Detailed Description
Base TypeLoader class.
Base class to load a node or edge type from a graph using a RowReader.
TypeLoaderListener can be registered to receive information about the progress of the load process by means of TypeLoaderEvent. The default frequency of notification to listeners is 100000.
Check out the 'Data import' section in the SPARKSEE User Manual for more details on this.
Member Function Documentation
| void BulkLoader::SetAttributePositions | ( | sparksee::gdb::Int32List & | attrsPos | ) |
Sets the list of attribute positions.
- Parameters
-
attrsPos [in] Attribute positions (column index >=0).
| void BulkLoader::SetAttributes | ( | sparksee::gdb::AttributeList & | attrs | ) |
Sets the list of Attributes.
- Parameters
-
attrs [in] Attribute identifiers to be loaded
| void BulkLoader::SetFilename | ( | const std::wstring & | filename | ) |
Sets the input data source.
- Parameters
-
rr [in] Input RowReader.
| void BulkLoader::SetLocale | ( | const std::wstring & | localeStr | ) |
Sets the locale that will be used to read the data.
It should match the locale used in the rowreader.
- Parameters
-
localeStr [in] The locale string for the read data. See CSVReader.
| void BulkLoader::SetLogError | ( | const std::wstring & | path | ) | |
| throw | ( | sparksee::gdb::IOException | |||
| ) | |||||
Sets a log error file.
By default errors are thrown as a exception and the load process ends. If a log file is set, errors are logged there and the load process does not stop.
- Parameters
-
path [in] The path to the error log file.
- Exceptions
-
IOException If bad things happen opening the file.
| void BulkLoader::SetTimestampFormat | ( | const std::wstring & | timestampFormat | ) |
Sets a specific timestamp format.
- Parameters
-
timestampFormat [in] A string with the timestamp format definition.
| void BulkLoader::SetType | ( | sparksee::gdb::type_t | type | ) |
Sets the type to be loaded.
- Parameters
-
type [in] Type identifier.
