BDB::Recnum

Don't mix these methods with methods of <em>BDB::Cursor</em>

All instance methods has the same syntax than the methods of Array

BDB::Recnum.open(name, subname, flags, mode)

is equivalent to

BDB::Recno.open(name, subname, flags, mode, "set_flags" => BDB::RENUMBER, "set_array_base" => 0)

Inherit from BDB::Common

end
[](args) click to toggle source

Element reference - with the following syntax

self

retrieves the nth item from an array. Index starts from zero. If index is the negative, counts backward from the end of the array. The index of the last element is -1. Returns nil, if the nth element is not exist in the array.

self

returns an array containing the objects from start to end, including both ends. if end is larger than the length of the array, it will be rounded to the length. If start is out of an array range , returns nil. And if start is larger than end with in array range, returns empty array ([]).

self[start, length]

returns an array containing length items from start. Returns nil if length is negative.

# File comxxx.rb, line 160
def  [](args) 
end
[]=(args, val) click to toggle source

Element assignement -- with the following syntax

self = val

changes the nth element of the array into val. If nth is larger than array length, the array shall be extended automatically. Extended region shall be initialized by nil.

self = val

replace the items from start to end with val. If val is not an array, the type of val will be converted into the Array using to_a method.

self[start, length] = val

replace the length items from start with val. If val is not an array, the type of val will be converted into the Array using to_a.
