Java Source Code / Java Documentation » Database ORM » XORM » org.xorm   Source Cross Reference   Class Diagram   Java Document (Java Doc)   java.lang.Object    org.xorm.InterfaceManager InterfaceManager class InterfaceManager implements PersistenceManager,I15d(Code) Roughly equivalent to JDO PersistenceManager. Developers should always acquire an InterfaceManager as a javax.jdo.PersistenceManager. The implementation details are transparent to the use of the API. To use additional XORM features, the org.xorm.XORM static methods are provided.

Constructor Detail InterfaceManager InterfaceManager(InterfaceManagerFactory factory, Options jdoOptions)(Code) Creates a new InterfaceManager. This method is called from the InterfaceManagerFactory. Method Detail addToCache void addToCache(Row row)(Code) addToCache void addToCache(Collection rows)(Code) close public synchronized void close()(Code) Marks this InterfaceManager as closed. Closing an InterfaceManager ensures that any datastore resources being used will be disconnected. After a call to close(), all methods of the PersistenceManager interface (with the exception of isClosed()) will throw JDOFatalUserException. Calling close() while a Transaction is active will throw a JDOUserException. currentTransaction public Transaction currentTransaction()(Code) Returns the transaction associated with this InterfaceManager. Merely retrieving the transaction does not change its state; you must call begin(), commit(), etc. deletePersistent public void deletePersistent(Object object)(Code) deletePersistentAll public void deletePersistentAll(Collection collection)(Code) deletePersistentAll public void deletePersistentAll(Object[] array)(Code) evict public void evict(Object object)(Code) This operation is not currently supported. evictAll public void evictAll(Object[] array)(Code) This operation is not currently supported. evictAll public void evictAll(Collection collection)(Code) This operation is not currently supported. evictAll public void evictAll()(Code) This operation is not currently supported. executeSizeQuery int executeSizeQuery(Selector selector)(Code) finalize public void finalize()(Code) When an InterfaceManager is garbage collected, ensure that any active transactions are closed. getExtent public Extent getExtent(Class clazz, boolean subclasses)(Code) Returns the Extent of the given class. Subclasses are not supported yet. getFromCache Row getFromCache(Table table, Object primaryKey)(Code) getIgnoreCache public boolean getIgnoreCache()(Code) Returns the value of the ignoreCache flag. Not that it will do you much good. getInterfaceManagerFactory InterfaceManagerFactory getInterfaceManagerFactory()(Code) getMultithreaded public boolean getMultithreaded()(Code) Returns the value of the multithreaded flag, which XORM blithely ignores. getObjectById public Object getObjectById(Object object, boolean validate)(Code) getObjectId public Object getObjectId(Object object)(Code) Attempts to identify the primaryKey for the object. Returns null if the object is not PersistenceCapable. getObjectIdClass public Class getObjectIdClass(Class clazz)(Code) If the class parameter is not mapped in a *.jdo file, returns null. Otherwise returns org.xorm.ObjectId.class. getObjectState ObjectState getObjectState(Object object)(Code) The incoming object may be an instance of either a reference-enhanced JDO class or a dynamically enhanced cglib-generated class. getPersistenceManagerFactory public PersistenceManagerFactory getPersistenceManagerFactory()(Code) getTransactionalObjectId public Object getTransactionalObjectId(Object object)(Code) At present, this is the same as getObjectId(). Changing an ObjectId is not supported. getUserObject public Object getUserObject()(Code) Retrieves the user-associated object. isClosed public boolean isClosed()(Code) Returns true if this manager object has been closed. lookup Object lookup(Class clazz, Object primaryKey)(Code) Retrieves an object from the cache or from persistent storage that is of the given type and has the matching object ID. Called from getObjectById and from RelationshipProxy.iterator() lookup Object lookup(ClassMapping classMapping, Object primaryKey)(Code) This is the primary method by which an object is acquired. This method may return a hollow object that has not been validated. Called from lookup(Class, Object) and from InterfaceInvocationHandler .invokeGet(). lookupRow Row lookupRow(ClassMapping classMapping, Object primaryKey)(Code) Retrieve a datastore row given its primary key. This method first checks the local cache, then calls DatastoreDriver.read(). If no matching row is found, JDOObjectNotFoundException is thrown. Called from lookup() and from InterfaceInvocationHandler.refresh(). makeNontransactional