public void lock()
Row
For a View row, this method calls lock() on each Entity row that makes up the View row.
lock
in interface Row
public void remove()
Row
If this method is invoked on a View row or an Entity row, and if the
current concurrency control mode is
,
this method first locks the Entity row(s), and then removes the
Entity row(s). Thus, this method may throw the same
exceptions as Transaction.LOCK_PESSIMISTIC
method.
Row.lock()
remove
in interface Row
public void removeFromCollection()
Row
This method differs from
in that
it just removes the row from the collection. It does not
remove the underlying Entity row(s) or database row(s).
However, once the row is removed, it cannot be used any more.
If you want to remove the row from the collection and insert it elsewhere,
call Row.remove()
.

public void removeAndRetain()
Row
This method differs from
in that
it just removes the row from the collection. It does not
remove the underlying Entity row(s) or database row(s).
Row.remove()
This method also differs from
in that after the row is removed from the collection, it can be inserted
back into the collection at another location.

constants for further information.
refresh
in interface Row
refreshMode
- the refresh mode.public boolean isAttributeUpdateable(int index)
Row
false
if the attribute is read-only and true
if it is updateable.
The following logic is used for determining if the attribute is updateable. If this attribute for a View row and is one which is mapped to an Entity Attribute, and if the Entity base is marked as read-only in the View Object, the attribute is read-only.
If the Entity base is marked updateable, a check is made to see if the the current user has updateable privilege on the underlying Entity row. If not, the attribute is read-only.
After this, we check the View Object's Attribute Definition.
If the Attribute Definition indicates that it is READONLY
, this
method returns false
(read-only). If the Attribute
Definition says UPDATEABLE
, it drops to the Entity level
to determine if the Entity level Attribute Definition says it is
updateable. If the attribute is UPDATEABLE_WHILE_NEW
We check to see if the 'row' is new or not. (If this attribute comes
from an Entity Row, the 'row' is the Entity Row. Otherwise, the 'row'
is the View Row.) If the row is new, the attribute is updateable.

in interface Row
true
if the row is dead.public void setNewRowState(byte state)
Row
This method should be used to create a row and then to mark it temporary (STATUS_INITIALIZED) so that an app can use the created Row to fill UIs like Table UIs with valid default values for rows. Then when the Row values are updated, UIs should once again call this method to turn the Row into new (STATUS_NEW) state before any setAttribute calls on the Row, so that the changes are validated and posted.
When a created row is in STATUS_NEW (by default) state and this method is called to turn the row in to STATUS_INITIALIZED, all updateable entities that this row comprises of, de=registers themselves from their respective transaction and validation managers. Assocation and ViewLink finders will not find/include these rows. Only the collection into which this row was inserted into will contain a reference to this row and when that collection is re-executed this row cannot be reached via the framework. To include this row again an app should call this method again with STATUS_NEW as the method-argument
When this row is in STATUS_INITIALIZED state and this method is called with STATUS_NEW state then, this new row is added back into it's relevant transaction and validation manager and will then participate in validation, transaction cycles.
Note that incase of composition if a master/detail hierarchy is being created with the intention of making them temporary (STATUS_INITIALIZED) then the logic should be: Create Master row, insert Master row into a collection, create Detail row insert detail row into a relevant collection, make detail row initialized, create/insert/change-to-initialized more detail rows and at the end set the master row as initialized.

implement this method to render
data in XML.
Use this method whenever data is required in XML format, either to present a UI (after converting XML data into some HTTP format using a stylesheet) or to pass the data as payload for messages via JMS.
The options parameter represents a set of bit flags that will control the writeXML behavior. The following bit flags have been defined:
EntityImpl
. The voAttrMap parameter represents in a hashmap, the mapping between a given ViewObject's definition type and the corresponding Attributes/accessors to render. A null entry in the hashmap means, render all attributes and accessors of that viewobject type.

The depthcount parameter represents to what level the rendering should recurse. A depthcount of zero (0) means do not traverse any View Links while rendering. One (1) means traverse the View Links on this object but no View Links thereafter, and so on.
