Class AssertionsPlugin

java.lang.Object
  org.ceryle.wiki.plugin.assertion.AssertionsPlugin

All Implemented Interfaces:

WikiPlugin, PluginConstants

Direct Known Subclasses:

Assertions

public class AssertionsPlugin
extends Object
implements WikiPlugin, PluginConstants

A query plugin that uses various methods from the AssertionHandler to list the entire set of wiki Assertions, or applies one or more filters upon that set. This operates without use of the WikiMapManager (i.e., pre-harvest).

NOTE: This plugin has been replaced by the AssertedPlugin.

The output can either mimic the original Assertions or be formatted as a bullet or numbered list, count only, etc.

Parameters

• page = 'pagename'. An optional parameter, filtering on page name when present.
• subject = 'name'. An optional parameter, filtering on subject when present.
• predicate = 'name'. An optional parameter, filtering on predicate when present.
• object = 'name'. An optional parameter, filtering on object when present.
• output = 'value'. An optional parameter. One of 'none', 'count', 'list', 'bullet', 'number', 'space', 'comma', or 'table'. The result is a list of wiki page names; this alters the output presentation (a description of each can be found at PluginTextUtils). In the absence of a parameter value the output will resemble a list of the original assertions.

If following any parameters an assertion expression is included, it will override the subject, predicate and object parameters (i.e., all three are ignored). The wild card "[*]" will match any page. E.g., "[*] [*] [*]" will match all pages — the same as providing no parameters or expression. "[*] [IsA] [Book]" will match all pages asserted as being a Book.

Example

The first example lists all Assertions, the second applies the specific filter, returning all wiki pages that have been asserted as instances of the class "Book".

    [{Assertions}]
    [{Assertions predicate='IsA' object='[Book]' }]
