Detailed Description

template<typename Tp_, unsigned PgSz_ = 4, typename PgTp_ = lru_pager<8>, unsigned BlkSize_ = STXXL_DEFAULT_BLOCK_SIZE(Tp_), typename AllocStr_ = STXXL_DEFAULT_ALLOC_STRATEGY, typename SzTp_ = stxxl::uint64>
class vector< Tp_, PgSz_, PgTp_, BlkSize_, AllocStr_, SzTp_ >

External vector container.

For semantics of the methods see documentation of the STL std::vector Template parameters:

• Tp_ type of contained objects
• PgSz_ number of blocks in a page
• PgTp_ pager type, random_pager<x> or lru_pager<x>, where x is number of pages, default is lru_pager<8>
• BlkSize_ external block size in bytes, default is 2 Mbytes
• AllocStr_ one of allocation strategies: striping , RC , SR , or FR default is RC
  Memory consumption: BlkSize_*x*PgSz_ bytes

  Warning:

  Do not store references to the elements of an external vector. Such references might be invalidated during any following access to elements of the vector

vector< Tp_, PgSz_, PgTp_, BlkSize_, AllocStr_, SzTp_ >::vector

(

)

[inline]

Construct vector from a file.

Parameters:

from

file to be constructed from

Warning:

Only one vector can be assigned to a file (does not matter whether the files are different file objects). The block size of the vector must me a multiple of the element size sizeof(Tp_) and the page size (4096).

References file::get_disk_number(), config::get_instance(), block_manager::get_instance(), typed_block< RawSize_, T_, NRef_, InfoType_ >::raw_size, and file::set_size().
