| <P> |
| Abstract store manager implementation to ease development of custom |
| OpenJPA back-ends. A concrete subclass must define implementations for the |
| following methods: |
| <ul> |
| <li><A HREF="../../../../org/apache/openjpa/kernel/StoreManager.html#exists(org.apache.openjpa.kernel.OpenJPAStateManager, java.lang.Object)"><CODE>StoreManager.exists(org.apache.openjpa.kernel.OpenJPAStateManager, java.lang.Object)</CODE></A></li> |
| <li><A HREF="../../../../org/apache/openjpa/abstractstore/AbstractStoreManager.html#initialize(org.apache.openjpa.kernel.OpenJPAStateManager, org.apache.openjpa.kernel.PCState, org.apache.openjpa.kernel.FetchConfiguration, java.lang.Object)"><CODE>initialize(org.apache.openjpa.kernel.OpenJPAStateManager, org.apache.openjpa.kernel.PCState, org.apache.openjpa.kernel.FetchConfiguration, java.lang.Object)</CODE></A></li> |
| <li><A HREF="../../../../org/apache/openjpa/abstractstore/AbstractStoreManager.html#load(org.apache.openjpa.kernel.OpenJPAStateManager, java.util.BitSet, org.apache.openjpa.kernel.FetchConfiguration, int, java.lang.Object)"><CODE>load(org.apache.openjpa.kernel.OpenJPAStateManager, java.util.BitSet, org.apache.openjpa.kernel.FetchConfiguration, int, java.lang.Object)</CODE></A></li> |
| <li><A HREF="../../../../org/apache/openjpa/abstractstore/AbstractStoreManager.html#flush(java.util.Collection, java.util.Collection, java.util.Collection, java.util.Collection, java.util.Collection)"><CODE>flush(Collection,Collection,Collection,Collection,Collection)</CODE></A></li> |
| <li><A HREF="../../../../org/apache/openjpa/abstractstore/AbstractStoreManager.html#executeExtent(org.apache.openjpa.meta.ClassMetaData, boolean, org.apache.openjpa.kernel.FetchConfiguration)"><CODE>executeExtent(org.apache.openjpa.meta.ClassMetaData, boolean, org.apache.openjpa.kernel.FetchConfiguration)</CODE></A></li> |
| </ul> Additionally, subclasses should not attempt to acquire resources |
| until <A HREF="../../../../org/apache/openjpa/abstractstore/AbstractStoreManager.html#open()"><CODE>open()</CODE></A> has been called. Store manager instances might be |
| created to call metadata methods such as <A HREF="../../../../org/apache/openjpa/abstractstore/AbstractStoreManager.html#newConfiguration()"><CODE>newConfiguration()</CODE></A> or |
| <A HREF="../../../../org/apache/openjpa/abstractstore/AbstractStoreManager.html#getUnsupportedOptions()"><CODE>getUnsupportedOptions()</CODE></A> and never opened. These instances should |
| not consume any data store resources. |
| Notes: |
| <ul> |
| <li>The <A HREF="../../../../org/apache/openjpa/kernel/StoreManager.html#initialize(org.apache.openjpa.kernel.OpenJPAStateManager, org.apache.openjpa.kernel.PCState, org.apache.openjpa.kernel.FetchConfiguration, java.lang.Object)"><CODE>StoreManager.initialize(org.apache.openjpa.kernel.OpenJPAStateManager, org.apache.openjpa.kernel.PCState, org.apache.openjpa.kernel.FetchConfiguration, java.lang.Object)</CODE></A> method is responsible |
| for creating new instances of objects freshly loaded from the |
| database. The method will be invoked with a <A HREF="../../../../org/apache/openjpa/kernel/OpenJPAStateManager.html" title="interface in org.apache.openjpa.kernel"><CODE>OpenJPAStateManager</CODE></A> |
| that the newly-loaded object should be associated with. To create the |
| new object and set up this association correctly, the implementation |
| should use the <A HREF="../../../../org/apache/openjpa/kernel/OpenJPAStateManager.html#initialize(java.lang.Class, org.apache.openjpa.kernel.PCState)"><CODE>OpenJPAStateManager.initialize(java.lang.Class, org.apache.openjpa.kernel.PCState)</CODE></A> method.</li> |
| <li>If your data store supports some sort of transaction or |
| unit of work, you should override the <A HREF="../../../../org/apache/openjpa/abstractstore/AbstractStoreManager.html#begin()"><CODE>begin()</CODE></A>, <A HREF="../../../../org/apache/openjpa/abstractstore/AbstractStoreManager.html#commit()"><CODE>commit()</CODE></A>, |
| and <A HREF="../../../../org/apache/openjpa/abstractstore/AbstractStoreManager.html#rollback()"><CODE>rollback()</CODE></A> methods.</li> |
| <li>This class provides no infrastructure support for optimistic |
| transactions. To provide optimistic transaction support: |
| <ul> |
| <li>Override <A HREF="../../../../org/apache/openjpa/abstractstore/AbstractStoreManager.html#beginOptimistic()"><CODE>beginOptimistic()</CODE></A>, <A HREF="../../../../org/apache/openjpa/abstractstore/AbstractStoreManager.html#rollbackOptimistic()"><CODE>rollbackOptimistic()</CODE></A>, |
