instance method Element#store

Element#store(key, value) → Element
Element#store(object) → Element

Stores a key/value pair of custom metadata on the element. If it is given one argument instead of two, it treats that argument as an object of key/value pairs, and stores each pair as element metadata.

The metadata can later be retrieved with Element.retrieve.

This method can be called either as an instance method or as a generic method. If calling as a generic, pass the instance in as the first argument.
