◆ getText()

TextPassDumper::getText (   $id,
  $model = null,
  $format = null 
)

Tries to get the revision text for a revision id.

Export transformations are applied if the content model can is given or can be determined from the database.

Upon errors, retries (Up to $this->maxFailures tries each call). If still no good revision get could be found even after this retrying, "" is returned. If no good revision text could be returned for $this->maxConsecutiveFailedTextRetrievals consecutive calls to getText, MWException is thrown.

Parameters
string$idThe revision id to get the text for
string | bool | null$modelThe content model used to determine applicable export transformations. If $model is null, it will be determined from the database.
string | null$formatThe content format used when applying export transformations.
Exceptions
MWException
Returns
string The revision text for $id, or ""