public void makeNontransactional(Object object)(Code) makeNontransactionalAll public void makeNontransactionalAll(Collection collection)(Code) makeNontransactionalAll public void makeNontransactionalAll(Object[] array)(Code) makePersistent public void makePersistent(Object object)(Code) Marks an object as persistent so it may be saved to the datastore. makePersistentAll public void makePersistentAll(Collection collection)(Code) Marks all items within a collection of objects as persistent. makePersistentAll public void makePersistentAll(Object[] array)(Code) Marks all items within an array of objects as persistent. makeTransactional public void makeTransactional(Object object)(Code) makeTransactionalAll public void makeTransactionalAll(Collection collection)(Code) makeTransactionalAll public void makeTransactionalAll(Object[] array)(Code) makeTransient public void makeTransient(Object object)(Code) makeTransientAll public void makeTransientAll(Collection collection)(Code) makeTransientAll public void makeTransientAll(Object[] array)(Code) newObjectIdInstance public Object newObjectIdInstance(Class clazz, String arg)(Code) Returns a new objectId corresponding to the given class and String parameter. newQuery public Query newQuery(Class clazz, String filter)(Code) Returns a query built using JDOQL. newQuery public Query newQuery(Class clazz)(Code) Returns a query for the specified class. Without user modification, when executed, returns all instances of the class. newQuery public Query newQuery(Extent extent)(Code) Returns a query for the specified extent. Without user modification, when executed, returns all instances of the class. Note that XORM does not support subclasses at this time. newQuery public Query newQuery(Extent extent, String filter)(Code) Returns a query for the specified extent. Without user modification, when executed, returns all instances of the class that match the query filter (JDOQL expression). Note that XORM does not support subclasses at this time. newQuery public Query newQuery()(Code) Creates a new query that the user must set values on using the Query interface. newQuery public Query newQuery(Object compiled)(Code) Constructs a query by copying data from a previous query. newQuery public Query newQuery(String language, Object query)(Code) Known languages are "javax.jdo.query.JDOQL" (which takes a String), "org.xorm.query.CodeQuery" (use CodeQuery.LANGUAGE), and QueryLanguage.LANGUAGE. newQuery public Query newQuery(Class clazz, Collection extent)(Code) This operation is not currently supported. newQuery public Query newQuery(Class clazz, Collection extent, String filter)(Code) This operation is not currently supported. refresh public void refresh(Object object)(Code) Reloads the fields of the object from the datastore. refreshAll public void refreshAll(Object[] array)(Code) Calls refresh() on all objects in the array. refreshAll public void refreshAll(Collection collection)(Code) Calls refresh() on all objects in the collection. refreshAll public void refreshAll()(Code) Refreshes all objects in the transaction. refreshColumns void refreshColumns(Row row, DataFetchGroup dfg)(Code) Refreshes particular fields of a Row from the datastore. This method does not affect the cache. removeFromCache void removeFromCache(Row row)(Code) retrieve public void retrieve(Object object)(Code) This operation is not currently supported. retrieveAll public void retrieveAll(Collection collection)(Code) This operation is not currently supported. retrieveAll public void retrieveAll(Collection collection, boolean dfgOnly)(Code) This operation is not currently supported. retrieveAll public void retrieveAll(Object[] array)(Code) This operation is not currently supported. retrieveAll public void retrieveAll(Object[] array, boolean dfgOnly)(Code) This operation is not currently supported. selectRows Collection selectRows(Selector selector)(Code) Selects the rows from the datastore matching the selection criteria. If no transaction is in progress, but nontransactionalRead is enabled, begins and ends a datastore transaction in order to perform the query. Before returning the collection of rows, this method adds the query results and any extra rows read by the driver to the cache. setIgnoreCache public void setIgnoreCache(boolean ignoreCache)(Code) Sets the value of the ignoreCache flag. Currently this suggestion is given little attention. setMultithreaded public void setMultithreaded(boolean multithreaded)(Code) Indicates that this PersistenceManager will be used in a multithreaded context. Currently this flag is not being used. setUserObject public void setUserObject(Object userObject)(Code) Allows the user to associate an arbitrary object with this InterfaceManager.
