Member Function Documentation

dispose()

Wikibase\Repo\IO\EntityIdReader::dispose

(

)

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.

Implements Wikibase\DataModel\Services\EntityId\EntityIdPager.

getExceptionHandler()

Wikibase\Repo\IO\EntityIdReader::getExceptionHandler

(

)

Returns

ExceptionHandler

lineToId()

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

protected

Parameters

string

$line

Returns

EntityId|null

next()

Wikibase\Repo\IO\EntityIdReader::next ( )

protected

Returns the next ID (or null if there are no more ids).

Returns

EntityId|null

setExceptionHandler()

Wikibase\Repo\IO\EntityIdReader::setExceptionHandler
