Parameters:

itemId -

addItems

public void addItems(List itemsToAdd,
                     String locationItemId)

add a new List of content Ids (mbaseIds) after the given ItemId into the itemIds of this Page.

Parameters:

itemsToAdd - (List of mbase ids/String)

locationItemId -

instantiateDynamicItems

public void instantiateDynamicItems(String userId)

Currently all the dynamicItem will be treated as non-instantiated, because the execution of part of kinds of dynamicItem occurs no more in logical level but in presentation level. We just instance them to a link-like text item, then the presentation part will worry about the execution of such link. This method instantiated the DynamicItems on the Page. All items in this Page will be checked. There are 2 cases:

• 1. If the item is a dynamic one, if true, then it will be executed with help of the method instanceDynamicItem() from DynamicItem. The result should be packed in a list and it will be analysed here and saved to the resul list.
• 2. If the item is a normal mbase reference, it will be simply saved in result list.

All the dynamicItems will be only instantiated once, on other word, they will be executed once before the user see the page and only the result will be shown to the user. Meanwhile the result will be saved and the omgroup from the OJDocument will be updated accordingly.

Parameters:

userId -

dynamicItemWasDisplayed

public boolean dynamicItemWasDisplayed()

Returns:

Returns true if the dynamic items on this page were displayed

setDynamicItemWasDisplayed

public void setDynamicItemWasDisplayed(boolean flag)

Parameters:

dynamicItemWasDisplayed - The dynamicItemWasDisplayed to set.

containsDynamicTask

public boolean containsDynamicTask()

Returns:

Returns true, if the page contains a dynamic task

clone

public Object clone()
             throws CloneNotSupportedException

Overrides:
