Protected viewThe instance of Vue R4MP application controlled by this InstanceAPI.
This is just a shorthand for this.$iApi.$vApp.
APIScope
Indicates if the layer is in a state that is makes sense to interact with. I.e. False if layer has not done it's initial load, or is in error state. Acts as a handy shortcut to inspecting the layerState.
true if layer is loaded
isLoaded
Indicates if the Esri map layer exists

Protected configProcesses any layer order configuration and modifies the passed ESRI layer config with ESRI-friendly definitions
{RampLayerConfig} Ramp layer configuration object.
Check if layer controls is available on this layer.
the layer control to check
Indicates if the given control is enabled on this layer
Invokes the process to get the full set of attribute values for the layer. Repeat calls will re-use the downloaded values unless the values have been explicitly cleared.
resolves with set of attribute values
Returns a SQL WHERE condition that is combination of active filters.
Optional exclusions: string[]list of any filter keys to exclude from the result. omission includes all filters
all non-excluded sql statements connected with AND operators.
getCombinedSqlFilter
Gets array of object ids that currently pass any filters
Optional exclusions: string[] = []list of any filters keys to exclude from the result. omission includes all filters
Optional extent: Extent = undefinedif provided, the result list will only include features intersecting the extent
resolves with array of object ids that pass the filter. if no filters are active, resolves with undefined.
getFilterOIDs
Fetches a graphic from the given layer. This overrides the baseclass method, as we are all local and dont need quick caches or server hits
ID of object being searched for
object containing option parametrs - map map wrapper object of current map. only required if requesting geometry - getGeom boolean. indicates if return value should have geometry included. default to false - getAttribs boolean. indicates if return value should have attributes included. default to false
resolves with a Graphic
getGraphic
Gets the extent where the provided object id is on the map. Can only be used on feature layers with multipoint, polyline, polygon geometry.
the object id to query
resolves with the extent where the object id is present
Provides the spatial reference of the layer
the layer spatial reference in RAMP API format
Private getPrivate
Attempts to get an sublayer based on the index or uid provided.
the uid or numeric index of the item we are interested in
the matching feature class object, or undefined if the root was requested
Invokes the process to get the full set of attribute values for the layer, formatted in a tabular format. Additional data properties are also included. Repeat calls will re-use the downloaded values unless the values have been explicitly cleared.
resolves with set of tabular attribute values
Indicates if the layer is not in a visible scale range.
Optional testScale: number = undefinedoptional scale to test against. if not provided, current map scale is used.
true if the layer is outside of a visible scale range
isOffscale
Will load and apply metadata from the ArcGIS Server endpoint to this layer.

Each result item is loaded independently. This will capitalize on caching, but will be expensive when expecting a large result set and nothing currently cached.

Will return an array of object ids for features in the layer that satisfy the conditions of the query options parameter.

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()

setCustomParameter
Applies an SQL filter to the layer. Will overwrite any existing filter for the given key.
Use 1=2 for a "hide all" where clause.

the WHERE clause of the filter
Protected startProtected stopProtected stubResets 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.
