Add

properties
...
to

an

already

existing

Replicable
...
entity
...
You
...
have
...
2
...
posibilities.
...
- Make
...
- use
...
- of
...
- the
...
public
...
Map<String,

Object>
...
getMongoProperties(String
...
domain)
...
- .
...
- Use
...
- this
...
- method
...
- if
...
- the
...
- properties
...
- you
...
- add
...
- are
...
- not
...
- common
...
- to
...
- multiple
...
- entities.
...
- If
...
- this
...
- is
...
- the
...
- case
...
- ...
...
- Add
...
- the
...
- properties
...
- in
...
- a
...
- DataSet.
...
- You
...
- can
...
- create
...
- a
...
- separate
...
- one
...
- or
...
- make
...
- use
...
- of
...
- an
...
- already

- existing
...
- one.
...
Examples
...
- are
...
- all
...
- over

- the
...
- place.
...
- For
...
- instance,
...
- take
...
- a
...
- look
...
- at
...
- OpenAcdAgent
...
- .
...
- It
...
- has
...
- a
...
- bunch
...
- of
...
- "proprietary"

- properties
...
- and

- also

- some

Make

an

entity

Replicable
...
- you

- must
...
- make
...
- sure
...
- the
...
- entity
...
- implements
...
- Replicable
...
- interface.
...
- Implement
...
- all
...
- methods
...
- with
...
- relevant
...
- info.
...
- make
...
- sure
...
- the
...
- replication
...
- is
...
- triggered
...
- when
...
- saving
...
- and
...
- deleting.
...
- One
...
- thing
...
- to
...
- take
...
- into
...
- account
...
- is
...
- that
...
- the
...
- replication
...
- is
...
- not
...
- triggered
...
- if
...
- the
...
- save
...
- method
...
- is
...
- called
...
- something
...
- other
...
- than
...
- saveObject(Object)
...
- (replace
...
- Object
...
- with
...
- any
...
- name),
...
- because
...
- only
...
- the
...
- methods
...
- with
...
- that
...
- name
...
- are
...
- intercepted.
...
- (Similar
...
- with
...
- delete.)
...
- Another
...
- option
...
- is
...
- to
...
- publish
...
- an
...
- event,
...
- but
...
- the
...
- recommended
...
- way
...
- is
...
- the
...
- interceptor
...
- way.
...
- make
...
- sure
...
- the
...
- entities
...
- are
...
- retrieved
...
- by
...
- an
...
- ReplicableProvider
...
- .
...
- The
...
- recommended
...
- way
...
- to
...
- do
...
- that
...
- is
...
- to
...
- create
...
- a
...
- separate
...
- ReplicableProvider
...
- implementation
...
- to
