typedef vector< Tp_, PgSz_, PagerType, BlkSize_, AllocStr_ >	result

Detailed Description

template<typename Tp_, unsigned PgSz_ = 4, unsigned Pages_ = 8, unsigned BlkSize_ = STXXL_DEFAULT_BLOCK_SIZE(Tp_), typename AllocStr_ = STXXL_DEFAULT_ALLOC_STRATEGY, pager_type Pager_ = lru>
struct VECTOR_GENERATOR< Tp_, PgSz_, Pages_, BlkSize_, AllocStr_, Pager_ >

External vector type generator.

Template Parameters

Tp_	type of contained objects (POD with no references to internal memory)
PgSz_	number of blocks in a page
Pages_	number of pages
BlkSize_	external block size in bytes, default is 2 MiB
AllocStr_	one of allocation strategies: striping , RC , SR , or FR default is RC
Pager_	pager type: random , lru , is default

Memory consumption of constructed vector is BlkSize_*Pages_*PgSz_ bytes Configured vector type is available as STACK_GENERATOR<>::result.

Examples:

• VECTOR_GENERATOR<double>::result external vector of double's ,
• VECTOR_GENERATOR<double,8>::result external vector of double's , with 8 blocks per page,
• VECTOR_GENERATOR<double,8,2,512*1024,RC,lru>::result external vector of double's , with 8 blocks per page, 2 pages, 512 KiB blocks, Random Cyclic allocation and lru cache replacement strategy

  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
