Interface PasswordCallback

All Superinterfaces:

Supplier<String>

All Known Implementing Classes:

CryptCodecProvider

Functional Interface:

This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.

@FunctionalInterface
public interface PasswordCallback
extends Supplier<String>

Callback which can be used by CryptCodecProvider to retrieve a password on demand, at the time it is required. The callback will only be invoked if it is determined that a file actually requires a password to be opened. This could be used to implement a password user prompt utility. Note, CryptCodecProvider now accepts a Supplier as the password callback, so this interface is no longer necessary (kept for historical compatibility).
