类名称：Element
方法名：prepareMutation

Element.prepareMutation介绍

[英]Prepares a mutation to allow changing multiple property values at the same time. This method is similar to Graph#prepareVertex(Visibility, Authorizations) in that it allows multiple properties to be changed and saved in a single mutation.
