Class RnException<ErrObj>

Custom exception class for Rhodonite framework errors. This class extends the standard Error class to provide enhanced error handling with structured error information from RnError objects.

Example

const rnError: RnError<string> = {
  message: "Operation failed",
  error: "Invalid parameter"
};
const exception = new RnException(rnError);
throw exception;

Constructors

constructor

  • new RnException<ErrObj>(err): RnException<ErrObj>

  • Creates a new RnException instance.

    Type Parameters

    • ErrObj

    Parameters

    • err: RnError<ErrObj>

      The RnError object containing the error message and details

    Returns RnException<ErrObj>

    Remarks

    The constructor automatically formats the error message to include both the message and error details. If the error object contains a nested RnException, it will display "see below Exception ↓" followed by the nested exception's string representation.

Properties

Static Readonly_prefix

_prefix: "\nRhodonite Exception" = '\nRhodonite Exception'

Prefix string used in the exception name to identify Rhodonite exceptions

Methods

getRnError

  • getRnError(): RnError<ErrObj>

  • Retrieves the original RnError object that was used to create this exception.

    Returns RnError<ErrObj>

    The RnError object containing the original error message and details

    Example

    try {
      // some operation that throws RnException
    } catch (error) {
      if (error instanceof RnException) {
        const originalError = error.getRnError();
        console.log(originalError.message);
      }
    }
