Functions ¶
func Next ¶
Next advances the iterator returning true if it was successful (and you can use Value to get value for slices or key-value pair for maps) and false otherwise (and there are no more elements in this Iterator). This function uses `System.Iterator.Next` syscall.
func Value ¶
Value returns iterator's current value. It's only valid to call after a successful Next call. This function uses `System.Iterator.Value` syscall. For slices, the result is just value. For maps, the result can be cast to a slice of 2 elements: a key and a value. For storage iterators, refer to `storage.FindFlags` documentation.
Types ¶
type Iterator ¶
type Iterator struct{}
Iterator represents a Neo iterator, it's an opaque data structure that can be properly created by storage.Find. Iterators range over key-value pairs, so it's convenient to use them for maps. This structure is similar in function to Neo .net framework's Iterator.
