Member Function Documentation

Create()

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

staticprivate

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

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

funcid()

constexpr Oid taco::SysTable_Function::funcid ( ) const

inlineconstexpr

Returns the function ID.

funcid_colid()

static constexpr FieldId taco::SysTable_Function::funcid_colid ( )

inlinestaticconstexpr

funcname()

constexpr const std::string& taco::SysTable_Function::funcname ( ) const

inlineconstexpr

Returns the function name.

funcname_colid()

static constexpr FieldId taco::SysTable_Function::funcname_colid ( )

inlinestaticconstexpr

funcnargs()

constexpr int16_t taco::SysTable_Function::funcnargs ( ) const

inlineconstexpr

Returns the number of arguments.

funcnargs_colid()

static constexpr FieldId taco::SysTable_Function::funcnargs_colid ( )

inlinestaticconstexpr

funcrettypid()

constexpr Oid taco::SysTable_Function::funcrettypid ( ) const

inlineconstexpr

Returns the return type id.

If it is InvalidOid (0), this function does not have a return value (i.e., the return value is always NULL)..

funcrettypid_colid()

static constexpr FieldId taco::SysTable_Function::funcrettypid_colid ( )

inlinestaticconstexpr

GetDatumVector()

std::vector< Datum > taco::SysTable_Function::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.
