/**
|
|
* 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)
|
|
*
|
|
* @warning This filter is called before scheme object validation occurs.
|
|
* Make sure, if you require a specific scheme object, you
|
|
* you check that it exists. This allows filters to convert
|
|
* proprietary URI schemes into regular ones.
