public Interface JndiCallback<T>

Annotations

@FunctionalInterface

Type Parameters

<T>: the resulting object type

Imports

javax.naming.Context, .NamingException, org.springframework.lang.Nullable

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.
