|
|
* 'Directive' => new stdclass(),
|
|
* )
|
|
* )
|
|
*
|
|
* The stdclass may have the following properties:
|
|
*
|
|
* - If isAlias isn't set:
|
|
* - type: Integer type of directive, see HTMLPurifier_VarParser for definitions
|
|
* - allow_null: If set, this directive allows null values
|
|
* - aliases: If set, an associative array of value aliases to real values
|
|
* - allowed: If set, a lookup array of allowed (string) values
|
|
* - If isAlias is set:
|
|
* - namespace: Namespace this directive aliases to
|
|
* - name: Directive name this directive aliases to
|
|
*
|
|
* In certain degenerate cases, stdclass will actually be an integer. In
|
|
* that case, the value is equivalent to an stdclass with the type
|
|
* property set to the integer. If the integer is negative, type is
|
|
* equal to the absolute value of integer, and allow_null is true.
|
|
*
|
|
* This class is friendly with HTMLPurifier_Config. If you need introspection
|
|
* about the schema, you're better of using the ConfigSchema_Interchange,
|
|
* which uses more memory but has much richer information.
