Interface SnmpAsyncWalker<V>

All Superinterfaces:

SnmpOperation<SnmpAsyncWalker<V>>, SnmpWalker<V>

public interface SnmpAsyncWalker<V>
extends SnmpWalker<V>, SnmpOperation<SnmpAsyncWalker<V>>

An object that walks a conceptual table asynchronously.

An asynchronous walker is an operation that when invoked, provides a reference to a walker that can be used to retrieve rows from the table. It's next() method will throw a WouldBlockException if an additional operation is required to get the next row (or to determine that the end of table has been reached). On receipt of this exception, the caller should then invoke the walker (as an operation) to continue.
