Overview

initialize( path_to_filename )
self.create_table( path_to_basename ) --- method to create new table --- ex. NERA::Database.create_table( "./db")
add( new_rec ) --- add a new record to the table. --- new_rec must be specified by a Hash. --- ex. db.add( { :key1 => 'test', :key2 => DateTime.now, ... } ) --- You don't need to specify the ':id' key. If it is specified, it is omitted. --- During the transaction, files are locked with exclusive locks. --- return true if the addition succeeded. --- raise RuntimeError if the specified hash is not valid.
find_by_id( id ) --- returns records in Hash. --- id can be Integer, Array of Integers, or Range of Integers. --- During reading file, the files are locked with shared locks. --- If there are several records, it returns Array of Hash.
find_all { |rec| (condition) } --- returns the array of the matched records. --- return nil if no record matched.
update( rec ) --- update a record --- ex. db.update( :key1=>'updated', :key2=>DateTime.now ) --- returns nil if the record of the specified 'id' does not exist.
destroy( id ) --- destroy records --- id may be an Integer, Array of Integers, Range --- if the specified record is not found in the table, return nil.
transaction { ..(transaction).. } --- all the database files are exclusively locked during block is processed. --- database files are unlocked at the end of the block. terminates. --- sample -----------

db.transaction do arr = db.find_all do |record| record > 5 end

arr.each do |rec| rec[:state] = finished end
db.update( arr)

end

--- end of sample ---
