GIS - TryCreateForInput

Hi,

1.I used GIS API .

2.There are 15 formats:

EsriJson GeoJson GeoJsonSeq Kml/Kmz Shapefile OsmXml Gpx Gml FileGdb TopoJson MapInfoInterchange MapInfoTab Csv GeoPackage.

3.This is my main function: TryCreateForInput that gisInputFilePath-Path to a single GIS file or archive to inspect and returns IConverterFactory + detectReason-uman friendly reason describing how the converter was selected (useful for logging).

Since it critical in my app and difficult to hanle all cases , please can you look on the code

if it a good practice. If not can you make the fixes, the class not depend on other classes.

4.The summary of main function:

    /// <summary>

    /// Inspect the input path (file or archive) and attempt to resolve a converter from the factory.

    /// </summary>

    /// <param name="factory">Factory used to resolve a converter key to an <see cref="IConverter"/> instance.</param>

    /// <param name="gisInputFilePath">Path to a single GIS file or archive to inspect.</param>

    /// <param name="converter">Out parameter populated with the resolved converter when the method returns true.</param>

    /// <param name="detectReason">Human friendly reason describing how the converter was selected (useful for logging).</param>

    /// <returns>True when a converter was resolved; false when detection failed or result was ambiguous.</returns>

    /// <remarks>

    /// Behaviour details

    /// - Returns false and sets <paramref name="detectReason"/> when:

    ///   - The input path is invalid or cannot be inspected.

    ///   - Archive inspection is ambiguous (for example tied JSON votes).

    ///   - No matching converter mapping or requirement rules are found.

    /// - Detection steps (high-level):

    ///   1. If the input looks like an archive (see <see cref="ConverterUtils.IsArchiveFile"/>):

    ///      a. Use <see cref="ConverterUtils.TryListArchiveEntries"/> to obtain entry names (no extraction).

    ///      b. Build a set of discovered extensions / markers and apply fast "wins" (explicit .geojson/.esrijson).

    ///      c. Apply the KMZ guard (outer .kmz or top-level doc.kml => Kmz).

    ///      d. If archive contains only generic .json entries, open each .json entry and perform bounded header reads

    ///         (see <c>ReadEntryHeadUtf8</c>) and classify via <c>ClassifyJsonHeader</c>; then apply majority voting.

    ///      e. Otherwise apply strict requirement matching against <see cref="_s_archiveRequirements"/>.

    ///   2. For single-file inputs:

    ///      a. Use explicit extension mapping for .geojson and .esrijson.

    ///      b. For generic .json files invoke <c>JsonFormatDetector.DetectFromFile</c> (if available) then fall back

    ///         to a bounded header read + <c>ClassifyJsonHeader</c>.

    ///      c. Map the detected JSON format to a converter key (GeoJson / EsriJson / GeoJsonSeq / TopoJson).

    ///

    /// Safety and IO

    /// - This method avoids extracting archive contents. When entry-stream reads are required they are bounded

    ///   to <c>HeaderReadLimit</c> bytes and performed via streaming to minimize memory usage.

    /// - Unexpected exceptions are caught; the method logs details and returns false with a detect reason describing the problem.

    /// </remarks>
