/**
|
|
* Replaces a component with a skinned version if a skinned version exists.
|
|
* This decorator should only be applied to components which can be skinned. For
|
|
* the react-sdk this means all components should be decorated with this.
|
|
*
|
|
* The decoration works by assuming the skin has been loaded prior to the
|
|
* decorator being called. If that's not the case, the developer will find
|
|
* out quickly through various amounts of errors and explosions.
|
|
*
|
|
* For a bit more detail on how this works, see docs/skinning.md
|
|
* @param {string} name The dot-path name of the component being replaced.
|
|
* @param {React.Component} origComponent The component that can be replaced
|
|
* with a skinned version. If no skinned version is available, this component
|
|
* will be used.
