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 stxxl::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
