Member Function Documentation

Create() [1/2]

TableDesc * taco::TableDesc::Create ( std::shared_ptr< const SysTable_Table >  table, const std::vector< const SysTable_Column * > &  columns  )

static

Creates a new table descriptor by building the schema object constructed from the columns (which performs lookups in the global catalog cache instance g_catcache).

Create() [2/2]

TableDesc * taco::TableDesc::Create ( std::shared_ptr< const SysTable_Table >  table, std::unique_ptr< Schema >  schema  )

static

This overload simply passes the arguments to the constructor.

GetSchema()

const Schema* taco::TableDesc::GetSchema ( ) const

inline

Returns the cached table schema, which we guanrantee ‘IsLayoutComputed() == true’.

GetTableEntry()

const SysTable_Table* taco::TableDesc::GetTableEntry ( ) const

inline

Returns the cached Table entry associated with this table descriptor.

Note that the table entry may be destructed as well if the table descriptor is destructed, so you must access the table entry while the table descriptor is still alive.
