Implementation of a cached block/stream data store with write-ahead
logging. Individual pages
are accessed through an LRU cache. Subpage allocators implement smaller
granularity allocations. Arbitrary size objects can accessesd as streams.

| Block.java | Class | This class represents a block/page of data in a random access file,
which may be cached. |
| BlockAccess.java | Class | This class implements a randomly accessible, growable region within
a BlockFile object. |
| BlockCache.java | Class | This class manages a number of buffers on an underlying store. |
| BlockFile.java | Class | This class is used to create, modify, or read a blocked file. |
| BlockPath.java | Class | This class is used to locate a specified offset within a randomly
accessible BlockAccess object. |
| BlockStore.java | Class | Below the cache, this class handles the actual I/O to the underlying file. |
| BufferedRandomAccess.java | Class | A RandomAccess implementation using a byte array. |
| ByteArrayRandomAccess.java | Class | A RandomAccess implementation using a byte array. |
| ByteUtil.java | Class | This class encapsulates various utilities for manipulating byte arrays
which contain primitive values, such as integers, strings, etc. |
| Cache.java | Class | This class manages a number of buffers on an underlying store. |
| Cacheable.java | Class | The construction of these objects needs to be managed by the
cache object. |
| Datafile.java | Class | This class brings together the various file-level components of the
structured (SQL) database. |

| Logger.java | Interface | |
| Logger1.java | Class | A Logger implmeentation using a fixed size circular buffer. |
| LogOp.java | Interface | |
| MemoryBlockStore.java | Class | Below the cache, this class handles the actual I/O to the underlying file. |
| NullStore.java | Class | The null store, which is part of the memory-only implementation. |
| Page.java | Interface | This interface models a page of data in a block file, either a main page
(aka a Block) or a sub-page. |
| PageManager.java | Interface | Interface to be implemented by page (and sub-page) allocators. |
| RandomAccess.java | Class | |
| RandomAccessInputStream.java | Class | An input stream attached to a RandomAccess object. |
| RandomAccessOutputStream.java | Class | An output stream attached to a RandomAccess object. |
| SegmentManager.java | Interface | |
| SubPage.java | Class | This class implements a page allocated by a sub-page allocator. |
| SubPageManager.java | Class | This class implements a sub-page manager which operates by allocating
pages as needed from the main file and chopping them up into smaller
pages of the appropriate size. |
