# MovieAudio

from pandac.PandaModules import MovieAudio

Class : MovieAudio
Description : A MovieAudio is actually any source that provides a sequence of audio samples. That could include an AVI file, a microphone, or an internet TV station.
The difference between a MovieAudio and a MovieAudioCursor is like the difference between a filename and a file handle. The MovieAudio just indicates a particular movie. The MovieAudioCursor is what allows access.

MovieAudio MovieAudio::MovieAudio(string const &name = ("Blank Audio")); Description: This constructor returns a null audio stream --- a stream of total silence, at 8000 samples per second. To get more interesting audio, you need to construct a subclass of this class.

get static PointerTo< MovieAudio > MovieAudio::get(Filename const &name); Description: Obtains a MovieAudio that references a file.

getClassType static TypeHandle MovieAudio::get_class_type(void); Undocumented function.

getFilename Filename const &MovieAudio::get_filename(void) const; Filename: movieAudio.I Created by: jyelon (02Jul07) PANDA 3D SOFTWARE Copyright (c) Carnegie Mellon University. All rights reserved. All use of this software is subject to the terms of the revised BSD license. You should have received a copy of this license along with this source code in a file named "LICENSE." Description: Returns the movie's filename. A movie is not guaranteed to have a filename, if not, then this function returns a null filename.

open virtual PointerTo< MovieAudioCursor > MovieAudio::open(void); Description: Open this audio, returning a MovieAudioCursor

getClassType static TypeHandle TypedWritableReferenceCount::get_class_type(void); Undocumented function.

getClassType static TypeHandle TypedWritable::get_class_type(void); Undocumented function.

getClassType static TypeHandle TypedObject::get_class_type(void); Undocumented function.

getType virtual TypeHandle TypedObject::get_type(void) const = 0; Derived classes should override this function to return get_class_type().

getTypeIndex int TypedObject::get_type_index(void) const; Description: Returns the internal index number associated with this object's TypeHandle, a unique number for each different type. This is equivalent to get_type().get_index().

isExactType bool TypedObject::is_exact_type(TypeHandle handle) const; Description: Returns true if the current object is the indicated type exactly.

isOfType bool TypedObject::is_of_type(TypeHandle handle) const; Description: Returns true if the current object is or derives from the indicated type.

getClassType static TypeHandle ReferenceCount::get_class_type(void); Undocumented function.

getRefCount int ReferenceCount::get_ref_count(void) const; Description: Returns the current reference count.

ref void ReferenceCount::ref(void) const; Description: Explicitly increments the reference count. User code should avoid using ref() and unref() directly, which can result in missed reference counts. Instead, let a PointerTo object manage the reference counting automatically. This function is const, even though it changes the object, because generally fiddling with an object's reference count isn't considered part of fiddling with the object. An object might be const in other ways, but we still need to accurately count the number of references to it.

testRefCountIntegrity bool ReferenceCount::test_ref_count_integrity(void) const; Description: Does some easy checks to make sure that the reference count isn't completely bogus. Returns true if ok, false otherwise.

testRefCountNonzero bool ReferenceCount::test_ref_count_nonzero(void) const; Description: Does some easy checks to make sure that the reference count isn't zero, or completely bogus. Returns true if ok, false otherwise.

unref bool ReferenceCount::unref(void) const; Description: Explicitly decrements the reference count. Note that the object will not be implicitly deleted by unref() simply because the reference count drops to zero. (Having a member function delete itself is problematic; plus, we don't have a virtual destructor anyway.) However, see the helper function unref_delete(). User code should avoid using ref() and unref() directly, which can result in missed reference counts. Instead, let a PointerTo object manage the reference counting automatically. This function is const, even though it changes the object, because generally fiddling with an object's reference count isn't considered part of fiddling with the object. An object might be const in other ways, but we still need to accurately count the number of references to it. The return value is true if the new reference count is nonzero, false if it is zero.

Namable Namable::Namable(string const &initial_name = ("")); Description:

clearName void Namable::clear_name(void); Description: Resets the Namable's name to empty.

getClassType static TypeHandle Namable::get_class_type(void); Undocumented function.

getName string const &Namable::get_name(void) const; Description:

hasName bool Namable::has_name(void) const; Description: Returns true if the Namable has a nonempty name set, false if the name is empty.

operator = Namable &Namable::operator =(Namable const &other); Description:

output void Namable::output(ostream &out) const; In the absence of any definition to the contrary, outputting a Namable will write out its name. Description: Outputs the Namable. This function simply writes the name to the output stream; most Namable derivatives will probably redefine this.

setName void Namable::set_name(string const &name); Description:
