Method: Moneta::Defaults#fetch_values

Defined in:

lib/moneta/mixins.rb

#fetch_values(*keys, **options) ⇒ Object #fetch_values(*keys, **options) {|key| ... } ⇒ Array<Object, nil>

Note:

Some adapters may implement this method atomically. The default implmentation uses #values_at.

Behaves identically to #values_at except that it accepts an optional block. When supplied, the block will be called successively with each supplied key that is not present in the store. The return value of the block call will be used in place of nil in returned the array of values.

Overloads:

• #fetch_values(*keys, **options) {|key| ... } ⇒ Array<Object, nil>

  Returns Array containing the values requested, or where keys are missing, the return values from the corresponding block calls.

  Yield Parameters:

  • key (Object) —

    Each key that is not found in the store

  Yield Returns:

  • (Object, nil) —

    The value to substitute for the missing one

  Returns:

  • Array containing the values requested, or where keys are missing, the return values from the corresponding block calls
