The SortFilterService is used to keep track of sorts and
filters query parameters that are stored on the URL. |
This package defines a set of JSP tag extensions providing repeating databinding support.
The tags in this package fall into one of two categories:
The second tagset consists of repeating tags that are used to render data sets into a JSP page. A repeating tag is a tag that, given a data set, renders each item or a subset of items in the data set into a page. The top level tags in these tag sets are:
container
and referencing the current item with the syntax container.item
. The Repeater tag
can also be used in a more structured way where it can render a header, item, and footer where the
item is rendered once for each item in the data set. Many different types of data sets can
be rendered by these tags including Java Collections, Maps, and arrays. For each of these tags, the
dataSource
attribute is used to reference a data set to render.
A final repeating, databinding tag set is the Grid tag set, which is used to render
data from a javax.sql.RowSet
object. A RowSet is a disconnected data set that
contains data from a relational database, and the Grid tag set provides the ability
to page, sort, and filter this data. The Grid tag does not render its item using
other NetUI HTML tags, rather the Grid renders using its child Columns and
specific column tags that render UI for each cell of each record in the RowSet.
The Repeater and Grid tags are complex tags that render their bodies many times but only render part of their bodies each time. These tags use a state machine and a "render state" that is exposed to tags that are members of the Repeater tag set and Grid tag sets respectively. Tags that unerstand these states render in the appropriate state in order to produce the markup that is written to a JSP pages.
