new LayerRecord(layerClass, apiRef, config, esriLayer, epsgLookup)
- Source:
Create a layer record with the appropriate geoApi layer type. Layer config should be fully merged with all layer options defined (i.e. this constructor will not apply any defaults).
Parameters:
| Name | Type | Description |
|---|---|---|

validateProjection(spatialReference) → {Boolean}

Parameters:
| Name | Type | Description |
|---|---|---|
spatialReference |
Object | spatial reference to compare against. |
Returns:
true if layer has same sr as input. false otherwise.
