Puts the given value under the given key into this index engine. Validates the operation using the provided validator.

Parameters:

atomicOperation -

key - the key to put the value under.

value - the value to put.

validator - the operation validator.

Returns:

true if the validator allowed the put, false otherwise.

Throws:

IOException
