Usage

From source file:org.apache.struts.chain.servlet.TilesPreProcessor.java

/**
 * <p>If the current <code>ForwardConfig</code> is using "tiles",
 * perform necessary pre-processing to set up the <code>TilesContext</code>
 * and substitute a new <code>ForwardConfig</code> which is understandable
 * to a <code>RequestDispatcher</code>.</p>
 *
 * <p>Note that if the command finds a previously existing
 * <code>ComponentContext</code> in the request, then it
 * infers that it has been called from within another tile,
 * so instead of changing the <code>ForwardConfig</code> in the chain
 * <code>Context</code>, the command uses <code>RequestDispatcher</code>
 * to <em>include</em> the tile, and returns true, indicating that the processing
 * chain is complete.</p>//from   ww  w . jav  a 2  s.com
 *
 * @param context The <code>Context</code> for the current request
 *
 * @return <code>false</code> in most cases, but true if we determine
 * that we're processing in "include" mode.
