Abstract Class HTMLPurifier_URIFilter
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)
|$always_load||True if this filter should always be loaded.||HTMLPurifier_URIFilter|
|$name||Unique identifier of filter.||HTMLPurifier_URIFilter|
|$post||True if this filter should be run after scheme validation.||HTMLPurifier_URIFilter|
|filter()||Filter a URI object||HTMLPurifier_URIFilter|
|prepare()||Performs initialization for the filter. If the filter returns false, this means that it shouldn't be considered active.||HTMLPurifier_URIFilter|
This permits a filter to be named Foo without the corresponding %URI.Foo directive existing.
