    Description copied from interface: Type
    
    Reconstruct the object from its disassembled state. This method is the reciprocal of Type.disassemble(java.lang.Object, org.hibernate.engine.spi.SessionImplementor, java.lang.Object)
    
    Specified by:
    
    assemble in interface Type

                         throws HibernateException
```
    Description copied from interface: Type
    
    Return a disassembled representation of the object. This is the value Hibernate will use in second level caching, so care should be taken to break values down to their simplest forms; for entities especially, this means breaking them down into their constituent parts.
    
    Specified by:
    
    disassemble in interface Type
    
    Overrides:
    
    disassemble in class AbstractType
    
    Parameters:
    value - the value to cache
    session - the originating session
    owner - optional parent entity object (needed for collections)
    
    Returns:
    the disassembled, deep cloned state
    
    Throws:

  - replace

             Map copyCache)
               throws HibernateException
```
    Description copied from interface: Type
    
    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 Type
    
    Parameters:
    original - the value from the detached entity being merged
    target - the value in the managed entity

    owner - The owner of the value
    copyCache - The cache of already copied/replaced values
    
    Returns:
    the value to be merged
    
    Throws:
    
    HibernateException - An error from Hibernate
  - isEqual

                throws HibernateException
```
    Description copied from interface: Type
    
    Compare two instances of the class mapped by this type for persistence "equality" (equality of persistent state).
    This should always equate to some form of comparison of the value's internal state. As an example, for something like a date the comparison should be based on its internal "time" state based on the specific portion it is meant to represent (timestamp, date, time).
    
    Specified by:
    
    isEqual in interface Type
    
    Overrides:
    
    isEqual in class AbstractType
    
    Parameters:
    x - The first value
    y - The second value
    
    Returns:
    True if there are considered equal (see discussion above).
    
    Throws:
    
    HibernateException - A problem occurred performing the comparison
  - getHashCode
```
public int getHashCode(Object x)
```
    Description copied from interface: Type
    
    Get a hash code, consistent with persistence "equality". Again for most types the normal usage is to delegate to the value's hashCode.
    
    Specified by:
    
    getHashCode in interface Type
    
    Overrides:
    
    getHashCode in class AbstractType
    
    Parameters:
    x - The value for which to retrieve a hash code
    
    Returns:
    The hash code

    Specified by:
    
    getReturnedClass in interface Type
    
    Returns:

    Specified by:
    
    isMutable in interface Type
    
    Returns:
    boolean
  - nullSafeGet
