Class ZCX_LLM_VALIDATION

AI Generated documentation.

Overview

ZCX_LLM_VALIDATION is an exception class inheriting from CX_DYNAMIC_CHECK that handles various validation and error scenarios in an LLM (Large Language Model) client implementation. The class provides structured exception handling with predefined message types for:

  • Type validation (UNSUPPORTED_TYPE)
  • Value range validation (VALUE_OUT_OF_RANGE)
  • Model existence checks (MODEL_DOES_NOT_EXIST, CLIENT_MODEL_NOT_FOUND)
  • HTTP communication issues (HTTP_DESTINATION_ERROR)
  • Encryption/Decryption handling (ENCRYPTION_SETUP, ENCRYPTION_FAILED, DECRYPTION_FAILED)
  • Provider validation (PROVIDER_DOES_NOT_EXIST)

Each exception type can carry up to 4 attributes (MV_ATTR1 to MV_ATTR4) for detailed error information.

Public methods:

  • CONSTRUCTOR: Creates exception instance with message ID and optional attributes

Dependencies

  • Inherits from CX_DYNAMIC_CHECK
  • Implements IF_T100_MESSAGE
  • Uses message class ZLLM_CLIENT

Details

The class follows the SAP standard exception handling pattern with T100 messages. All message definitions are bound to the custom message class ZLLM_CLIENT.

Exception flow:

graph TD
    A[Application Code] -->|Raises| B[ZCX_LLM_VALIDATION]
    B -->|Contains| C[Message Key]
    B -->|Contains| D[Attributes 1-4]
    C -->|References| E[ZLLM_CLIENT Messages]

The exception handling is designed to provide detailed error information through a combination of:

  • Predefined message IDs (msgid: ZLLM_CLIENT)
  • Message numbers (msgno)
  • Up to 4 dynamic attributes that can be referenced in the message text
  • Previous exception handling for error chaining

The class is marked as FINAL to prevent inheritance, ensuring consistent error handling across the LLM client implementation.
