Member Function Documentation

Create()

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

staticprivate

Creates a new SysTable_Operator 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_Operator::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.

oparg0typid()

constexpr Oid taco::SysTable_Operator::oparg0typid ( ) const

inlineconstexpr

Returns the type id of the operand 0.

oparg0typid_colid()

static constexpr FieldId taco::SysTable_Operator::oparg0typid_colid ( )

inlinestaticconstexpr

oparg1typid()

constexpr Oid taco::SysTable_Operator::oparg1typid ( ) const

inlineconstexpr

Returns the type id of the operand 1.

oparg1typid_colid()

static constexpr FieldId taco::SysTable_Operator::oparg1typid_colid ( )

inlinestaticconstexpr

operator=()

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

privatedefault

opfuncid()

constexpr Oid taco::SysTable_Operator::opfuncid ( ) const

inlineconstexpr

Returns the function ID.

opfuncid_colid()

static constexpr FieldId taco::SysTable_Operator::opfuncid_colid ( )

inlinestaticconstexpr

optype()

constexpr uint8_t taco::SysTable_Operator::optype ( ) const

inlineconstexpr

Returns the type of the operator, see expr/optypes.h.
