Field Detail

SQL_TYPES

private static final int[] SQL_TYPES

Constructor Detail

MonetaryAmountUserType

public MonetaryAmountUserType()

Method Detail

sqlTypes

public int[] sqlTypes()

Description copied from interface: org.hibernate.usertype.UserType

Return the SQL type codes for the columns mapped by this type. The codes are defined on java.sql.Types.

Specified by:

sqlTypes in interface org.hibernate.usertype.UserType

---

returnedClass

public java.lang.Class returnedClass()

Description copied from interface: org.hibernate.usertype.UserType

The class returned by nullSafeGet().

Specified by:

returnedClass in interface org.hibernate.usertype.UserType

---

isMutable

public boolean isMutable()

Description copied from interface: org.hibernate.usertype.UserType

Are objects of this type mutable?

Specified by:

isMutable in interface org.hibernate.usertype.UserType

---

deepCopy

public java.lang.Object deepCopy(java.lang.Object value)

Description copied from interface: org.hibernate.usertype.UserType

Return a deep copy of the persistent state, stopping at entities and at collections. It is not necessary to copy immutable objects, or null values, in which case it is safe to simply return the argument.

Specified by:

deepCopy in interface org.hibernate.usertype.UserType

---

equals

public boolean equals(java.lang.Object x,
                      java.lang.Object y)

Description copied from interface: org.hibernate.usertype.UserType

Compare two instances of the class mapped by this type for persistence "equality". Equality of the persistent state.

Specified by:

equals in interface org.hibernate.usertype.UserType

---

nullSafeGet

public java.lang.Object nullSafeGet(java.sql.ResultSet resultSet,
                                    java.lang.String[] names,
                                    java.lang.Object owner)
                             throws org.hibernate.HibernateException,
                                    java.sql.SQLException

Description copied from interface: org.hibernate.usertype.UserType

Retrieve an instance of the mapped class from a JDBC resultset. Implementors should handle possibility of null values.

Specified by:

nullSafeGet in interface org.hibernate.usertype.UserType

---

nullSafeSet

public void nullSafeSet(java.sql.PreparedStatement statement,
                        java.lang.Object value,
                        int index)
                 throws org.hibernate.HibernateException,
                        java.sql.SQLException

Description copied from interface: org.hibernate.usertype.UserType

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.

Specified by:

nullSafeSet in interface org.hibernate.usertype.UserType

---

disassemble

public java.io.Serializable disassemble(java.lang.Object value)
                                 throws org.hibernate.HibernateException

Description copied from interface: org.hibernate.usertype.UserType

Transform the object into its cacheable representation. At the very least this method should perform a deep copy if the type is mutable. That may not be enough for some implementations, however; for example, associations must be cached as identifier values. (optional operation)

Specified by:

disassemble in interface org.hibernate.usertype.UserType

---

assemble

public java.lang.Object assemble(java.io.Serializable cached,
                                 java.lang.Object owner)
                          throws org.hibernate.HibernateException

Description copied from interface: org.hibernate.usertype.UserType

Reconstruct an object from the cacheable representation. At the very least this method should perform a deep copy if the type is mutable. (optional operation)

Specified by:

assemble in interface org.hibernate.usertype.UserType

---

replace

public java.lang.Object replace(java.lang.Object original,
                                java.lang.Object target,
                                java.lang.Object owner)
                         throws org.hibernate.HibernateException

Description copied from interface: org.hibernate.usertype.UserType

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. For objects with component values, it might make sense to recursively replace component values.

Specified by:

replace in interface org.hibernate.usertype.UserType

---

hashCode

public int hashCode(java.lang.Object x)
             throws org.hibernate.HibernateException

Description copied from interface: org.hibernate.usertype.UserType

Get a hashcode for the instance, consistent with persistence "equality"

Specified by:

hashCode in interface org.hibernate.usertype.UserType
