Interface MimeTypeResolver

Functional Interface:

This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.

@FunctionalInterface
public interface MimeTypeResolver

Resolves a file path to an HTTP Content-Type value.

Implementations used with StaticFiles must be thread-safe; StaticFiles invokes resolvers concurrently from request-handling threads.

StaticFiles' default resolver uses a curated deterministic extension map for common web assets. It does not call Files.probeContentType(Path). A custom resolver fully replaces that default, and Optional.empty() means no Content-Type header is emitted.

Method Summary

Modifier and Type	Method	Description
@NonNull Optional<String>	contentTypeFor(@NonNull Path path)	Resolves the Content-Type for path.
static @NonNull MimeTypeResolver	defaultInstance()	Acquires Soklet's default threadsafe MimeTypeResolver.

Method Details

contentTypeFor

@NonNull Optional<String> contentTypeFor(@NonNull Path path)

Resolves the Content-Type for path.

When configured through StaticFiles.Builder.mimeTypeResolver(MimeTypeResolver), this resolver fully replaces the default resolver. To extend Soklet's default extension map, delegate to defaultInstance() for paths your implementation does not handle.

Parameters:

path - the resolved file path being served

Returns:

the content type to emit, or Optional.empty() to omit it

defaultInstance

static @NonNull MimeTypeResolver defaultInstance()

Acquires Soklet's default threadsafe MimeTypeResolver.

The default resolver uses a curated deterministic extension map for common web assets and returns Optional.empty() for unknown extensions.

Returns:

the default MimeTypeResolver
