Access memory using small fixed sized buffers
npm install memory-pagerAccess memory using small fixed sized buffers instead of allocating a huge buffer.
Useful if you are implementing sparse data structures (such as large bitfield).
``
npm install memory-pager
` js
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
`
#### 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
` js`
{
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
