|
|
* Document-class: SDBM
|
|
|
|
*
|
|
|
|
* SDBM provides a simple file-based key-value store, which can only store
|
|
|
|
* String keys and values.
|
|
|
|
*
|
|
|
|
* Note that Ruby comes with the source code for SDBM, while the DBM and GDBM
|
|
|
|
* standard libraries rely on external libraries and headers.
|
|
|
|
*
|
|
|
|
* === Examples
|
|
|
|
*
|
|
|
|
* Insert values:
|
|
|
|
*
|
|
|
|
* require 'sdbm'
|
|
|
|
*
|
|
|
|
* SDBM.open 'my_database' do |db|
|
|
|
|
* db['apple'] = 'fruit'
|
|
|
|
* db['pear'] = 'fruit'
|
|
|
|
* db['carrot'] = 'vegetable'
|
|
|
|
* db['tomato'] = 'vegetable'
|
|
|
|
* end
|
|
|
|
*
|
|
|
|
* Bulk update:
|
|
|
|
*
|
|
|
|
* require 'sdbm'
|
|
|
|
*
|
|
|
|
* SDBM.open 'my_database' do |db|
|
|
|
|
* db.update('peach' => 'fruit', 'tomato' => 'fruit')
|
|
|
|
* end
|
|
|
|
*
|
|
|
|
* Retrieve values:
|
|
|
|
*
|
|
|
|
* require 'sdbm'
|
|
|
|
*
|
|
|
|
* SDBM.open 'my_database' do |db|
|
|
|
|
* db.each do |key, value|
|
|
|
|
* puts "Key: #{key}, Value: #{value}"
|
|
|
|
* end
|
|
|
|
* end
|
|
|
|
*
|
|
|
|
* Outputs:
|
|
|
|
*
|
|
|
|
* Key: apple, Value: fruit
|
|
|
|
* Key: pear, Value: fruit
|
|
|
|
* Key: carrot, Value: vegetable
|
|
|
|
* Key: peach, Value: fruit
|
|
|
|
* Key: tomato, Value: fruit
