Create()

SysTable_Column * taco::SysTable_Column::Create ( const std::vector< Datum > &  data )

staticprivate

Creates a new SysTable_Column with a data vector read from some record payload.

This function is private and only accessible to the catalog cache implementation.

GetDatumVector()

std::vector< Datum > taco::SysTable_Column::GetDatumVector ( ) const

private

Returns all the fields as a datum vector.

Note that the entry itself must be kept alive when the datum vector is accessed, as we may return references without copying the underlying data. This function is private and only accessible to the catalog cache implementation.
