IndirectObservableBoolean

class IndirectObservableBoolean<P : Any>(parentProperty: ObservableValue<P>, getObservable: (P) -> ObservableValue<Boolean>) : IndirectObservableValue<P, Boolean> , ObservableBoolean

Boilerplate for a non-generic version of IndirectObservableValue.

Constructors

IndirectObservableBoolean

constructor(parentProperty: ObservableValue<P>, getObservable: (P) -> ObservableValue<Boolean>)

Properties

val getObservable: (P) -> ObservableValue<Boolean>

A lambda to get the ObservableValue we are interested in tracking, from the value of parentProperty.

val parentProperty: ObservableValue<P>

open override val value: Boolean

Functions

addBindChangeListener

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

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.

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

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 override fun addChangeListener(listener: ChangeListener<Boolean, ObservableValue<Boolean>>)

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

fun addDependent(d: ObservableValue<*>)

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

open override fun addListener(listener: InvalidationListener)

addWeakChangeListener

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

addWeakListener

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

infix fun ObservableBoolean.and(other: ObservableBoolean): ObservableBoolean

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 equalTo(other: Boolean): ObservableBoolean

open fun equalTo(other: ObservableValue<Boolean>): ObservableBoolean

open override fun eval(): Boolean

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

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

fun <A> ObservableBoolean.ifElse(trueValue: A, falseValue: A): UnaryFunction<A, Boolean, ObservableBoolean>

open fun isNotNull(): ObservableBoolean

open fun isNull(): ObservableBoolean

operator fun ObservableBoolean.not(): ObservableBoolean

open fun notEqualTo(other: Boolean): ObservableBoolean

open fun notEqualTo(other: ObservableValue<Boolean>): ObservableBoolean

notSameInstance

open fun notSameInstance(other: Boolean): ObservableBoolean

open fun notSameInstance(other: ObservableValue<Boolean>): ObservableBoolean

infix fun ObservableBoolean.or(other: ObservableBoolean): ObservableBoolean

removeChangeListener

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

removeDependent

fun removeDependent(d: ObservableValue<*>)

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: Boolean): ObservableBoolean

open fun sameInstance(other: ObservableValue<Boolean>): ObservableBoolean

toObservableString

open fun toObservableString(): ObservableString

open fun toObservableString(nullString: String): ObservableString
