| org.hibernate.tuple.Tuplizer
| Tuplizer | | public interface Tuplizer (Code) | | A tuplizer defines the contract for things which know how to manage
a particular representation of a piece of data, given that
representation's
org.hibernate.EntityMode (the entity-mode
essentially defining which representation).
If that given piece of data is thought of as a data structure, then a tuplizer
is the thing which knows how to
- create such a data structure appropriately
- extract values from and inject values into such a data structure
For example, a given piece of data might be represented as a POJO class.
Here, it's representation and entity-mode is POJO. Well a tuplizer for POJO
entity-modes would know how to
- create the data structure by calling the POJO's constructor
- extract and inject values through getters/setter, or by direct field access, etc
That same piece of data might also be represented as a DOM structure, using
the tuplizer associated with the DOM4J entity-mode, which would generate instances
of
org.dom4j.Element as the data structure and know how to access the
values as either nested
org.dom4j.Element s or as
org.dom4j.Attribute s.

| Method Summary | |
| public Class | getMappedClass()
Return the pojo class managed by this tuplizer. | | public Object | getPropertyValue(Object entity, int i)
Extract the value of a particular property from the given entity.
Parameters:
entity - The entity from which to extract the property value.
Parameters:
i - The index of the property for which to extract the value. | | public Object[] | getPropertyValues(Object entity)
Extract the current values contained on the given entity.
Parameters:
entity - The entity from which to extract values. | | public Object | instantiate()
Generate a new, empty entity. | | public boolean | isInstance(Object object)
Is the given object considered an instance of the the entity (acconting
for entity-mode) managed by this tuplizer.
Parameters:
object - The object to be checked. | | public void | setPropertyValues(Object entity, Object[] values)
Inject the given values into the given entity. |
| getMappedClass | | public Class getMappedClass()(Code) | | Return the pojo class managed by this tuplizer.
Need to determine how to best handle this for the Tuplizers for EntityModes
other than POJO.
todo : be really nice to not have this here since it is essentially pojo specific...
The persistent class. |
| getPropertyValue | | public Object getPropertyValue(Object entity, int i) throws HibernateException(Code) | | Extract the value of a particular property from the given entity.
Parameters:
entity - The entity from which to extract the property value.
Parameters:
i - The index of the property for which to extract the value. The current value of the given property on the given entity.
throws:
HibernateException - |
| getPropertyValues | | public Object[] getPropertyValues(Object entity) throws HibernateException(Code) | | Extract the current values contained on the given entity.
Parameters:
entity - The entity from which to extract values. The current property values.
throws:
HibernateException - |
| isInstance | | public boolean isInstance(Object object)(Code) | | Is the given object considered an instance of the the entity (acconting
for entity-mode) managed by this tuplizer.
Parameters:
object - The object to be checked. True if the object is considered as an instance of this entitywithin the given mode. |
