SimpleOptionalFloatProperty

open class SimpleOptionalFloatProperty(initialValue: Float?, bean: Any? = null, beanName: String? = null) : SimpleProperty<Float?> , OptionalFloatProperty

Boilerplate which avoids having to use generics.

Similar to SimpleFloatProperty, but the value can also be null.

Constructors

SimpleOptionalFloatProperty

constructor(initialValue: Float?, bean: Any? = null, beanName: String? = null)

Properties

open override val bean: Any?

open override val beanName: String?

open override var value: Float?

Functions

addBindChangeListener

open fun addBindChangeListener(lambda: (ObservableValue<Float?>, Float?, Float?) -> Unit): ChangeListener<Float?, ObservableValue<Float?>>

open override fun addBindChangeListener(listener: ChangeListener<Float?, ObservableValue<Float?>>)

Identical to addChangeListener, but these listeners are guaranteed to fire BEFORE other listeners. These should be used for the sole purpose of updating single ObservableValues which are dependent on this ObservableValue. This helps (but doesn't guarantee) that properties change atomically. i.e. when one property changes, a related property also changes before other (regular) listeners fire. Therefore, the (regular) listeners cannot read inconsistent values.

addBindListener

open fun addBindListener(lambda: (Observable) -> Unit): InvalidationListener

open override fun addBindListener(listener: InvalidationListener)

Identical to addListener, but these listeners are guaranteed to fire BEFORE regular listeners. These should be used for the sole purpose of updating other ObservableValues which are dependent on this Observable.

addChangeListener

open fun addChangeListener(lambda: (ObservableValue<Float?>, Float?, Float?) -> Unit): ChangeListener<Float?, ObservableValue<Float?>>

open override fun addChangeListener(listener: ChangeListener<Float?, ObservableValue<Float?>>)

open fun addListener(lambda: (Observable) -> Unit): InvalidationListener

open override fun addListener(listener: InvalidationListener)

addWeakChangeListener

open fun addWeakChangeListener(lambda: (ObservableValue<Float?>, Float?, Float?) -> Unit): ChangeListener<Float?, ObservableValue<Float?>>

addWeakListener

open fun addWeakListener(lambda: (Observable) -> Unit): InvalidationListener

fun <T : Any> ObservableValue<T>.asNullable(): ObservableValue<T?>

Converts an ObservableValue, with a non-nullable to value, to an ObservableValue whose value IS nullable.

open fun asReadOnly(): ReadOnlyOptionalFloatProperty

Returns a read-only view of this mutable OptionalFloatProperty. Typical usage :

fun <V> Property<V>.asReadOnly(): ReadOnlyPropertyWrapper<V, Property<V>>

bidirectionalBind

open override fun bidirectionalBind(other: Property<Float?>): BidirectionalBind

This property's value is set to other's value, and then both values are bound to each other. i.e. if either property changes, the other will also change.

open override fun <B> bidirectionalBind(other: Property<B>, converter: Converter<Float?, B>): BidirectionalBind

This property's value is set to other's value, and then both values are bound to each other. i.e. if either property changes, the other will also change.

bidirectionalUnbind

open override fun bidirectionalUnbind(other: Property<*>?)

Removes a bidirectional bind created using bidirectionalBind.

open fun <T : Float?> bindCastTo(bindTo: ObservableValue<T>)

This is the same as bindTo, but casting this to Property<T>, suppressing the unchecked cast. I believe this is fine in all cases.

open override fun bindTo(to: ObservableValue<Float?>)

The value of this property is bound to the value of property to.

open fun defaultOf(defaultValue: Float): ObservableFloat

open fun equalTo(other: Float?): ObservableBoolean

open fun equalTo(other: ObservableValue<Float?>): ObservableBoolean

open operator fun getValue(thisRef: Any, kProperty: KProperty<*>): Float?

Lets us declare a val using a for the value of this property, using this as a delegate. e.g.

open override fun isBound(): Boolean

open fun isNotNull(): ObservableBoolean

open fun isNull(): ObservableBoolean

open fun notEqualTo(other: Float?): ObservableBoolean

open fun notEqualTo(other: ObservableValue<Float?>): ObservableBoolean

notSameInstance

open fun notSameInstance(other: Float?): ObservableBoolean

open fun notSameInstance(other: ObservableValue<Float?>): ObservableBoolean

removeChangeListener

open override fun removeChangeListener(listener: ChangeListener<Float?, ObservableValue<Float?>>)

open override fun removeListener(listener: InvalidationListener)

replaceNullWith

fun <T : Any> ObservableValue<T?>.replaceNullWith(defaultValue: T): ObservableValue<T>

Converts an ObservableValue, with a nullable to value, to an ObservableValue whose value is NOT nullable, by supplying a defaultValue.

open fun sameInstance(other: Float?): ObservableBoolean

open fun sameInstance(other: ObservableValue<Float?>): ObservableBoolean

open operator fun setValue(thisRef: Any, kProperty: KProperty<*>, newValue: Float?)

Lets us declare a var for the value of this property. e.g.

operator fun ObservableOptionalFloat.times(constant: Float): ObservableOptionalFloat

toObservableString

open fun toObservableString(): ObservableString

open fun toObservableString(nullString: String): ObservableString

open override fun toString(): String

open override fun unbind()
