Method Details

supportsVersioning

public boolean supportsVersioning()

Description copied from interface: IPageStore

Is versioning of pages supported, i.e. when an altered page instance has been stored in this store, can the previous state of that page still be retrieved under its former page id. Most implementations achieve this by keeping a copy of the page instance, e.g. by means of serialization.

Specified by:

supportsVersioning in interface IPageStore

canBeAsynchronous

public boolean canBeAsynchronous(IPageContext context)

Description copied from interface: IPageStore

This method is called by AsynchronousPageStore before any attempt to call IPageStore.addPage(IPageContext, IManageablePage) asynchronously.

A page store returning true must immediately access all required values from the context, since no additional values can be accessed when IPageStore.addPage(IPageContext, IManageablePage) is called asynchronously afterwards.

Specified by:

canBeAsynchronous in interface IPageStore

Returns:

whether IPageStore.addPage(IPageContext, IManageablePage) may be called asynchronously, default is false

addPage

public void addPage(IPageContext context,
 IManageablePage page)

Description copied from interface: IPageStore

Stores the page-

Specified by:

removePage

public void removePage(IPageContext context,
 IManageablePage page)

Description copied from interface: IPageStore

Removes a page from storage.

Specified by:

Parameters:

removeAllPages

public void removeAllPages(IPageContext context)

Description copied from interface: IPageStore

All pages should be removed from storage for the given context.

Specified by:

removeAllPages in interface IPageStore

Parameters:

getPage

public IManageablePage getPage(IPageContext context,
 int id)

Description copied from interface: IPageStore
