Examples of krati.core.array.SimpleDataArray

krati.core.array.SimpleDataArray
SimpleDataArray provides an array like interface to get and set raw bytes at a specified array index. This class provides the core code for implementing different sub-classes of {@link krati.store.DataStore DataStore} and {@link krati.store.DataSet DataSet}.
This class is not thread-safe by design. It is expected that the conditions below hold within one JVM.
```
 1. There is one and only one instance of SimpleDataArray for a given home directory. 2. There is one and only one thread calling setData and transferTo methods at any given time.  
```
It is expected that this class is used in the case of multiple readers and single writer.

05/09, 2011 - added support for Closeable
05/22, 2011 - fixed method close()
05/23, 2011 - sync compaction batches in method close()
05/26, 2011 - added methods for partially reading data bytes
06/22, 2011 - catch SegmentException in method set() for safety
06/03, 2012 - fixed problematic sync upon calling method close()
06/11, 2012 - Simplified compaction update
08/31, 2012 - Enabled segment index buffer
09/09, 2012 - Removed throttling as compaction is efficient with SIB
