Member Function Documentation

◆ Create()

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

staticprivate

Creates a new SysTable_Table 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_Table::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.

◆ operator=()

SysTable_Table& taco::SysTable_Table::operator= ( const SysTable_Table & )

privatedefault

◆ tabfid()

constexpr uint32_t taco::SysTable_Table::tabfid ( ) const

inlineconstexpr

Returns the file ID of the heap file of the table.

◆ tabfid_colid()

static constexpr FieldId taco::SysTable_Table::tabfid_colid ( )

inlinestaticconstexpr

◆ tabid()

constexpr Oid taco::SysTable_Table::tabid ( ) const

inlineconstexpr

Returns the table ID.

◆ tabid_colid()

static constexpr FieldId taco::SysTable_Table::tabid_colid ( )

inlinestaticconstexpr

◆ tabissys()

constexpr bool taco::SysTable_Table::tabissys ( ) const

inlineconstexpr

Returns whether this table is a catalog table.

◆ tabissys_colid()

static constexpr FieldId taco::SysTable_Table::tabissys_colid ( )

inlinestaticconstexpr

◆ tabisvarlen()

constexpr bool taco::SysTable_Table::tabisvarlen ( ) const
