Interface JndiCallback<T>

Type Parameters:

T - the resulting object type

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 JndiCallback<T>

Callback interface to be implemented by classes that need to perform an operation (such as a lookup) in a JNDI context. This callback approach is valuable in simplifying error handling, which is performed by the JndiTemplate class. This is a similar to JdbcTemplate's approach.

Note that there is hardly any need to implement this callback interface, as JndiTemplate provides all usual JNDI operations via convenience methods.
