Methods Summary
public java.lang.Object	assemble(java.io.Serializable cached, org.hibernate.engine.SessionImplementor session, java.lang.Object owner) Reconstruct an object from the cacheable representation. At the very least this method should perform a deep copy. (optional operation) param cached the object to be cached param session param owner the owner of the cached object return a reconstructed object from the cachable representation throws HibernateException
public java.lang.Object	deepCopy(java.lang.Object value) Return a deep copy of the persistent state, stopping at entities and at collections. param value generally a collection element or entity field return Object a copy throws HibernateException
public java.io.Serializable	disassemble(java.lang.Object value, org.hibernate.engine.SessionImplementor session) Transform the object into its cacheable representation. At the very least this method should perform a deep copy. That may not be enough for some implementations, however; for example, associations must be cached as identifier values. (optional operation) param value the object to be cached param session return a cachable representation of the object throws HibernateException
public boolean	equals(java.lang.Object x, java.lang.Object y) Compare two instances of the class mapped by this type for persistence "equality". Equality of the persistent state. param x param y return boolean throws HibernateException
public java.lang.String[]	getPropertyNames() Get the "property names" that may be used in a query. return an array of "property names"
public org.hibernate.type.Type[]	getPropertyTypes() Get the corresponding "property types". return an array of Hibernate types
public java.lang.Object	getPropertyValue(java.lang.Object component, int property) Get the value of a property. param component an instance of class mapped by this "type" param property return the property value throws HibernateException
public int	hashCode(java.lang.Object x) Get a hashcode for the instance, consistent with persistence "equality"
public boolean	isMutable() Check if objects of this type mutable. return boolean
public java.lang.Object	nullSafeGet(java.sql.ResultSet rs, java.lang.String[] names, org.hibernate.engine.SessionImplementor session, java.lang.Object owner) Retrieve an instance of the mapped class from a JDBC resultset. Implementors should handle possibility of null values. param rs a JDBC result set param names the column names param session param owner the containing entity return Object throws HibernateException throws SQLException
public void	nullSafeSet(java.sql.PreparedStatement st, java.lang.Object value, int index, org.hibernate.engine.SessionImplementor session) Write an instance of the mapped class to a prepared statement. Implementors should handle possibility of null values. A multi-column type should be written to parameters starting from index. param st a JDBC prepared statement param value the object to write param index statement parameter index param session throws HibernateException throws SQLException
public java.lang.Object	replace(java.lang.Object original, java.lang.Object target, org.hibernate.engine.SessionImplementor session, java.lang.Object owner) During merge, replace the existing (target) value in the entity we are merging to with a new (original) value from the detached entity we are merging. For immutable objects, or null values, it is safe to simply return the first parameter. For mutable objects, it is safe to return a copy of the first parameter. However, since composite user types often define component values, it might make sense to recursively replace component values in the target object. param original param target param session param owner return throws HibernateException
public java.lang.Class	returnedClass() The class returned by nullSafeGet(). return Class
public void	setPropertyValue(java.lang.Object component, int property, java.lang.Object value) Set the value of a property. param component an instance of class mapped by this "type" param property param value the value to set throws HibernateException
