Interface InputValue<T>

Input Value

Input values directly access properties data from the feature.

ex.

Lets say you have a feature with the following properties:

const properties = {
  class: {
    type: 'blue',
    subclass: 'deep'
  }
}

You can utilize/access the type property with the following:

{
  "color": {
     "inputValue": {
        "key": {
           "nestedKey": ["class", "type"],
        },
        "fallback": "blue"
     }
  }
}

key: [See NestedKey] Access value in feature properties by either its key or a nested key.
fallback: If the property search for a key turns up no value, the fallback is used.

interface InputValue<T extends NotNullOrObject> {
fallback: T;
key: string | NestedKey;
}

fallback: T

If the property search for a key turns up no value, the fallback is used.

key: string | NestedKey

Access value in feature properties by either its key or a nested key.

If the key is class for example, this would be used to filter feature's values where feature.properties.class === 'ocean'

nested conditions are used to dive into nested properties

ex.

{ "filter": { "key": { "nestedKey": ["class", "type"] }, "comparator": "==", "value": "ocean" } }

this would be used to filter features where feature.properties.class.type === 'ocean'
