Re: [Fwd: RE: [Hibernate] @Fetch]
Hi, I don't fully understand you. My plan was to add at least org.hibernate.annotations.Lazy and org.hibernate.annotations.Fetch They will keep the standard/extension separation clean.

Re: [Hibernate] Componets equals null
I was trying to write it as UserType.
But I couldn't obtain the same functionality that I have with a
hibernate component, because I find no way to implement an UserType that
some of his properties be part of a manytoone or onetomany relation.

I think that this behavior is more natural to final user as its follow
the minimal surprise concept. Why if the component has all nulls
properties and in the db all the fields were null, hibernate generates
and update?
This is the problem, none of the solutions will be symmetric.
Hibernate chooses that a null value means null in the db and vice versa.
You can write a custom user type if you want a behavior that instantiates
a component with null values instead.

you should probably use a UserType to code such application semantic.

Hi,
I made a simple modification in the ComponentType class to
consider null component equals to a components with all his
properties nulls.
I do this to address 2 problems I have:
1. For simplicity in all entities, when a components is null the
getters builds a new instance and then returning it. But with
this
pattern hibernate detects this entities dirty and generates
updates to the db that aren't need.
2. I have a very long process where I traverse a long dataset make
some computations and generates very few result. This process
always generates OutofMemory exception because hibernate detects
to many dirty entities (one solution it to flush the session
often, but I don't want to update the entity and the process with
the spurious updates is slower)

Some code to explain better:
/**
* return the properties' values if the components != null, or and
array of null values.
*/
private Object[] getPropertyValuesArray(Object component,
EntityMode entityMode) {
if (component == null) {
return new Object[propertyTypes.length];
} else {
return getPropertyValues(component, entityMode);
}
}
/**
* And somethig similar for isDirty, isSame
*/
public boolean isEqual(Object x, Object y, EntityMode
entityMode) throws HibernateException {
if ( x == y ) return true;
//if ( x == null || y == null ) return false;
Object[] xvalues = getPropertyValuesArray(x, entityMode);
Object[] yvalues = getPropertyValuesArray(y, entityMode);
for ( int i = 0; i propertySpan; i++ ) {
if ( !propertyTypes[i].isEqual( xvalues[i], yvalues[i],
entityMode ) ) return false;
}
return true;
}

RE: [Fwd: RE: [Hibernate] @Fetch]
OK this is what I would want to happen. +1 for completing the extensions to be much closer to what is available in the hbm mapping side. As far as separating Entity V Collection - Maybe should be separated to allow more accurate IDE auto complete and static compliation checking to occur. I have not looked at Java6 to see if validation of annotations will help in this area. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Emmanuel Bernard Sent: Monday, 13 March 2006 7:32 PM Cc: Hibernate development Subject: Re: [Fwd: RE: [Hibernate] @Fetch] Hi, I don't fully understand you.
