Efficiently retrieve multiple properties from an object. @param pathSet (see collect!) @yield [*values] Property values in same order as pathSet. @return [Array] Property values in same order as pathSet, or the return

value from the block if it is given.

Efficiently retrieve multiple properties from an object. @param pathSet [Array] Properties to return. @return [Hash] Hash from property paths to values.

wait_until(*pathSet, &b) click to toggle source

Wait for updates on an object until a condition becomes true.

@param pathSet [Array] Property paths to wait for updates to. @yield Called when an update to a subscribed property occurs. @yieldreturn [Boolean] Whether to stop waiting.

@todo Pass the current property values to the block.
