(

)

Closes the underlying input stream.

fetchIds()

Wikibase\Repo\IO\EntityIdReader::fetchIds

$limit

)

Fetches the next batch of IDs.

Calling this has the side effect of advancing the internal state of the page, typically implemented by some underlying resource such as a file pointer or a database connection.

Note

After some finite number of calls, this method should eventually return an empty list of IDs, indicating that no more IDs are available.

Parameters

int

$limit

The maximum number of IDs to return.

Returns

EntityId[] A list of EntityIds matching the given parameters. Will be empty if there are no more entities to list from the given offset.

getExceptionHandler()

Wikibase\Repo\IO\EntityIdReader::getExceptionHandler

(

)

Returns

ExceptionHandler

lineToId()

Wikibase\Repo\IO\EntityIdReader::lineToId (   $line )
