~QgsPointCloudBlockRequest()

virtual QgsPointCloudBlockRequest::~QgsPointCloudBlockRequest ( )

pure virtual

Member Function Documentation

errorStr()

QString QgsPointCloudBlockRequest::errorStr

(

)

Returns the error message string of the request.

finished

void QgsPointCloudBlockRequest::finished ( )

signal

Emitted when the request processing has finished.

takeBlock()

std::unique_ptr< QgsPointCloudBlock > QgsPointCloudBlockRequest::takeBlock

(

)

Returns the requested block.

if the returned block is nullptr, that means the data request failed.
