Method Details

execute

public String execute(Context context,
 Map<String,String> params)
               throws PluginException

This is the main entry point for any plugin. The parameters are parsed, and a special parameter called "_body" signifies the name of the plugin body, i.e. the part of the plugin that is not a parameter of the form "key=value". This has been separated using an empty line.

Note that it is preferred that the plugin returns XHTML-compliant HTML (i.e. close all tags, use <br /> instead of <br>, etc.

Specified by:

execute in interface Plugin

Parameters:

context - The current WikiContext.

params - A Map which contains key-value pairs. Any parameter that the user has specified on the wiki page will contain String-String parameters, but it is possible that at some future date, JSPWiki will give you other things that are not Strings.

Returns:

HTML, ready to be included into the rendered page.

Throws:

PluginException - In case anything goes wrong.
