| SingleEMTestCase | | abstract public class SingleEMTestCase extends SingleEMFTestCase (Code) | | A base test case that can be used to easily test scenarios where there
is only a single EntityManager at any given time.

| Method Summary | |
| protected boolean | begin()
Start a new transaction if there isn't currently one active. | | protected boolean | close()
Closes the current EntityManager if it is open. | | protected boolean | commit()
Commit the current transaction, if it is active. | | protected List<E> | find(Class<E> c, String q, Object... params)
Returns a list of all instances of the specific class in the database. | | protected List<E> | find(Class<E> c)
Returns a list of all instances of the specific class in the database. | | protected void | persist(Object... obs)
Persist all of the instances. | | protected OpenJPAQuery | query(String str)
Creates a query in the current EntityManager with the specified string. | | protected OpenJPAQuery | query(Class c, String str, Object... params)
Create a query against the specified class, which will be aliased
as "x". | | protected void | remove(Object... obs)
Delete all of the instances. | | protected void | reset()
Clear the current EntityManager and re-initialize it. | | protected boolean | rollback()
Rollback the current transaction, if it is active. | | public void | setUp()
| | public void | setUp(Object... props)
| | public void | tearDown()
|
| begin | | protected boolean begin()(Code) | | Start a new transaction if there isn't currently one active.
true if a transaction was started, false if one already existed |
| close | | protected boolean close()(Code) | | Closes the current EntityManager if it is open.
false if the EntityManager was already closed. |
| commit | | protected boolean commit()(Code) | | Commit the current transaction, if it is active.
true if the transaction was committed |
| find | | protected List<E> find(Class<E> c)(Code) | | Returns a list of all instances of the specific class in the database.
|
| persist | | protected void persist(Object... obs)(Code) | | Persist all of the instances.
If no transaction is running, then one will be started and committed.
Otherwise, the operation will take place in the current transaction.
|
| query | | protected OpenJPAQuery query(String str)(Code) | | Creates a query in the current EntityManager with the specified string.
|
| query | | protected OpenJPAQuery query(Class c, String str, Object... params)(Code) | | Create a query against the specified class, which will be aliased
as "x". For example, query(Person.class, "where x.age = 21") will
create the query "select x from Person x where x.age = 21".
Parameters:
c - the class to query against
Parameters:
str - the query suffix
Parameters:
params - the parameters, if any the Query object |
| remove | | protected void remove(Object... obs)(Code) | | Delete all of the instances.
If no transaction is running, then one will be started and committed.
Otherwise, the operation will take place in the current transaction.
|
| reset | | protected void reset()(Code) | | Clear the current EntityManager and re-initialize it.
|
| rollback | | protected boolean rollback()(Code) | | Rollback the current transaction, if it is active.
true if the transaction was rolled back |
| setUp | | public void setUp()(Code) | | |
