Member Function Documentation

sparksee::gdb::bool_t TypeExporter::CanRun ( )

protectedinherited

Checks that all the required settings are ready to run.

Returns: Returns true if all the settings are ready.

void TypeExporter::NotifyListeners ( const TypeExporterEvent & ev )

protectedinherited

Notifies progress to all registered listeners.

Parameters

ev	[in] Progress event to be notified.

void TypeExporter::Register ( TypeExporterListener & tel )

inherited

Registers a new listener.

Parameters

tel	[in] TypeExporterListener to be registered.

void TypeExporter::RunProcess	(		)
throw	(	sparksee::gdb::IOException,
		sparksee::gdb::Error
	)

protectedinherited

Runs export process.

Exceptions

IOException If bad things happen writting to the RowWriter.

void TypeExporter::SetAttributes ( sparksee::gdb::AttributeList & attrs )

inherited

Sets the list of Attributes.

Parameters

attrs [in] Attribute identifiers to be exported

void TypeExporter::SetFrequency ( sparksee::gdb::int32_t freq )

inherited

Sets the frequency of listener notification.

Parameters

freq	[in] Frequency in number of rows managed to notify progress to all listeners

void TypeExporter::SetGraph ( sparksee::gdb::Graph & graph )

inherited

Sets the graph that will be exported.

Parameters

graph [in] Graph.

void TypeExporter::SetHeadAttribute ( sparksee::gdb::attr_t attr )

protectedinherited

Sets the attribute that will be used to get the value to be dumped for the head of the edge.

This method is protected because only the Edge exporters should have it.

Parameters

attr	[in] Head Attribute

Referenced by EdgeTypeExporter::EdgeTypeExporter(), and EdgeTypeExporter::SetHeadAttribute().

void TypeExporter::SetHeader ( sparksee::gdb::bool_t header )

inherited

Sets the presence of a header row.

Parameters

header [in] If TRUE, a header row is dumped with the name of the attributes.

void TypeExporter::SetHeadPosition ( sparksee::gdb::int32_t pos )

protectedinherited

Sets the position (index column) of the head attribute in the exported data.

This method is protected because only the Edge exporters should have it.

Parameters

pos	[in] Head position

Referenced by EdgeTypeExporter::EdgeTypeExporter(), and EdgeTypeExporter::SetHeadPosition().

void TypeExporter::SetRowWriter ( RowWriter & rw )

inherited

Sets the output data destination.

Parameters

rw	[in] Input RowWriter.

void TypeExporter::SetTailAttribute ( sparksee::gdb::attr_t attr )

protectedinherited

Sets the attribute that will be used to get the value to be dumped for the tail of the edge.

This method is protected because only the Edge exporters should have it.

Parameters

attr	[in] Tail Attribute

Referenced by EdgeTypeExporter::EdgeTypeExporter(), and EdgeTypeExporter::SetTailAttribute().

void TypeExporter::SetTailPosition ( sparksee::gdb::int32_t pos )

protectedinherited

Sets the position (index column) of the tail attribute in the exported data.

This method is protected because only the Edge exporters should have it.

Parameters

pos	[in] Tail position

Referenced by EdgeTypeExporter::EdgeTypeExporter(), and EdgeTypeExporter::SetTailPosition().

void TypeExporter::SetType ( sparksee::gdb::type_t type )

inherited

Sets the type to be exported.

Parameters

type	[in] Type identifier.
