# DOM Bindings Configuration.
#
# The WebIDL interfaces are defined in dom/webidl. For each such interface, there
# is a corresponding entry in the configuration table below. The configuration
# table maps each interface name to a |descriptor| or list of |descriptor|s.
#
# Valid fields for all descriptors:
#   * nativeType - The native type (concrete class or XPCOM interface) that
#                  instances of this interface will unwrap to (required).
#   * headerFile - The file in which the nativeType is declared (defaults
#                  to an educated guess).
#   * castable - Indicates whether the value in the wrapper can be cast to
#                nativeType, or whether it needs to be QI-ed (defaults to True
#                for everything but callback interfaces and external interfaces,
#                for which it defaults to false and is not allowed to be set
#                at all).
#   * concrete - Indicates whether there exist objects with this interface as
#                their primary interface (defaults to True).
#   * prefable - Indicates whether this binding is subject to the about:config
#                pref, or whether it's always enabled (defaults to False).
#                Cannot be set on external interfaces.
#   * workers - Indicates whether the descriptor is intended to be used for
#               worker threads (defaults to false).
#   * customTrace - The native class will use a custom trace hook (defaults to
#                   true for workers, false otherwise).
#   * customFinalize - The native class will use a custom finalize hook
#                      (defaults to true for workers, false otherwise).
#   * notflattened - The native type does not have nsIClassInfo, so when
#                    wrapping it the right IID needs to be passed in.
#   * register - True if this binding should be registered.  Defaults to true.
#   * binaryNames - Dict for mapping method and attribute names to different
#                   names when calling the native methods (defaults to an empty
#                   dict). The keys are the property names as they appear in the
#                   .webidl file and the values are the names as they should be
#                   in the WebIDL.
#   * wrapperCache: True if this object is a wrapper cache.  Objects that are
#                   not can only be returned from a limited set of methods,
#                   cannot be prefable, and must ensure that they disallow
#                   XPConnect wrapping.  Always true for worker descriptors.
#                   Defaults to true.
#
#   The following fields are either a string, an array (defaults to an empty
#   array) or a dictionary with three possible keys (all, getterOnly and
#   setterOnly) each having such an array as the value
#
#   * implicitJSContext - attributes and methods specified in the .webidl file
#                         that require a JSContext as the first argument
#   * resultNotAddRefed - attributes and methods specified in the .webidl file
#                         that do not AddRef the return value
