This is the full implementation of the AudioBuffer object. There are two ways to create these objects from an audio context and this patch implements only one of them. The construction of the AudioBuffer object is a two step process: the object should be created with operator new first, and then InitializeBuffers should be called on it. InitializeBuffers is fallible, because it uses the JS API to create the underlying typed arrays, but that's fine, since the length of the buffers comes from web content, and we don't want to use infallible allocations for those anyways. We hold on to the JS objects from the C++ implementation, and trace through all of those objects, so that a GC does not kill those object without us knowing. The buffer should be possible to manipulate from both C++ and JS, and the C++ object probably needs to support a set of methods for the C++ callers at some point.

# 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. If not
|
|
# specified, defaults to "mozilla::dom::InterfaceName" for
|
|
# non-worker non-external-or-callback interfaces, to
|
|
# "mozilla::dom::workers::InterfaceName" for worker
|
|
# non-external interfaces, to 'nsIDOM' followed by the
|
|
# interface name for non-worker external-or-callback
|
|
# interfaces, and to "JSObject" for worker external-or-callback
|
|
# interfaces.
|
|
# * 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 bindings should be disabled if the
|
|
# global pref for Web IDL bindings is set to false. This is a
|
|
# risk mitigation strategy and it will cause all of the Web IDL
|
|
# bindings marked as prefable to fall back to the xpconnect
|
|
# bindings in case something goes wrong. This defaults to False.
|
|
# Setting this on objects which only have Web IDL bindings does
|
|
# not make any sense.
|
|
# 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
