<div class="block">A store for managing persistent entity objects.
<p><code>EntityStore</code> objects are thread-safe. Multiple threads may safely
call the methods of a shared <code>EntityStore</code> object.</p>
<p>See the <a href="package-summary.html#example">package
summary example</a> for an example of using an <code>EntityStore</code>.</p>
<p>Before creating an <code>EntityStore</code> you must create an <a href="../../../com/sleepycat/db/Environment.html" title="class in com.sleepycat.db"><code>Environment</code></a> object using the Berkeley DB engine API. The environment may
contain any number of entity stores and their associated databases, as well
as other databases not associated with an entity store.</p>
<p>An entity store is based on an <a href="../../../com/sleepycat/persist/model/EntityModel.html" title="class in com.sleepycat.persist.model"><code>EntityModel</code></a>: a data model which
defines persistent classes (<em>entity classes</em>), primary keys,
secondary keys, and relationships between entities. A primary index is
created for each entity class. An associated secondary index is created for
each secondary key. The <a href="../../../com/sleepycat/persist/model/Entity.html" title="annotation in com.sleepycat.persist.model"><code>Entity</code></a>, <a href="../../../com/sleepycat/persist/model/PrimaryKey.html" title="annotation in com.sleepycat.persist.model"><code>PrimaryKey</code></a> and <a href="../../../com/sleepycat/persist/model/SecondaryKey.html" title="annotation in com.sleepycat.persist.model"><code>SecondaryKey</code></a> annotations may be used to define entities and keys.</p>
<p>To use an <code>EntityStore</code>, first obtain <a href="../../../com/sleepycat/persist/PrimaryIndex.html" title="class in com.sleepycat.persist"><code>PrimaryIndex</code></a> and
<a href="../../../com/sleepycat/persist/SecondaryIndex.html" title="class in com.sleepycat.persist"><code>SecondaryIndex</code></a> objects by calling <a href="../../../com/sleepycat/persist/EntityStore.html#getPrimaryIndex(java.lang.Class,%20java.lang.Class)"><code>getPrimaryIndex</code></a> and <a href="../../../com/sleepycat/persist/EntityStore.html#getSecondaryIndex(com.sleepycat.persist.PrimaryIndex,%20java.lang.Class,%20java.lang.String)"><code>getSecondaryIndex</code></a>. Then use
these indices to store and access entity records by key.</p>
<p>Although not normally needed, you can also use the entity store along
with the <a href="../../../com/sleepycat/db/package-summary.html"><code>Base API</code></a>. Methods in the <a href="../../../com/sleepycat/persist/PrimaryIndex.html" title="class in com.sleepycat.persist"><code>PrimaryIndex</code></a> and <a href="../../../com/sleepycat/persist/SecondaryIndex.html" title="class in com.sleepycat.persist"><code>SecondaryIndex</code></a> classes may be used to obtain
databases and bindings. The databases may be used directly for accessing
entity records. The bindings should be called explicitly to translate
between <a href="../../../com/sleepycat/db/DatabaseEntry.html" title="class in com.sleepycat.db"><code>DatabaseEntry</code></a> objects and entity model
objects.</p>
<p>Each primary and secondary index is associated internally with a <a href="../../../com/sleepycat/db/Database.html" title="class in com.sleepycat.db"><code>Database</code></a>. With any of the above mentioned use cases, methods are provided
that may be used for database performance tuning. The <a href="../../../com/sleepycat/persist/EntityStore.html#setPrimaryConfig(java.lang.Class,%20com.sleepycat.db.DatabaseConfig)"><code>setPrimaryConfig</code></a> and <a href="../../../com/sleepycat/persist/EntityStore.html#setSecondaryConfig(java.lang.Class,%20java.lang.String,%20com.sleepycat.db.SecondaryConfig)"><code>setSecondaryConfig</code></a> methods may be called anytime before a database is
opened via <a href="../../../com/sleepycat/persist/EntityStore.html#getPrimaryIndex(java.lang.Class,%20java.lang.Class)"><code>getPrimaryIndex</code></a> or <a href="../../../com/sleepycat/persist/EntityStore.html#getSecondaryIndex(com.sleepycat.persist.PrimaryIndex,%20java.lang.Class,%20java.lang.String)"><code>getSecondaryIndex</code></a>. The <a href="../../../com/sleepycat/persist/EntityStore.html#setSequenceConfig(java.lang.String,%20com.sleepycat.db.SequenceConfig)"><code>setSequenceConfig</code></a> method may be called anytime before <a href="../../../com/sleepycat/persist/EntityStore.html#getSequence(java.lang.String)"><code>getSequence</code></a> is called or <a href="../../../com/sleepycat/persist/EntityStore.html#getPrimaryIndex(java.lang.Class,%20java.lang.Class)"><code>getPrimaryIndex</code></a> is called
for a primary index associated with that sequence.</p></div>
