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.

Run()

virtual void BulkLoader::Run ( ) throw ( sparksee::gdb::IOException, sparksee::gdb::Error )

virtual

Run the loader.

Exceptions

IOException	For errors accessing the file
Error	For other issues

SetAttributePositions()

void BulkLoader::SetAttributePositions

(

sparksee::gdb::Int32List &

attrsPos

)

Sets the list of attribute positions.

Parameters

attrsPos

[in] Attribute positions (column index >=0).

SetAttributes()

void BulkLoader::SetAttributes

(

sparksee::gdb::AttributeList &

attrs

)

Sets the list of Attributes.

Parameters

attrs

[in] Attribute identifiers to be loaded

SetFilename()

void BulkLoader::SetFilename

(

const std::wstring &

filename

)

Sets the input data source.

Parameters

rr	[in] Input RowReader.

References SetFilename().

Referenced by SetFilename().

SetLocale()

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.

SetLogError()

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.

SetTimestampFormat()

void BulkLoader::SetTimestampFormat

(

const std::wstring &

timestampFormat

)

Sets a specific timestamp format.

Parameters

timestampFormat

[in] A string with the timestamp format definition.

SetType()

void BulkLoader::SetType

(

sparksee::gdb::type_t

type

)

Sets the type to be loaded.

Parameters

type	[in] Type identifier.
