如何使用golang遍历Aerospike中的列表？

Question

I am using the list data type (http://www.aerospike.com/docs/guide/cdt-list.html ) in aerospike using a golang client. I can use the ListInsertOp (https://godoc.org/github.com/aerospike/aerospike-client-go#ListInsertOp) to insert values in the list of a given entry.

However, I want to update/delete a given list value using the ListSetOp (https://godoc.org/github.com/aerospike/aerospike-client-go#ListSetOp) or the ListRemoveOp (https://godoc.org/github.com/aerospike/aerospike-client-go#ListRemoveOp)

In order to do this, I need an index. How can I get this index ? Is there a way I can iterate through all the list values and get the index and then perform the update or delete operation ?

Assuming that you have the list called List. Let us say you want to replace element called value with newItem You can do that like:

...

for index, item := range List {
     if item == value {
             List[index] = newItem
     }
}

...

In the above snippet, index is the index at which element item is present. By this way you can also replace element present on the particular index in the list with value.
