Iterator for badgerDB
// Iterator adds an implementable target for variations of different Iterator's
// for simplification of functional code, that you can then implement this reduced
// interface such that primarily methods Rewind and Valid and Next are overloaded.
// usage:
// for iterator.Rewind(); iterator.Valid(); iterator.Next() {
// iterator.Item()
// ...
// }
// this is a general snippet of code that using this interface may have overloaded
// only Rewind and Valid are changes
type Iterator interface {
Rewind()
Valid() bool
Next()
Item() *badger.Item
}
This library also add 5 concrete iterators: prefix, from-to, from, to, prefix-from.
The library does not support backward key-scan (whence only a prefix-from)
Use the method biter.KeyRangeIterator and throw any combination of prefix, from and to at it to get the corresponding Iterator.
for some examples of functionality refer to queries_test.go

type Iterator ¶
Iterator adds an implementable target for variations of different Iterator(s) for simplification of functional code, that you can then implement this reduced interface such that primarily methods Rewind and Valid and Next are overloaded. usage:
for iterator.Rewind(); iterator.Valid(); iterator.Next() {
iterator.Item()
...
}
this is a general snippet of code that using this interface may have changed implementation only Rewind and Valid are changes
