Detailed Description
NodeTypeLoader class.
Specific TypeLoader implementation for node types.
Check out the 'Data import' section in the SPARKSEE User Manual for more details on this.
Method Documentation
| - (id) initWithRowReader: | (STSRowReader *) | rowReader | |
| graph: | (STSGraph *) | graph | |
| type: | (int) | type | |
| attrs: | (STSAttributeList *) | attrs | |
| attrsPos: | (STSInt32List *) | attrsPos | |
Creates a new instance.
- Parameters
-
rowReader [in] Input RowReader. graph [in] Graph. type [in] Type identifier. attrs [in] Attribute identifiers to be loaded. attrsPos [in] Attribute positions (column index >=0).
| - (void) registerListener: | (STSTypeLoaderListener *) | tel |
Registers a new listener.
- Parameters
-
tel TypeLoaderListener to be registered.
| - (void) run |
See the TypeLoader class Run method.
- Exceptions
-
System.ApplicationException null System.IO.IOException null
Implements STSTypeLoader.
| - (void) runNPhases: | (int) | partitions |
See the TypeLoader class RunNPhases method.
- Parameters
-
partitions null
- Exceptions
-
System.ApplicationException null System.IO.IOException null
Implements STSTypeLoader.
| - (void) runTwoPhases |
See the TypeLoader class RunTwoPhases method.
- Exceptions
-
System.ApplicationException null System.IO.IOException null
Implements STSTypeLoader.
| - (void) setAttributePositions: | (STSInt32List *) | attrsPos |
Sets the list of attribute positions.
- Parameters
-
attrsPos [in] Attribute positions (column index >=0).
| - (void) setAttributes: | (STSAttributeList *) | attrs |
Sets the list of Attributes.
- Parameters
-
attrs [in] Attribute identifiers to be loaded
| - (void) setFrequency: | (int) | freq |
Sets the frequency of listener notification.
- Parameters
-
freq [in] Frequency in number of rows managed to notify progress to all listeners
| - (void) setGraph: | (STSGraph *) | graph |
Sets the graph where the data will be loaded.
- Parameters
-
graph [in] Graph.
| - (void) setLocale: | (NSString *) | 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) setLogError: | (NSString *) | path |
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
-
System.IO.IOException If bad things happen opening the file.
| - (void) setLogOff |
Truns off all the error reporting.
The log file will not be created and no exceptions for invalid data will be thrown. If you just want to turn off the logs, but abort at the first error what you should do is not call this method and not set a logError file.
| - (void) setRowReader: | (STSRowReader *) | rr |
Sets the input data source.
- Parameters
-
rr [in] Input RowReader.
| - (void) setTimestampFormat: | (NSString *) | timestampFormat |
Sets a specific timestamp format.
- Parameters
-
timestampFormat [in] A string with the timestamp format definition.
| - (void) setType: | (int) | type |
Sets the type to be loaded.
- Parameters
-
type [in] Type identifier.
