See: Custom Ant Selectors for more details.

Allows a JoSQL WHERE clause to be applied to each file passed to the selector JoSQLAntFileSelector.isSelected(File,String,File) .

An obvious question to ask here is "why do I need this when Ant has lots of custom file selectors". Well, in short, you don't "need" this selector, but I've found that trying to remember all the custom elements and their attributes can be painful and doesn't give me all the power needed to select the files I want.

Example:

 <%@ page import="java.util.Arrays" %>
 <%@ page import="java.io.File" %>
 <%@ tablib prefix="josql" uri="josqltaglib" %>
 <josql:query inputList='<%= Arrays.asList (new File ("/home/me/").listFiles ()) %>'
 results="queryResults">
 SELECT *
 FROM   java.io.File
 WHERE  name = '.bashrc'
 </josql:query>
 

The body of the tag is taken as the statement to execute.

Note: this class deliberately does NOT extend Query since doing so would then prevent the query from being released via the JoSQLJSPQueryTag.release() method.

The following attributes are supported:

• inputList - specifies the name of an attribute that holds the List of objects to execute the JoSQL statement against, or is the List of objects.

One limitation here is that the SQL query must return columns rather than the objects since the values need to be mapped by the renderer and editor.
