    memory-pager

    Access memory using small fixed sized buffers instead of allocating a huge buffer. Useful if you are implementing sparse data structures (such as large bitfield).

    travis

    npm install memory-pager
    

    Usage

    var pager = require('paged-memory')
     
    var pages = pager(1024) // use 1kb per page
     
    var page = pages.get(10) // get page #10
     
    console.log(page.offset) // 10240
    console.log(page.buffer) // a blank 1kb buffer

    API

    var pages = pager(pageSize)

    Create a new pager. pageSize defaults to 1024.

    var page = pages.get(pageNumber, [noAllocate])

    Get a page. The page will be allocated at first access.

    Optionally you can set the noAllocate flag which will make the method return undefined if no page has been allocated already

    A page looks like this

    {
      offset: byteOffset,
      buffer: bufferWithPageSize
    }

    pages.set(pageNumber, buffer)

    Explicitly set the buffer for a page.

    pages.updated(page)

    Mark a page as updated.

    pages.lastUpdate()

    Get the last page that was updated.

    var buf = pages.toBuffer()

    Concat all pages allocated pages into a single buffer
