Class ZCL_LLM_CLIENT_BASE

AI Generated documentation.

Overview

zcl_llm_client_base is an abstract base class for implementing Large Language Model (LLM) clients across different providers. It provides a standardized framework for:

  • Creating chat requests
  • Handling HTTP communication
  • Processing LLM responses
  • Managing tool calls and structured outputs

Key public methods:

  • chat(): Sends a chat request to the LLM provider
  • new_request(): Creates a new chat request with default configurations
  • get_client(): Retrieves a provider-specific client implementation

Dependencies

  • zif_llm_client: Main client interface
  • zif_llm_http_client_wrapper: HTTP communication wrapper
  • zif_llm_tool_parser: Tool parameter parsing
  • zif_llm_statistics: Statistics tracking

Details

The class implements a flexible and extensible architecture for LLM interactions with several key design aspects:

classDiagram
    class zcl_llm_client_base {
        +zif_llm_client~chat()
        +zif_llm_client~new_request()
        #build_request_json()
        #handle_http_response()
        #handle_tool_calls()
    }
    note for zcl_llm_client_base "Abstract base class\nProvides core LLM client functionality"

Key architectural patterns:

  • Abstract methods for provider-specific implementations
  • Standardized response and request handling
  • Flexible tool call and structured output processing
  • Configurable via client and provider configurations

Request processing flow:

  1. Create request via new_request()
  2. Configure request parameters
  3. Call chat() method
  4. Internal methods handle:
  5. JSON request building
  6. HTTP communication
  7. Response parsing
  8. Tool call processing

The class supports:

  • Multiple LLM providers
  • Structured output generation
  • Tool call execution
  • Detailed usage statistics tracking

Extensibility is achieved through abstract methods like get_chat_endpoint(), set_auth(), allowing provider-specific implementations while maintaining a consistent interface.
