Methods

canHandle

canHandle(input: ErrorHandlerArgs): Promise<void>

Overrides ErrorHandler.canHandle
- Defined in src/ldp/http/ConvertingErrorHandler.ts:36
Checks if the input data can be handled by this class. Throws an error if it can't handle the data.

Parameters
- input: ErrorHandlerArgs
Returns Promise<void>

Private createResponse

createResponse(statusCode: number, converted: Representation): ResponseDescription

- Defined in src/ldp/http/ConvertingErrorHandler.ts:71
Creates a ResponseDescription based on the Representation.

Parameters
- statusCode: number
- converted: Representation
Returns ResponseDescription

handle

handle(input: ErrorHandlerArgs): Promise<ResponseDescription>

Overrides ErrorHandler.handle
- Defined in src/ldp/http/ConvertingErrorHandler.ts:42
Handles the given input. This should only be done if the canHandle function returned true. Therefore, consider using the handleSafe function instead.

Parameters
- input: ErrorHandlerArgs
Returns Promise<ResponseDescription>

handleSafe

handleSafe(input: ErrorHandlerArgs): Promise<ResponseDescription>

Overrides ErrorHandler.handleSafe
- Defined in src/ldp/http/ConvertingErrorHandler.ts:50
Helper function that first runs the canHandle function followed by the handle function. Throws the error of the canHandle function if the data can't be handled, or returns the result of the handle function otherwise.

Parameters
- input: ErrorHandlerArgs
Returns Promise<ResponseDescription>

Private prepareArguments

prepareArguments(__namedParameters: ErrorHandlerArgs): PreparedArguments

- Defined in src/ldp/http/ConvertingErrorHandler.ts:61
Prepares the arguments used by all functions.

Parameters
- __namedParameters: ErrorHandlerArgs
Returns PreparedArguments

Private toRepresentation

toRepresentation(error: Error, statusCode: number): Representation

- Defined in src/ldp/http/ConvertingErrorHandler.ts:84
Creates a Representation based on the given error. Content type will be internal/error. The status code is used for metadata.

Parameters
- error: Error
- statusCode: number
Returns Representation
