MunroQuery

Feature details

Munro Query it will help you to query and filter Munro Data.

Done:

• Domain layer with Data protocol that will be used to Query list.
• Empy Query
• Filter null munro from the list
• Sort by height
• Sort by name
• Filter by Hill type
• Filter by Min height
• Filter by Max height
• Limit results

Pre req:

• Can have 0 to all queries
• Order matters (makes sense from developer perspective)
• Error throw in case invalid query: repeat query, query with boundaries, incompatible queries (min and max shoudl not cross boundaries),etc.

Usage

First of all we need to create a Munro struct or class. This class will allow us to create a Builder query.

// Necessary step
struct Munro: MunroItemType {
    var gridReference: String
    var name: String
    var height: Double
    var category: MunroCategory?
}

Once we have it, we just need to create a query as follow.

// Example usage
func createQuery(listMunro: [Munro]) -> [Munro] {
    let munroQuery = try MunroQueryBuilder(for: listMunro)
        .minHeight(of: 200)
        .maxHeight(of: 450)
        .filterBy(.MUNRO)
        .sortByName(.ASC)
        .sortByHeight(.DES)
        .limitResults(to: 1)
        .build()
        
    return munroQuery.execute()
}
