Object-mapper is a project mainly written in Ruby, based on the MIT license.
Provides interface for operations above set of objects in single call. Binds method calls to all contained objects according to specified rules.
Object Mapper provides interface for operations above set of objects in single call. Binds method calls to all contained objects according to specified rules. So, for example, it's possible to work with many hashes by rather native way as with single one without necessity to merge them. For example:
require "mapper"
h1 = {:a => :b}
h2 = {:c => :d}
h3 = {:a => :e}
hashes = Mapper[h1, h2, h3]
hashes.some.has_key? :a # will return true
hashes.some[:c] # will return :d
Conditions according which some reductor will return value can be
changed. (It simply converts returned value of hash to boolean and
returns it if conversion is true
.) Let's change selector:
hashes.some{ |v| v == :e }[:a]
# will return :e, because :b conversion of first hash to boolean
# is false, so will continue to second and then to third hash where
# :a will return :e which is correct and therefore it will
# be returned
This example is slightly non-sense for practical use, of sure, but demonstrates how selector works well. Second available reductor is all which simply returns all results of method calls for each hash (in array):
hashes.all.has_key? :a # will return [true, false, true]
