Proxies

Methods of the shock_proxy namespace may be implemented in a class or interface for overriding language behavior, known as proxies.

shock_proxy::call()

A static shock_proxy::call() method may be defined with any number of parameters and any result type, overriding the behavior of calling the class object.

shock_proxy static function call():T {}

A multi-method may be used, allowing for multiple call signatures.

shock_proxy::get()

Note: Overriding the property accessor with a possibly String or QName key type (including base types * and Object) will override all names (like .x), except when calling a method (like .m()). In that case, a class is said to be dynamic.

If the user needs to access an instance variable in such a case it is recommended to use a fixed expression as in

<?fixed={object.q::n}?>

shock_proxy function get(key:K):V {
    //
}

shock_proxy::set()

Note: Overriding the property accessor with a possibly String or QName key type (including base types * and Object) will override all names (like .x), except when calling a method (like .m()). In that case, a class is said to be dynamic.

shock_proxy function set(key:K, value:V):void {
    //
}

shock_proxy::delete()

Note: Overriding the property accessor with a possibly String or QName key type (including base types * and Object) will override all names (like .x), except when calling a method (like .m()). In that case, a class is said to be dynamic.

shock_proxy function delete(key:K):Boolean {
    //
}

shock_proxy::has()

Overrides the behavior of the in operator.

shock_proxy function has(key:K):Boolean {
    //
}

shock_proxy::getAttribute()

Overrides the behavior of the .@k accessor.

shock_proxy function getAttribute(key:K):V {
    //
}

shock_proxy::setAttribute()

Overrides the behavior of the .@k = v accessor.

shock_proxy function setAttribute(key:K, value:V):void {
    //
}

shock_proxy::deleteAttribute()

Overrides the behavior of the delete (...).@k accessor.

shock_proxy function deleteAttribute(key:K):Boolean {
    //
}

shock_proxy::filter()

Overrides the behavior of the filter operator (.(test)).

shock_proxy function filter(testFn:function(T):Boolean):E {
    //
}

shock_proxy::descendants()

Overrides the behavior of the descendants operator (..x). The parameter is expected to be typed String or QName.

shock_proxy function descendants(name:QName):E {
    //
}
