Interface ProxyStore

All Known Implementing Classes:
  DefaultProxyStore

    public interface ProxyStore

A ProxyStore provides a `ProxySerializer` with access to a low-level persistence mechanism. The ProxyStore does not need to be able to interpret the data sent to it by the ProxySerializer; it is merely a wrapper around a persistence mechanism.

  `DefaultProxyStore`

Method Summary
`Splittable` | `get(java.lang.String key)` Called by `ProxySerializer` to retrieve a value previously provided to `put(String, Splittable)`.
`int` | `nextId()` Returns a non-negative sequence number.
`void` | `put(java.lang.String key, Splittable value)` Called by `ProxySerializer` to store a value.

### nextId

    int nextId()
