FloatProperty

Kotlin |Java

abstract class FloatProperty<T : Any!> : Property<T, Float!>

kotlin.Any
↳	android.util.Property<T, kotlin.Float>
	↳	android.util.FloatProperty

An implementation of android.util.Property to be used specifically with fields of type float. This type-specific subclass enables performance benefit by allowing calls to a setValue() function that takes the primitive float type and avoids autoboxing and other overhead associated with the Float class.

Summary

Public constructors
`FloatProperty(name: String!)`

Public methods
Unit	`set(object: T, value: Float!)`
abstract Unit	`setValue(object: T, value: Float)` A type-specific variant of `set(java.lang.Object,java.lang.Float)` that is faster when dealing with fields of type `float`.

Inherited functions

From class Property

`V`	`get(object: T)` Returns the current value that this property represents on the given `object`.
`String!`	`getName()` Returns the name for this property.
`Class<V>!`	`getType()` Returns the type for this property.
`Boolean`	`isReadOnly()` Returns true if the `set(java.lang.Object,java.lang.Object)` method does not set the value on the target object (in which case the `set()` method should throw a `NoSuchPropertyException` exception). This may happen if the Property wraps functionality that allows querying the underlying value but not setting it. For example, the `of(java.lang.Class,java.lang.Class,java.lang.String)` factory method may return a Property with name "foo" for an object that has only a `getFoo()` or `isFoo()` method, but no matching `setFoo()` method.
`Property<T, V>!`	`of(hostType: Class<T>!, valueType: Class<V>!, name: String!)` This factory method creates and returns a Property given the `class` and `name` parameters, where the `"name"` parameter represents either: a public `getName()` method on the class which takes no arguments, plus an optional public `setName()` method which takes a value of the same type returned by `getName()` a public `isName()` method on the class which takes no arguments, plus an optional public `setName()` method which takes a value of the same type returned by `isName()` a public `name` field on the class If either of the get/is method alternatives is found on the class, but an appropriate `setName()` method is not found, the `Property` will be `readOnly`. Calling the `set(java.lang.Object,java.lang.Object)` method on such a property is allowed, but will have no effect. If neither the methods nor the field are found on the class a `NoSuchPropertyException` exception will be thrown.
