The Grails Framework 3.3.3

(Quick Reference) ## load ### Purpose Returns a proxy instance of the domain class for the given identifier. ### Examples
    // load a single instance
    def b = Book.load(1)
    String title = b.title
    ...

    // delete an instance without retrieving it
    Book.load(1).delete()
### Description `load` usually returns a proxy for the instance which is initialized on-demand, when a method other than `getId()` is invoked. `load()` only returns `null` if the provided id is `null`, so you cannot use it to test for existence. If you provide an id for an instance that doesn’t exist, a proxy will be returned and an exception will be thrown only when you call any instance method other than `getId()`. If there is an existing instance with the same id in the Hibernate session or 2nd-level cache, load() will return that non-proxy instance instead of a proxy. Parameters: `id` - The id of the object to retrieve | Quick Reference (hide)
