It may become a performance bottleneck if we fetch all rows form database. 2. Users may want to see one page at a time. Imagine Google showing all pages at once.
1 Talk about pagination concerns Get the search query, talk to business logic to get the data caching the data and search query etc Everybody writes their own pagination logic 2. Even there it’s good enough for simple pages with less data. It doesn’t have the notion of caching the data and no notion on how to handle server side consistently.
Shouldn’t need any interfaces or abstract methods to be implemented by DAO or Service layer 3. Reuse of existing framework like displaytag. No need to reinvent the wheel. At the same time it should be easier for existing users to use this framework. 4. View Independent Show the relationship with making it HTTP independent
Show an example for the same. 2. Problem with legacy code. Don’t want to change the legacy code block. However a problem as catching Exception will catch the runtimeexception also. 3. Created PaginationCacheStore interface and its application level and session level implementation. 4. Needed to remove the frequent access to database. Using Caching framework independent implementation.
Option 1 You can pass this object to displaytag as an usual list, and it will extract paging and sorting information from it.
This is a must when used with partial lists The purpose of this property is for convenience when writing the backend code that actually does the sorting of the data. For example the header link for the column with property id in the sample code above will render a link containing d-(encoded table id)-s=id. If you remove the sortName property from the column the link will instead contain d-(encoded table id)-s=0, which is the index of the column rather than the name. 4. You do this by storing the total list size in a java.lang.Integer object and putting it into some scope available to DisplayTag.
