org.zkoss.zkplus.liferay.JQueryRenderPatch

org.zkoss.zkplus.liferay.NonRootContextJQueryRenderPatch

All Implemented Interfaces:

PageRenderPatch

public class NonRootContextJQueryRenderPatch
extends JQueryRenderPatch

Used to patch the rendering result of a ZK portlet for Liferay. When using ZK portlets with Liferay under non root context, we have to add a JSESSIONID under root(/) path.

To use it, you have to specify a library property called ""org.zkoss.zk.portlet.PageRenderPatch.class" with this class's name ("org.zkoss.zkplus.liferay.NonRootContextJQueryRenderPatch").

Method Detail

beforeRender

public java.io.Writer beforeRender(RequestInfo reqInfo)

Description copied from class: JQueryRenderPatch

It returns an instance of StringWriter if JQueryRenderPatch.getDelay() is non-negative, or null if negative (means no patch).

Specified by:

beforeRender in interface PageRenderPatch

Overrides:

beforeRender in class JQueryRenderPatch

Parameters:

reqInfo - the request information

Returns:

null if no need of patch, or a writer if the patch is required. The writer will be used to hold the rendering result of the portlet. Thus, you can process it later in PageRenderPatch.patchRender(org.zkoss.zk.ui.sys.RequestInfo, org.zkoss.zk.ui.Page, java.io.Writer, java.io.Writer) (so the writer is usually an instance of StringWriter).

patchRender

public void patchRender(RequestInfo reqInfo,
                        Page page,
                        java.io.Writer result,
                        java.io.Writer out)
                 throws java.io.IOException

Description copied from interface: PageRenderPatch

Called after rendering to patch the result. If PageRenderPatch.beforeRender(org.zkoss.zk.ui.sys.RequestInfo) returns null, this method won't be called since nothing to patch.

If PageRenderPatch.beforeRender(org.zkoss.zk.ui.sys.RequestInfo) returns a writer, the writer will become the result argument.

Specified by:

patchRender in interface PageRenderPatch

Overrides:

patchRender in class JQueryRenderPatch

Parameters:

reqInfo - the request information

result - the result returned by PageRenderPatch.beforeRender(org.zkoss.zk.ui.sys.RequestInfo), and the rendering result of a page will be written to it.

out - the real output sent to the client. It is the writer to write the patched result to.

Throws:

java.io.IOException
