Changing the primary type of a node?

[Sridhar Raman <sr...@gmail.com>]

Hi

Is it possible to change the primary type of a node programmatically?  Or is
the only option is to create a new node with the new primary type, and
transfer the contents?

Thanks,
Sridhar

I guess the cleanest approach would be to re-evaluate the type
constraints during the next save() call. This way the client can
perform any modifications necessary to make the node meet the
constraints of the new type.

there are basically the same requirements as for the Node.addMixin()
and .removeMixin() methods as those change the effective type of a node.

the resulting effective node type must be compliant with the node type
constraints defined on its parent.

Any idea how that is going to work?
The types must be compatible somehow?

currently there's no easy programmatic way of changing the primary type
of a node. jcr 2.0 (jsr-283) will include a new method
Node.setPrimaryType(String)
but for the time being you'll have to use some workaround.