| and <A HREF="../../../../org/apache/openjpa/abstractstore/AbstractStoreManager.html#syncVersion(org.apache.openjpa.kernel.OpenJPAStateManager, java.lang.Object)"><CODE>syncVersion(org.apache.openjpa.kernel.OpenJPAStateManager, java.lang.Object)</CODE></A>.</li> |
| <li>Override <A HREF="../../../../org/apache/openjpa/abstractstore/AbstractStoreManager.html#getUnsupportedOptions()"><CODE>getUnsupportedOptions()</CODE></A> to not include <A HREF="../../../../org/apache/openjpa/conf/OpenJPAConfiguration.html#OPTION_OPTIMISTIC"><CODE>OpenJPAConfiguration.OPTION_OPTIMISTIC</CODE></A> in the list of unsupported |
| options.</li> |
| <li>Ensure that your flush implementation sets the next |
| version for each modified object via the <A HREF="../../../../org/apache/openjpa/kernel/OpenJPAStateManager.html#setNextVersion(java.lang.Object)"><CODE>OpenJPAStateManager.setNextVersion(java.lang.Object)</CODE></A> method.</li> |
| <li>If your version object does not implement <A HREF="http://download.oracle.com/javase/6/docs/api/java/lang/Comparable.html?is-external=true" title="class or interface in java.lang"><CODE>Comparable</CODE></A>, |
| override <A HREF="../../../../org/apache/openjpa/abstractstore/AbstractStoreManager.html#compareVersion(org.apache.openjpa.kernel.OpenJPAStateManager, java.lang.Object, java.lang.Object)"><CODE>compareVersion(org.apache.openjpa.kernel.OpenJPAStateManager, java.lang.Object, java.lang.Object)</CODE></A>, which relies on the |
| <A HREF="http://download.oracle.com/javase/6/docs/api/java/lang/Comparable.html?is-external=true#compareTo(T)" title="class or interface in java.lang"><CODE>Comparable.compareTo(T)</CODE></A> method.</li> |
| </ul></li> |
| <li>If your data store supports a mechanism for automatically |
| generating and managing identity values (or if you want to |
| provide that facility on top of your data store), implement |
| the <A HREF="../../../../org/apache/openjpa/abstractstore/AbstractStoreManager.html#getDataStoreIdSequence(org.apache.openjpa.meta.ClassMetaData)"><CODE>getDataStoreIdSequence(org.apache.openjpa.meta.ClassMetaData)</CODE></A> method if you want to use a |
| <code>long</code> as your datastore identity type and are |
| happy with OpenJPA's <A HREF="../../../../org/apache/openjpa/util/Id.html" title="class in org.apache.openjpa.util"><CODE>Id</CODE></A> class. To use another datastore identity |
| type, override <A HREF="../../../../org/apache/openjpa/abstractstore/AbstractStoreManager.html#getManagedType(java.lang.Object)"><CODE>getManagedType(java.lang.Object)</CODE></A>, |
| <A HREF="../../../../org/apache/openjpa/abstractstore/AbstractStoreManager.html#getDataStoreIdType(org.apache.openjpa.meta.ClassMetaData)"><CODE>getDataStoreIdType(org.apache.openjpa.meta.ClassMetaData)</CODE></A>, <A HREF="../../../../org/apache/openjpa/abstractstore/AbstractStoreManager.html#copyDataStoreId(java.lang.Object, org.apache.openjpa.meta.ClassMetaData)"><CODE>copyDataStoreId(java.lang.Object, org.apache.openjpa.meta.ClassMetaData)</CODE></A>, and |
| <A HREF="../../../../org/apache/openjpa/abstractstore/AbstractStoreManager.html#newDataStoreId(java.lang.Object, org.apache.openjpa.meta.ClassMetaData)"><CODE>newDataStoreId(java.lang.Object, org.apache.openjpa.meta.ClassMetaData)</CODE></A> instead. In either case, override |
| <A HREF="../../../../org/apache/openjpa/abstractstore/AbstractStoreManager.html#getUnsupportedOptions()"><CODE>getUnsupportedOptions()</CODE></A> to not include |
| <A HREF="../../../../org/apache/openjpa/conf/OpenJPAConfiguration.html#OPTION_ID_DATASTORE"><CODE>OpenJPAConfiguration.OPTION_ID_DATASTORE</CODE></A> in the list of |
| unsupported options.</li> |
| <li>If your data store does not support queries (or if you do |
| not want to convert OpenJPA's query parse tree into a |
| datastore-specific query), you still have two options in terms |
| of query execution: |
| <ul> |
| <li><em>In-memory execution</em>: If you |
| execute a query against an extent or a class, OpenJPA will |
| automatically load the full extent of objects into memory and |
| execute the query in memory.</li> |
| <li><em>openjpa.MethodQL</em>: MethodQL allows |
| you to use the query APIs to execute a method that finds |
| data in your back-end and returns that data as a |
| <A HREF="../../../../org/apache/openjpa/lib/rop/ResultList.html" title="interface in org.apache.openjpa.lib.rop"><CODE>ResultList</CODE></A>. For more details on |
| MethodQL, see the OpenJPA Reference Guide.</li> |
| </ul></li> |
