+#foo/**/qux
+# This matches foo/bar/qux, foo/baz/qux, and foo/bar/baz/qux
+
+# You can also negate patterns with an exclamation (!).

+# org.openapitools.client - Kotlin client library for Demo
+
+## Requires
+
+* Kotlin 1.4.30
+* Gradle 6.8.3
+
+## Build
+
+First, create the gradle wrapper script:
+
+```
+gradle wrapper
+```
+
+Then, run:
+
+```
+./gradlew check assemble
+```
+
+This runs all tests and packages the library.
+
+## Features/Implementation Notes
+
+* Supports JSON inputs/outputs, File inputs, and Form inputs.
+* Supports collection formats for query parameters: csv, tsv, ssv, pipes.
+* Some Kotlin and Java types are fully qualified to avoid conflicts with types defined in OpenAPI definitions.
+* Implementation of ApiClient is intended to reduce method counts, specifically to benefit Android targets.

+# org.openapitools.client - Kotlin client library for Demo
+
+
+A kotlin client for Android using the currently recommended http client, Volley. See https://developer.android.com/training/volley
+
+- Currently sends GsonRequests
+- Currently only supports Gson as a serializer - will throw an exception if a different serializer is chosen
+- Defaults the source location to src/main/java as per standard Android builds
+
+
+## Design
+
+Volley is a queue/request based layer on top of http url stack specific to Android. Android favours dependency injection and
+a layered architecture, and IO performed off the main thread to maintain UI responsiveness, with a preferred technique of
+kotlin co-routines. The code gen library reflects these factors.
+
+- Api calls use co-routines, and execute them using volley callbacks to avoid tying up a thread.
+- Facilitate dependency injection, with default implementations available.
+- Generate a requestFactory that can be overridden
+- Allow the passing of the RequestFactory per tag (api client) or per operation (an extra parameter is created on operations with non-global security), with per operation auth overriding global security.
+- DI scoping of the Request Factory and pre-generated auth header factories allow for thread safe and secure setting of credentials.
+- Lazy header factories allow for refreshing tokens etc
+- Factoring of header factories to the Request Factory allow ambient provision of credentials. Code gen library is credential storage agnostic.
+- Header factories allow the merging of generated headers from open api spec with dynamically added headers
+
+- Injection of http url stack to allow custom http stacks. Default implementation is best practice singleton
+- Data classes used for serialisation to reflect volley's preference - an immutable request that once queued can't be tampered with.
+
+- Reuse model class and other jvm common infrastructure
+
+- Optional generation of room database models, and transform methods to these from open api models
+- Room and api models can be extended with additional extension properties.
+
+## Future improvements
+- Option to generate image requests on certain conditionals e.g content-type gif etc
+- Support for kotlin serialization.
+- Multi part form parameters and support for file inputs
+
+## Usage
+Hilt Dependency injection example - with default values for parameters overridden.

+                postProcessors = listOf(retryPolicySetter)),
+            basePath = configurationService.getBaseUrl()
+        )
+    }
+```
+Here is the constructor so you can see the defaults
+```class SomeApi (
+val context: Context,
+val requestQueue: Lazy<RequestQueue> = lazy(initializer = {
+    Volley.newRequestQueue(context.applicationContext)
+    }),
+    val requestFactory: IRequestFactory = RequestFactory(),
+    val basePath: String = "https://yourbasepath.from_input_parameter.com/api",
+    private val postProcessors :List <(Request<*>) -> Unit> = listOf()) {
+```
+
+### Overriding defaults
+The above constructor for each api allows the following to be customized
+- A custom context, so either a singleton request queue or different scope can be created - see
+https://developer.android.com/training/volley/requestqueue#singleton
+- An overrideable request queue - which in turn can have a custom http url stack passed to it
+- An overrideable request factory constructor call, or a request factory that can be overridden by a custom template, with
+custom header factory, request post processors and custom gson adapters injected.
+
+#### Overriding request generation
+Request generation can be overridden by
+- Overriding the entire request factory template
+- Supplying custom header factories - methods that take any possible parameters but return a map of headers
+- Supplying custom request post processors - methods that take and return the request object
+
+Header factory examples can be found in the auth section, as these are implemented as header factories. eg
+```
+val basicAuthHeaderFactoryBuilder = { username: String?, password: String? ->
+{ mapOf("Authorization" to "Basic " + Base64.encodeToString("${username ?: ""}:${password ?: ""}".toByteArray(), Base64.DEFAULT))}
+}
+```
+In this case it's a lambda function (a factory method) that takes an username and password, and returns a map of headers. Other
+generated code will supply the username and password. In this case it results in a map of  just one key/value pair, but
+it could be multiple. The important part is it's returning a map - and that the surrounding code
+will can bind the inputs to it at some point.
+
+Here is a different example that supplies tracing header values
+```
+/**
+ * Create a lambda of tracing headers to be injected into an API's [RequestFactory].
+ */
+private fun createTraceHeaderFactory(): () -> Map<String, String> = {
+    mapOf(
+        HttpHeaderType.b3_traceId.rawValue to UUIDExtensions.asTraceId(UUID.randomUUID()),
+        HttpHeaderType.b3_spanId.rawValue to UUIDExtensions.asSpanId(UUID.randomUUID()),
+        HttpHeaderType.b3_sampled.rawValue to "1"
+    )
+}
+```
+Finally a post processor example
+```
+ /**
+     * Configure a [DefaultRetryPolicy] to be injected into the [RequestFactory] with a maximum number of retries of zero.
+     */
+    private val retryPolicySetter = { request: Request<*> ->
+        Unit.apply {
+            request.setRetryPolicy(
+                DefaultRetryPolicy(
+                    RestService.DEFAULT_TIMEOUT_MS,
+                    0,
+                    DefaultRetryPolicy.DEFAULT_BACKOFF_MULT
+                )
+            )
+        }
+    }
+```
+
+### Serialization
+#### Gson and Polymorphic types
+The GsonRequest object can be passed custom type adapters
+```
+class GsonRequest<T>(
+    method: Int,
+    url: String,
+    private val body: Any?,
+    private val headers: Map<String, String>?,
+    private val params: MutableMap<String, String>?,
+    private val contentTypeForBody: String?,
+    private val encodingForParams: String?,
+    private val gsonAdapters: Map<Type, Object>?,
+    private val type: Type,
+    private val listener: Response.Listener<T>,
+    errorListener: Response.ErrorListener
+) : Request<T>(method, url, errorListener) {
+
+    val gsonBuilder: GsonBuilder = GsonBuilder()
+        .registerTypeAdapter(OffsetDateTime::class.java, OffsetDateTimeAdapter())
+        .registerTypeAdapter(LocalDateTime::class.java, LocalDateTimeAdapter())
+        .registerTypeAdapter(LocalDate::class.java, LocalDateAdapter())
+        .registerTypeAdapter(ByteArray::class.java, ByteArrayAdapter())
+
+```
+## Requires
+
+* Kotlin 1.4.30
+* Gradle 6.8.3
+
+## Build
+
+First, create the gradle wrapper script:
+
+```
+gradle wrapper
+```
+
+Then, run:
+
+```
+./gradlew check assemble
+```
+
+This runs all tests and packages the library.
