property.
`index`	String!: Index of this Property inside `Parallax`.

Public methods

at

fun at(offsetValue: Float, fractionOfMaxParentVisibleSize: Float): Parallax.PropertyMarkerValue<Any!>!

Create an PropertyMarkerValue object by multiplying the fraction with Parallax#getMaxValue() and adding offsetValue to it.

Parameters
`offsetValue`	Float: An offset float value to be added to marker value.
`fractionOfMaxParentVisibleSize`	Float: 0 to 1 fraction to multiply with `Parallax#getMaxValue()` for the marker value.

Return
Parallax.PropertyMarkerValue<Any!>!: A new `PropertyMarkerValue` object.

atAbsolute

fun atAbsolute(markerValue: Float): Parallax.PropertyMarkerValue<Any!>!

Creates an PropertyMarkerValue object for the absolute marker value.

Parameters
`markerValue`	Float: The float marker value.

Return
Parallax.PropertyMarkerValue<Any!>!: A new `PropertyMarkerValue` object.

atFraction

fun atFraction(fractionOfMaxParentVisibleSize: Float): Parallax.PropertyMarkerValue<Any!>!

Creates an PropertyMarkerValue object for a fraction of Parallax#getMaxValue().

Parameters
`fractionOfMaxParentVisibleSize`	Float: 0 to 1 fraction to multiply with `Parallax#getMaxValue()` for the marker value.

Return
Parallax.PropertyMarkerValue<Any!>!: A new `PropertyMarkerValue` object.

atMax

fun atMax(): Parallax.PropertyMarkerValue<Any!>!

Creates an PropertyMarkerValue object for the marker value representing Parallax#getMaxValue().

Return
Parallax.PropertyMarkerValue<Any!>!: A new `PropertyMarkerValue` object.

atMin

fun atMin(): Parallax.PropertyMarkerValue<Any!>!

Creates an PropertyMarkerValue object for the marker value representing 0.

Return
Parallax.PropertyMarkerValue<Any!>!: A new `PropertyMarkerValue` object.

get

fun get(object: Parallax<Property<*, *>!>!): Float!

getIndex

fun getIndex(): Int

Return
Int: Index of this Property in `Parallax`.

getValue

fun getValue(object: Parallax<Property<*, *>!>!): Float

Fast version of get() method that returns a primitive int value of the Property.

Parameters
`object`	Parallax<Property<, >!>!: The Parallax object that owns this Property.

Return
Float: Float value of the Property.

set

fun set(object: Parallax<Property<*, *>!>!, value: Float!): Unit

setValue

fun setValue(object: Parallax<Property<*, *>!>!, value: Float): Unit

Fast version of set() method that takes a primitive float value into the Property.

Parameters
`object`	Parallax<Property<, >!>!: The Parallax object that owns this Property.
`value`	Parallax<Property<, >!>!: Float value of the Property.
