org.hibernate.classic
Interface Session

All Superinterfaces:
Serializable, Session
All Known Implementing Classes:
SessionImpl
public interface Session
extends Session

An extension of the Session API, including all deprecated methods from Hibernate2. This interface is provided to allow easier migration of existing applications. New code should use org.hibernate.Session.

                        throws HibernateException
Deprecated. use Session.merge(Object)

Copy the state of the given object onto the persistent object with the same identifier. If there is no persistent instance currently associated with the session, it will be loaded. Return the persistent instance. If the given instance is unsaved or does not exist in the database, save it and return it as a newly persistent instance. Otherwise, the given instance does not become associated with the session.

Parameters:
object - a transient instance with state to be copied
Returns:
an updated persistent instance
Throws:
HibernateException

saveOrUpdateCopy

                        throws HibernateException
Deprecated. with no replacement

Copy the state of the given object onto the persistent object with the given identifier. If there is no persistent instance currently associated with the session, it will be loaded. Return the persistent instance. If there is no database row with the given identifier, save the given instance and return it as a newly persistent instance. Otherwise, the given instance does not become associated with the session.

Parameters:
object - a persistent or transient instance with state to be copied
id - the identifier of the instance to copy to
Returns:
an updated persistent instance
Throws:
HibernateException

                        throws HibernateException
Deprecated. use Session.merge(String, Object)

Copy the state of the given object onto the persistent object with the same identifier. If there is no persistent instance currently associated with the session, it will be loaded. Return the persistent instance. If the given instance is unsaved or does not exist in the database, save it and return it as a newly persistent instance. Otherwise, the given instance does not become associated with the session.

Parameters:
object - a transient instance with state to be copied
Returns:

Copy the state of the given object onto the persistent object with the given identifier. If there is no persistent instance currently associated with the session, it will be loaded. Return the persistent instance. If there is no database row with the given identifier, save the given instance and return it as a newly persistent instance. Otherwise, the given instance does not become associated with the session.

Parameters:

find

public List find(String query)
          throws HibernateException
Deprecated. use Session.createQuery(java.lang.String).Query.list()

Execute a query.

Parameters:
query - a query expressed in Hibernate's query language
Returns:
a distinct list of instances (or arrays of instances)
Throws:
HibernateException

find

public List find(String query,
                 Object value,
                 Type type)
          throws HibernateException
Deprecated. use Session.createQuery(java.lang.String).setXYZ.Query.list()

Execute a query with bind parameters, binding a value to a "?" parameter in the query string.

Parameters:
query - the query string
value - a value to be bound to a "?" placeholder (JDBC IN parameter).
type - the Hibernate type of the value
Returns:
a distinct list of instances (or arrays of instances)
Throws:
HibernateException
See Also:
for access to Type instances

find

public List find(String query,
                 Object[] values,
                 Type[] types)
          throws HibernateException
Deprecated. use Session.createQuery(java.lang.String).setXYZ.Query.list()

Execute a query with bind parameters, binding an array of values to "?" parameters in the query string.

Parameters:
query - the query string
values - an array of values to be bound to the "?" placeholders (JDBC IN parameters).
types - an array of Hibernate types of the values
Returns:
a distinct list of instances
Throws:
HibernateException
See Also:

iterate

public Iterator iterate(String query)
                 throws HibernateException
Deprecated. use Session.createQuery(java.lang.String).Query.iterate()

Execute a query and return the results in an iterator. If the query has multiple return values, values will be returned in an array of type Object[].

Entities returned as results are initialized on demand. The first SQL query returns identifiers only. So iterate() is usually a less efficient way to retrieve objects than find().

Parameters:
query - the query string
Returns:
an iterator
Throws:
HibernateException

iterate

public Iterator iterate(String query,
                        Object value,

                 throws HibernateException
Deprecated. use Session.createQuery(java.lang.String).setXYZ.Query.iterate()

Execute a query and return the results in an iterator. Write the given value to "?" in the query string. If the query has multiple return values, values will be returned in an array of type Object[].

Entities returned as results are initialized on demand. The first SQL query returns identifiers only. So iterate() is usually a less efficient way to retrieve objects than find().

Parameters:
query - the query string
value - a value to be witten to a "?" placeholder in the query string
type - the hibernate type of value
Returns:
an iterator
Throws:
HibernateException

iterate

public Iterator iterate(String query,
                        Object[] values,
                        Type[] types)
                 throws HibernateException
Deprecated. use Session.createQuery(java.lang.String).setXYZ.Query.iterate()

Execute a query and return the results in an iterator. Write the given values to "?" in the query string. If the query has multiple return values, values will be returned in an array of type Object[].

Entities returned as results are initialized on demand. The first SQL query returns identifiers only. So iterate() is usually a less efficient way to retrieve objects than find().

Parameters:
query - the query string
values - a list of values to be written to "?" placeholders in the query
types - a list of Hibernate types of the values
Returns:
an iterator
Throws:
HibernateException

public Collection filter(Object collection,
                         String filter)
                  throws HibernateException
Deprecated. use Session.createFilter(Object, String).Query.list()

Apply a filter to a persistent collection. A filter is a Hibernate query that may refer to this, the collection element. Filters allow efficient access to very large lazy collections. (Executing the filter does not initialize the collection.)

Parameters:
collection - a persistent collection to filter
filter - a filter query string
Returns:
Collection the resulting collection
Throws:
HibernateException

filter

public Collection filter(Object collection,
                         String filter,
                         Object value,
                         Type type)
                  throws HibernateException
Deprecated. use Session.createFilter(Object, String).setXYZ.Query.list()

Apply a filter to a persistent collection. A filter is a Hibernate query that may refer to this, the collection element.

Parameters:
collection - a persistent collection to filter
filter - a filter query string
value - a value to be witten to a "?" placeholder in the query string
type - the hibernate type of value
Returns:
Collection
Throws:
HibernateException

filter

public Collection filter(Object collection,
                         String filter,

                         Type[] types)
                  throws HibernateException
Deprecated. use Session.createFilter(Object, String).setXYZ.Query.list()

Apply a filter to a persistent collection. Bind the given parameters to "?" placeholders. A filter is a Hibernate query that may refer to this, the collection element.

Parameters:
collection - a persistent collection to filter
filter - a filter query string
values - a list of values to be written to "?" placeholders in the query
types - a list of Hibernate types of the values

Returns:
the number of instances deleted
Throws:
HibernateException
