function ViewExecutable::generateHandlerId

Generates a unique ID for a handler instance.

These handler instances are typically fields, filters, sort criteria, or arguments.

Parameters

string $requested_id: The requested ID for the handler instance.

array $existing_items: An array of existing handler instances, keyed by their IDs.

Return value

string A unique ID. This will be equal to $requested_id if no handler instance with that ID already exists. Otherwise, it will be appended with an integer to make it unique, e.g., "{$requested_id}_1", "{$requested_id}_2", etc.
