fun interface Interceptor

Intercepts network requests to observe, modify or short-circuit requests and their corresponding responses. Typical use cases for interceptors are network request logging, request mocking (for test implementations) or adding/removing/transforming headers on the request.

An interceptor is created and configured by creating a new ArcGISHttpClient and setting this new instance on ArcGISEnvironment using ArcGISEnvironment.configureArcGISHttpClient.

The following example shows how to configure an interceptor that adds a custom header to every network request:

ArcGISEnvironment.configureArcGISHttpClient {
interceptor { chain ->
val request = chain.request()
val modifiedRequest = request.newBuilder()
.addHeader(customHeaderName, customHeaderValue)
