Detailed Description

Some internal functions of catalog cache implementations.

This is a friend class of all SysTable_xxx structs so that it can provide access to members that are otherwise inaccessible.

Member Function Documentation

ConstructSysTableStruct()

template<class T , class ... Args>

static T* taco::CatCacheInternalAccess::ConstructSysTableStruct ( Args &&...  args )

inlinestaticprotected

Constructs a SysTable_xxx struct from c++ values by invoking its constructor.

CopySysTableStruct()

template<class T >

static T* taco::CatCacheInternalAccess::CopySysTableStruct ( const T *  s )

inlinestaticprotected

CreateSysTableStruct() [1/2]

template<class T >

static T* taco::CatCacheInternalAccess::CreateSysTableStruct ( const std::vector< Datum > &  data )

inlinestaticprotected

Creates a SysTable_xxx struct from a vector of data by invoking its Create() function.

This overload returns a plain pointer and the caller is responsible for managing the memory of the object, as the caller knows the exact type of the returned struct.

CreateSysTableStruct() [2/2]

std::shared_ptr< void > taco::CatCacheInternalAccess::CreateSysTableStruct ( Oid  tabid, const std::vector< Datum > &  data  )

staticprotected

Creates a SysTable_xxx struct for a row stored in a record payout in the specified table.

This overload returns an std::shared_ptr<void> which is an alias for an std::shared_ptr<SysTable_xxx> and will automatically destruct the object when there's no reference to the object.

The implementation of this function is automatically generated in catalog/CatCacheBase_gen.cpp.

GetDatumVector()

template<class T >

std::vector<Datum> taco::CatCacheInternalAccess::GetDatumVector ( const T &  systable_struct )
