Contains models for the Data Protocols. Install this if you want to implement an Protocol service yourself. Installation is via nuget, PM> Install-Package ADP.Models

Filtering

This Adp1Filter supports the following filtering options:

Geographical filters (for geometry parameters)

• AddGeoDistanceFilter(string parameterName, double lat, double lon, double distance)
• AddGeoPolygonFilter(string parameterName, string polygonWkt)

Comparison filters (for integers and dates)

• AddGreaterThanFilter<T>(string parameterName, T greaterThan)
• AddGreaterThanOrEqualFilter<T>(string parameterName, T greaterThanOrEqualTo)
• AddLessThanFilter<T>(string parameterName, T lessThan)
• AddLessThanOrEqualFilter<T>(string parameterName, T lessThanOrEqualTo)
• AddLessThanFilter<T>(string parameterName, T lessThan)
• AddMatchFilter<T>(string parameterName, params T[] acceptableValues)
• AddNotMatchFilter<T>(string parameterName, params T[] unacceptableValues)
• AddRangeFilter<T>(string parameterName, T greaterThan, T lessThan)

String filters

• AddStringContainsFilter(string parameterName, params string[] substrings)
• AddStringNotContainsFilter(string parameterName, params string[] substrings)
• AddStringEndsWithFilter(string parameterName, params string[] startsWith)
• AddStringIsSubstringOfFilter(string parameterName, string superstring)
• AddStringStartsWithFilter(string parameterName, params string[] startsWith)

Equality filters (for all types of fields)

• AddMatchFilter<T>(string parameterName, params T[] acceptableValues)
• AddNotMatchFilter<T>(string parameterName, params T[] unacceptableValues);

Adding your own filter

All the filter functions above internally use the AddFilter<T> function.

For service-specific filters, you can use the AddFilter function yourself, or add it as an extention method to the Adp1Filter:

public static class BlackboxExtentions
    {
        /// <summary>
        /// Filter for geometric fields - find all geometries that intersect with the given WKT
        /// </summary>
        /// <param name="parameterName">The name of the field in the entities</param>
        /// <param name="polygonWkt">The WKT of the bounding/intersecting polygon</param>
        public static void AddGeoIntersectFilter(this Adp1Filter filter, string parameterName, string polygonWkt)
        {
            filter.complex_operators.AddFilter(parameterName, "geo_intersect", polygonWkt);
        }
    }

We can then build our filter as normal:

    Adp1Filter filter = new Adp1Filter();
    filter.AddMatchFilter("ENTITY_TYPE", "Pikacho");
    filter.AddGeoIntersectFilter("geo", "POLYGON ((30 30,30 35,35 35, 35 30, 30 30))");
