Class: HTMLPurifier_URIFilter - X-Ref
Chainable filters for custom URI processing.
These filters can perform custom actions on a URI filter object,
including transformation or blacklisting. A filter named Foo
must have a corresponding configuration directive %URI.Foo,
unless always_load is specified to be true.
The following contexts may be available while URIFilters are being
processed:
- EmbeddedURI: true if URI is an embedded resource that will
be loaded automatically on page load
- CurrentToken: a reference to the token that is currently
being processed
- CurrentAttr: the name of the attribute that is currently being
processed
- CurrentCSSProperty: the name of the CSS property that is
currently being processed (if applicable)
prepare($config)

Performs initialization for the filter. If the filter returns
false, this means that it shouldn't be considered active.
