Examples of org.apache.jetspeed.profiler.ProfileLocator

org.apache.jetspeed.profiler.ProfileLocator
Profile Locators are used to locate profiled portal resources such as pages, documents, and fragments. A locator contains properties describing the actually resource to be located. Since the locator is based on properties that are usually related to a user or other subject's profile, it is referred to as a profile locator.

Profiles can be created from a normalized Profile Locator Path The format of the path is name/value pairs of all property, separated by a path separator. An example locator path:
```
page:default.psml:artist:al-stewart:song:on-the-border
```
```
path:/sports/football/nfl/chiefs:language:en
```
