Member Function Documentation

◆ clearRowBuffers()

virtual void pool::RootCollection::RootCollectionDataEditor::clearRowBuffers ( )

virtual

Clears all row buffers.

Should be applied before inserting rows for which some columns are expected to have null values.

Implements pool::ICollectionDataEditor.

◆ deleteRows()

virtual int pool::RootCollection::RootCollectionDataEditor::deleteRows	(	const std::string &	whereClause,
		coral::AttributeList *	attributeBindData = `0`,
		pool::TokenList *	tokenBindData = `0`,
		bool	updateRecordsCounter = `true`
	)

virtual

Deletes the rows of the collection that satisfy a query.

Returns the number of rows deleted. Throws an exception if no where clause is provided as input. An option is provided to turn off the written and deleted records counters if the written records counter was turned off during record insertion to improve performance.

Parameters

whereClause	Predicates of query.
attributeBindData	Attribute bind data for where clause.
tokenBindData	Token bind data for where clause.
updateRecordsCounter	Flag indicating whether to decrement written records counter and increment deleted records counter.

Implements pool::ICollectionDataEditor.

◆ emptyRowBuffer()

virtual CollectionRowBuffer& pool::RootCollection::RootCollectionDataEditor::emptyRowBuffer ( )

virtual

Returns a reference to an empty collection row buffer for adding rows of data to the collection.

If data will be provided for all columns use the method ‘rowBuffer’ instead since buffers do not need to be cleared in this case.

Implements pool::ICollectionDataEditor.

◆ insertRow()

virtual void pool::RootCollection::RootCollectionDataEditor::insertRow	(	const pool::CollectionRowBuffer &	inputRowBuffer,
		bool	updateRecordsCounter = `false`
	)

virtual

Adds a new row of data to the collection.

An option is provided to turn off the written records counter to improve performance.

Parameters

inputRowBuffer	Buffer containing data for row to be added.
updateRecordsCounter	Flag indicating whether to increment written records counter.

Implements pool::ICollectionDataEditor.

◆ rowBuffer()

virtual CollectionRowBuffer& pool::RootCollection::RootCollectionDataEditor::rowBuffer ( )

virtual

Returns a reference to a collection row buffer for adding rows of data to the collection.

If data for one or more columns will not be provided use the method ‘emptyRowBuffer’ instead.

Implements pool::ICollectionDataEditor.

◆ setRowCacheSize()

virtual void pool::RootCollection::RootCollectionDataEditor::setRowCacheSize ( int )

inlinevirtual

Sets the number of rows to cache before insertion into the collection.

If the input argument is 0 (the default) bulk row insertion will not be applied.

Parameters

rowCacheSize Number of rows to cache before insertion into collection.

Implements pool::ICollectionDataEditor.

◆ updateRows()

virtual int pool::RootCollection::RootCollectionDataEditor::updateRows	(	coral::AttributeList *	attributeSetList = `0`,
		TokenList *	tokenSetList = `0`,
		const std::string &	whereClause = `""`,
		coral::AttributeList *	attributeBindData = `0`,
		pool::TokenList *	tokenBindData = `0`
	)

virtual

Updates the rows of the collection that satisfy a query.

Returns the number of rows updated. Throws an exception if both the Attribute and Token set lists provided as input are empty.

Parameters

tokenSetList	List of Tokens to set with associated values.
attributeSetList	List of Attributes to set with associated values.
whereClause	Predicates of query.
attributeBindData	Attribute bind data for where clause.
tokenBindData	Token bind data for where clause.
