    MongoDB\Driver\CursorInterface::isDead — Checks if the cursor may have additional results

    Опис

    abstract public MongoDB\Driver\CursorInterface::isDead(): bool

    Checks whether the cursor may have additional results available to read. A cursor is initially "alive" but may become "dead" for any of the following reasons:

    • Advancing a non-tailable cursor did not return a document
    • The cursor encountered an error
    • The cursor read its last batch to completion
    • The cursor reached its configured limit
    This is primarily useful with tailable cursors.
