-<P>
-<p>Abstract view tool for doing request-based pagination of
- items in an a list.
- </p>
- <p><b>Usage:</b><br>
- To use this class, you must extend it and implement
- the setup(HttpServletRequest) method.
- <p>
- The setup(HttpServletRequest) method ought to extract
- from the current request the current list index and,
- optionally, the number of items to display per page.
- Upon extracting these parameters, they should be set using
- the provided setIndex(int) and setItemsPerPage(int) methods.
- A simple implementation would be:
- <pre>
- public void setup(HttpServletRequest req)
- {
- ParameterParser pp = new ParameterParser(req);
- setIndex(pp.getInt("index", 0));
- setItemsPerPage(pp.getInt("show", DEFAULT_ITEMS_PER_PAGE));
- }
- </pre>
- You can also set the list of items to be paged at this point
- using the setItems(List) method, or you can always set the
- item list at another point (even from within the template).
- </p>
- <p>
- Here's an example of how your subclass would be used in a template:
- <pre>
- #if( $pager.hasItems() )
- Showing $!pager.pageDescription<br>
- #set( $i = $pager.index )
- #foreach( $item in $pager.page )
- ${i}. $!item <br>
- #set( $i = $i + 1 )
- #end
- <br>
- #if ( $pager.pagesAvailable > 1 )
- #set( $pagelink = $link.setRelative('pager.vm').addQueryData("find",$!pager.criteria).addQueryData("show",$!pager.itemsPerPage) )
- #if( $pager.prevIndex )
- <a href="$pagelink.addQueryData('index',$!pager.prevIndex)">Prev</a>
- #end
- #foreach( $index in $pager.slip )
- #if( $index == $pager.index )
- <b>$pager.pageNumber</b>
- #else
- <a href="$pagelink.addQueryData('index',$!index)">$!pager.getPageNumber($index)</a>
- #end
- #end
- #if( $pager.nextIndex )
- <a href="$pagelink.addQueryData('index',$!pager.nextIndex)">Next</a>
- #end
- #end
- #else
- No items in list.
- #end
- </pre>
-
- The output of this might look like:<br><br>
- Showing 1-5 of 8<br>
- 1. foo<br>
- 2. bar<br>
- 3. blah<br>
- 4. woogie<br>
- 5. baz<br><br>
- <b>1</b> <a href="">2</a> <a href="">Next</a>
- </p>
- <p>
- <b>Example toolbox.xml configuration:</b>
- <pre><tool>
- <key>pager</key>
- <scope>request</scope>
- <class>com.foo.tools.MyPagerTool</class>
- </tool>

+
+<P>
+<p>Abstract view tool for doing request-based pagination of
+ items in an a list.
+ </p>
+ <p><b>Usage:</b><br>
+ To use this class, you must extend it and implement
+ the setup(HttpServletRequest) method.
+ <p>
+ The setup(HttpServletRequest) method ought to extract
+ from the current request the current list index and,
+ optionally, the number of items to display per page.
+ Upon extracting these parameters, they should be set using
+ the provided setIndex(int) and setItemsPerPage(int) methods.
+ A simple implementation would be:
+ <pre>
+ public void setup(HttpServletRequest req)
+ {
+ ParameterParser pp = new ParameterParser(req);
+ setIndex(pp.getInt("index", 0));
+ setItemsPerPage(pp.getInt("show", DEFAULT_ITEMS_PER_PAGE));
+ }
+ </pre>
+ You can also set the list of items to be paged at this point
+ using the setItems(List) method, or you can always set the
+ item list at another point (even from within the template).
+ </p>
+ <p>
+ Here's an example of how your subclass would be used in a template:
+ <pre>
+ #if( $pager.hasItems() )
+ Showing $!pager.pageDescription<br>
+ #set( $i = $pager.index )
+ #foreach( $item in $pager.page )
+ ${i}. $!item <br>
+ #set( $i = $i + 1 )
+ #end
+ <br>
+ #if ( $pager.pagesAvailable > 1 )
+ #set( $pagelink = $link.self.param("show",$!pager.itemsPerPage) )
+ #if( $pager.prevIndex )
+ <a href="$pagelink.param('index',$!pager.prevIndex)">Prev</a>
+ #end
+ #foreach( $index in $pager.slip )
+ #if( $index == $pager.index )
+ <b>$pager.pageNumber</b>
+ #else
+ <a href="$pagelink.param('index',$!index)">$!pager.getPageNumber($index)</a>
+ #end
+ #end
+ #if( $pager.nextIndex )
+ <a href="$pagelink.param('index',$!pager.nextIndex)">Next</a>
+ #end
+ #end
+ #else
+ No items in list.
+ #end
+ </pre>
+
+ The output of this might look like:<br><br>
+ Showing 1-5 of 8<br>
+ 1. foo<br>
+ 2. bar<br>
+ 3. blah<br>
+ 4. woogie<br>
+ 5. baz<br><br>
+ <b>1</b> <a href="">2</a> <a href="">Next</a>
+ </p>
+ <p>
+ <b>Example toolbox.xml configuration:</b>

+ <key>pager</key>
+ <scope>request</scope>
