…le GenAI Java SDK.
Automatic Function Calling (AFC) previously restricted function declarations and invocations to public static methods only, throwing an `IllegalArgumentException` ("Instance methods are not supported. Please use static methods.") if an instance method was provided. This forced users to encapsulate state in static fields or create static wrappers when calling methods on service objects.
Support passing an instance or instance mapping along with `Method` references when configuring tools for Automatic Function Calling:
- Remove static modifier validation in `FunctionDeclaration.fromMethod(...)` so schemas can be generated from instance methods.
- Add `function_instances` mapping field to `Tool` definition and builder overloads to `Tool.Builder`:
- `functions(Method, Object)`
- `functions(List<Method>, Object)`
- `functions(Map<Method, Object>)`
- Update `AfcUtil` to extract function instances from `GenerateContentConfig` and invoke target methods with their bound instance (`method.invoke(instance, args)`).
- Pass `functionInstanceMap` across synchronous and asynchronous model generation loops (`Models`, `AsyncModels`, `Chat`, and `AsyncChat`).
- Add unit tests in `FunctionDeclarationTest`, `AfcUtilTest`, and `PrivateChatAfcTest`.
Closes googleapis/java-genai#807
