Sets up the internal layer object (ESRI) and initiates the loading process. The promise returned resolves when the object exists (i.e. .esriLayer is populated). This means the layer can be added to the map.

Initiates actions after layer load error. Should generally only be called internally by the RAMP core.
OptionalgenuineError: boolean = trueFlag to detect error setting due to manual cancellation. Only genuine errors will raise notifications.
Initiates actions after layer load. Should generally only be called internally by the RAMP core.
Attempts to reload the internal layer object (ESRI). Effectively doing a terminate then initiate, and removing/re-adding layer to the map.
If layer is map bound, and has an esri layer in the esri map, remove it from esri map. Typically should only be called by RAMP internals.
Baseline identify function for layers that do not support identify. Will return an empty result. Layers that support identify should override this method. Note: implementations that return real data must make that data reactive()
not used, present for nice signature of overrided function

DEPRECIATED #2595 Use setMaptipArcade
Resets the layer class to the state it was in "pre-initialize". Implementers can decide if they want to retain any state (e.g. UIDs/layerTree would be a good idea). Also an appropriate function to remove any event listeners/triggers. This would be called in situations like a layer getting deleted, or in a layer reload (initialize would be called again afterwards). Note this does not remove any layers from the map stack, that must be done by the caller.
Updates layer draw state and raises events. Should generally only be called internally by the RAMP core.
Updates layer layer state and raises events. Should generally only be called internally by the RAMP core.
Updates layer load state and raises events. Should generally only be called internally by the RAMP core.

Cause the map to zoom to this layer's boundary extent
resolves when map has finished zooming
Cause the map to zoom to a scale level where the layer is visible.
resolves when map has finished zooming
A base class for Layer subclasses. It provides some utility functions to Layer and also gives access to
$iApiand$vAppglobals. Mostly it exposes stub methods; this is because layer subclasses can be wildly different, so we don't have a pile of common things to put here. The stubs will help debugging as they will alert devs when they have not implemented something. The stubs also allow us to get intellisense / typescript happiness when dealing with common layer variables typed as LayerInstance.Export
