Member Function Documentation

◆ copyValues() [1/2]

void te::mem::PreparedItemCopy::copyValues	(	const te::da::DataSetItem *	source,
		te::mem::DataSetItem *	destination,
		bool	copyGeometries = `true`
	)		const

Copies the values from the source dataSet item to the destination dataSet item by matching the column names. If a column from the source does not exist in the destination, it will not be copied.

◆ copyValues() [2/2]

void te::mem::PreparedItemCopy::copyValues	(	const te::da::DataSetItem *	source,
		te::mem::DataSetItem *	destination,
		const ColumnMapping &	vecColumnsMapping
	)		const

protected

Copies the values from the source dataSet item to the destination dataSet item using the given pre calculated vecColumnsMapping.

◆ prepareCopyValues()

ColumnMapping te::mem::PreparedItemCopy::prepareCopyValues	(	const te::da::DataSetItem *	source,
		te::mem::DataSetItem *	destination,
		bool	copyGeometries
	)		const

protected

Creates a list mapping the input columns to the output columns. This is used to optmize significantly when you need to copy several items with the same column order.

◆ reset()

void te::mem::PreparedItemCopy::reset ( )
