pure virtual

Member Function Documentation

◆ block()

QgsPointCloudBlock* QgsPointCloudBlockRequest::block ( )

Returns the requested block.

if the returned block is nullptr, that means the data request failed Note: It is the responsablitiy of the caller to delete the block if it was loaded correctly
