class QgsProviderSublayerTask : QgsTask
|
|
{
|
|
%Docstring(signature="appended")
|
|
A :py:class:`QgsTask` which retrieves sublayer details for a URI.
|
|
|
|
This task executes a call to
|
|
:py:func:`QgsProviderRegistry.querySublayers()` in a background thread.
|
|
Depending on the URI queried it can be expensive to calculate the
|
|
sublayers (e.g. in the case where a full table scan is required to
|
|
resolve mixed geometry type layers), so it is beneficial to perform
|
|
these queries in the background wherever possible.
|
|
|
|
While :py:func:`QgsProviderRegistry.querySublayers()` offers various
|
|
flags to control how in-depth the querying will be, these flags are not
|
|
exposed through :py:class:`QgsProviderSublayerTask`. Rather
|
|
:py:class:`QgsProviderSublayerTask` will always execute the most
|
|
thorough query possible, regardless of how expensive this may be.
