When do we use an indexer?
Indexers have a variety of uses in (natural) language processing, etc, that's my limited understanding of the matter... Read on...
indexer we use it when we need to get something that is in an array or in a list. don't be frustrated by the term "indexer" it only mean that you tell the compiler to get this ( indexer ) from the list or array or a group of types. indexer is every type you use. for example from the array you want to get the fifth one so you say array the number 4 is the indexer of type int.
Thanks for the answers!
The table indexers, under DB, are used to speed up the data access read. Use whit thrift! Or the servers performance go down!
Commonly in arrays/collections, if I am not misstaken. Most often like this: array[index]
