Member Function Documentation

castfuncid()

constexpr Oid taco::SysTable_Cast::castfuncid ( ) const

inlineconstexpr

Returns the function id of the cast.

castfuncid_colid()

static constexpr FieldId taco::SysTable_Cast::castfuncid_colid ( )

inlinestaticconstexpr

castisimplicit()

constexpr bool taco::SysTable_Cast::castisimplicit ( ) const

inlineconstexpr

Returns whether this cast can be implicit.

castisimplicit_colid()

static constexpr FieldId taco::SysTable_Cast::castisimplicit_colid ( )

inlinestaticconstexpr

castoprtypid()

constexpr Oid taco::SysTable_Cast::castoprtypid ( ) const

inlineconstexpr

Returns the type id of the operand.

castoprtypid_colid()

static constexpr FieldId taco::SysTable_Cast::castoprtypid_colid ( )

inlinestaticconstexpr

castrettypid()

constexpr Oid taco::SysTable_Cast::castrettypid ( ) const

inlineconstexpr

Returns the type id of the return value.

castrettypid_colid()

static constexpr FieldId taco::SysTable_Cast::castrettypid_colid ( )

inlinestaticconstexpr

Create()

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

staticprivate

Creates a new SysTable_Cast 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_Cast::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.
