Methods

canHandle

canHandle(input: Operation): Promise<void>

Overrides OperationHandler.canHandle
- Defined in src/ldp/operations/HeadOperationHandler.ts:20
Checks if the input data can be handled by this class. Throws an error if it can't handle the data.

Parameters
- input: Operation
Returns Promise<void>

handle

handle(input: Operation): Promise<ResponseDescription>

Overrides OperationHandler.handle
- Defined in src/ldp/operations/HeadOperationHandler.ts:26
Handles the given input. This should only be done if the canHandle function returned true. Therefore, consider using the handleSafe function instead.

Parameters
- input: Operation
Returns Promise<ResponseDescription>

handleSafe

handleSafe(input: Operation): Promise<ResponseDescription>

Inherited from OperationHandler.handleSafe
- Defined in src/util/handlers/AsyncHandler.ts:35
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: Operation
  
  Input data that will be handled if it can be handled.
Returns Promise<ResponseDescription>

A promise resolving if the input can be handled, rejecting with an Error if not. Return value depends on the given type.
