add_children_props

Description:

public void add_children_props (Element element, string[]? wanted_categories, string[]? blacklist, string[]? whitelist)

Adds all the properties of a Element that match the criteria as children properties of the track element.

If the name of element's ElementFactory is not in blacklist, and the factory's ELEMENT_METADATA_KLASS contains at least one member of wanted_categories (e.g. DECODER), then all the properties of element that are also in whitelist are added as child properties of this using add_child_property.

This is intended to be used by subclasses when constructing.

Parameters:

this	A TrackElement
element	The child object to retrieve properties from
wanted_categories	An array of element factory "klass" categories to whitelist, or null to accept all categories
blacklist	A blacklist of element factory names, or null to not blacklist any element factory
whitelist	A whitelist of element property names, or null to whitelist all writeable properties
