@type:BULLET:@items[o:RDoc::Markup::ListItem:@label0;[o;	;[I"0store#[](key)         - Used to get a value;To;;0;[o;	;[I"0store#[]=(key, value) - Used to set a value;To;;0;[o;	;[I"1store#keys            - Used to get all keys;T@o;	;[I"GSince these stores only supports string, all values are converted ;TI"Fto JSON before being stored, allowing it to also store booleans, ;TI"Chashes and arrays. However, this store does not support Procs.;T@o;	;[I"JAs the ActiveRecord backend, Symbols are just supported when loading ;TI"Mtranslations from the filesystem or through explicit store translations.;T@o;	;[I"EAlso, avoid calling I18n.available_locales since it's a somehow ;TI"(expensive operation in most stores.;T@S:RDoc::Markup::Heading:

;T:@format0S;;i;I"Performance;T@o;	;[I"LYou may make this backend even faster by including the Memoize module. ;TI"LHowever, notice that you should properly clear the cache if you change ;TI"&values directly in the key-store.;T@S;;i;I"
Subtrees;T@o;	;[I"NIn most backends, you are allowed to retrieve part of a translation tree:;T@o;;[I"CI18n.backend.store_translations :en, :foo => { :bar => :baz }
;TI"'I18n.t "foo" #=> { :bar => :baz }
;T;0o;	;[I"RThis backend supports this feature by default, but it slows down the storage ;TI"Sof new data considerably and makes hard to delete entries. That said, you are ;TI"Ballowed to disable the storage of subtrees on initialization:;T@o;;[I"0I18n::Backend::KeyValue.new(@store, false)
;T;0o;	;[I"TThis is useful if you are using a KeyValue backend chained to a Simple backend.;T:
