Type Members

1. trait Broadcaster[A] extends Listenable[A]

   

   Implementation of Listener.

   Implementation of Listener. Subclasses can broadcast data of type A via the broadcast method.

2. class DefaultReusabilityOverlay extends ReusabilityOverlay with SetInterval

   

3. final class ExternalVar[A] extends AnyRef

   

   Provides a component with safe R/W access to an external variable.

   Provides a component with safe R/W access to an external variable.

   Use ReusableVar for a reusable version of this.

4. trait Listenable[A] extends AnyRef

   

   External entities can register with this to listen (receive) data of type A.

   External entities can register with this to listen (receive) data of type A.

   Install in ReactComponentB via .configure(Listenable.install...).

5. trait OnUnmount extends AnyRef

   

   Accrues procedures to be run automatically when its component unmounts.

   Accrues procedures to be run automatically when its component unmounts.

   Install in ReactComponentB via .configure(OnUnmount.install).

6. sealed abstract class Px[A] extends AnyRef

   

   A mechanism for caching data with dependencies.

   A mechanism for caching data with dependencies.

   This is basically a performance-focused, lightweight implementation of pull-based FRP, pull-based meaning that in the chain A→B→C, an update to A doesn't affect C until the value of C is requested.

   What does Px mean? I don't know, I just needed a name and I liked the way @lihaoyi's Rx type name looked in code. You can consider this "Performance eXtension". If this were Java it'd be named AutoRefreshOnRequestDependentCachedVariable.

7. implicit final class ReactExtrasAnyExt[A] extends AnyVal

   

   Annotations

   @inline()

8. final class Reusability[A] extends AnyVal

   

   Tests whether one instance can be used in place of another.

   Tests whether one instance can be used in place of another. Used mostly to compare properties and state of a component to avoid unnecessary updates.

   If you imagine a class with 8 fields, equality would compare all 8 fields where as this would typically just compare the ID field, the update-date, or the revision number. You might think of this as a very quick version of equality.

   Don't miss Reusability.shouldComponentUpdate which can be applied to a component via ReactComponentB.configure.

9. trait ReusabilityOverlay extends AnyRef

   

10. sealed abstract class ReusableFn[A, B] extends AbstractFunction1[A, B]

    

    A function that facilitates stability and reuse.

    A function that facilitates stability and reuse.

    In effective usage of React, callbacks are passed around as component properties. Due to the ease of function creation in Scala if it often the case that functions are created inline and thus provide no means of determining whether a component can safely skip its update. This class exists as a solution.

    0.9.0

11. class ReusableVal[A] extends AnyRef

    

    A value explicitly being marked as reusable.

    A value explicitly being marked as reusable.

    Usually reusability is determined by type (ie. via an implicit Reusability[A] available for an A). Instead, this type promises that reusability will be explicitly provided with each value.

12. class ReusableVal2[A, S] extends AnyRef

    

13. final class ReusableVar[A] extends AnyRef

    

    Reusable version of ExternalVar.

14. trait SetInterval extends OnUnmount

    

    Alternative to window.setInterval that automatically unregisters installed callbacks when its component unmounts.

    Alternative to window.setInterval that automatically unregisters installed callbacks when its component unmounts.

    Install in ReactComponentB via .configure(SetInterval.install).
