Functions

addFileExtensionResolvers	`open fun addFileExtensionResolvers(vararg resolvers: MediaTypeFileExtensionResolver): Unit` Register more `MediaTypeFileExtensionResolver` instances in addition to those detected at construction.
getAllFileExtensions	`open fun getAllFileExtensions(): MutableList<String>` {@inheritDoc} At startup this method returns extensions explicitly registered with either PathExtensionContentNegotiationStrategy or ParameterContentNegotiationStrategy. At runtime if there is a "path extension" strategy and its `useRegisteredExtensionsOnly` property is set to "false", the list of extensions may increase as file extensions are resolved via org.springframework.http.MediaTypeFactory and cached.
getStrategies	`open fun getStrategies(): MutableList<ContentNegotiationStrategy>` Return the configured content negotiation strategies.
getStrategy	`open fun <T : ContentNegotiationStrategy> getStrategy(strategyType: Class<T>): T` Find a `ContentNegotiationStrategy` of the given type.
resolveFileExtensions	`open fun resolveFileExtensions(mediaType: MediaType): MutableList<String>`
resolveMediaTypes	`open fun resolveMediaTypes(request: NativeWebRequest): MutableList<MediaType>`
