Base class for random access stores

DEPRECATED

Use random-access-storage instead.

abstract-random-access

Base class for random access stores, such as

• random-access-file
• random-access-memory

Features

• ensures the store has been .open()ed
• verifies and defaults arguments
• provides stubs for unimplemented functions
• emits open and close events

Example

var Abstract = require('abstract-random-access')
var inherits = require('inherits')

var Store = function () {
  Abstract.call(this)  
}

inherits(Store, Abstract)

Store.prototype._read = function (offset, length, callback) {
  process.nextTick(function () {
    callback(null, Buffer('ohai'))  
  })  
}

abstract-random-access's Issues

Implement a stat interface

Random access classes lack a generalized stat interface to obtain basic information about the store such as its size. In both file and memory implementations, a length property is available to be used in such an implementation. That said, an optional stat property should exist in the abstract for implementors to establish methods that conform to this API, so consumers can examine stats for their stores.
