Detailed description

_assign

Signature: void _assign (const QAudioBuffer other)

Description: Assigns another object to self

_create

Signature: void _create

Description: Ensures the C++ object is created

Use this method to ensure the C++ object is created, for example to ensure that resources are allocated. Usually C++ objects are created on demand and not necessarily when the script object is created.

_destroy

Signature: void _destroy

Description: Explicitly destroys the object

Explicitly destroys the object on C++ side if it was owned by the script interpreter. Subsequent access to this object will throw an exception. If the object is not owned by the script, this method will do nothing.

_destroyed?

Signature: [const] bool _destroyed?

Description: Returns a value indicating whether the object was already destroyed

This method returns true, if the object was destroyed, either explicitly or by the C++ side. The latter may happen, if the object is owned by a C++ object which got destroyed itself.

_is_const_object?

Signature: [const] bool _is_const_object?

Description: Returns a value indicating whether the reference is a const reference

This method returns true, if self is a const reference. In that case, only const methods may be called on self.

_manage

Signature: void _manage

Description: Marks the object as managed by the script side.

After calling this method on an object, the script side will be responsible for the management of the object. This method may be called if an object is returned from a C++ function and the object is known not to be owned by any C++ instance. If necessary, the script side may delete the object if the script's reference is no longer required.

Usually it's not required to call this method. It has been introduced in version 0.24.

_unmanage

Signature: void _unmanage

Description: Marks the object as no longer owned by the script side.

Calling this method will make this object no longer owned by the script's memory management. Instead, the object must be managed in some other way. Usually this method may be called if it is known that some C++ object holds and manages this object. Technically speaking, this method will turn the script's reference into a weak reference. After the script engine decides to delete the reference, the object itself will still exist. If the object is not managed otherwise, memory leaks will occur.

Usually it's not required to call this method. It has been introduced in version 0.24.

assign

Signature: QAudioBuffer assign (const QAudioBuffer other)

Description: Method QAudioBuffer &QAudioBuffer::operator=(const QAudioBuffer &other)

byteCount

Signature: [const] int byteCount

Description: Method int QAudioBuffer::byteCount()

constData

Signature: [const] void * constData

Description: Method const void *QAudioBuffer::constData()

create

Signature: void create

Description: Ensures the C++ object is created

Use of this method is deprecated. Use _create instead

Use this method to ensure the C++ object is created, for example to ensure that resources are allocated. Usually C++ objects are created on demand and not necessarily when the script object is created.

data

(1) Signature: [const] void * data

Description: Method const void *QAudioBuffer::data()

(2) Signature: void * data

Description: Method void *QAudioBuffer::data()

destroy

Signature: void destroy

Description: Explicitly destroys the object

Use of this method is deprecated. Use _destroy instead

Explicitly destroys the object on C++ side if it was owned by the script interpreter. Subsequent access to this object will throw an exception. If the object is not owned by the script, this method will do nothing.

destroyed?

Signature: [const] bool destroyed?

Description: Returns a value indicating whether the object was already destroyed

Use of this method is deprecated. Use _destroyed? instead

This method returns true, if the object was destroyed, either explicitly or by the C++ side. The latter may happen, if the object is owned by a C++ object which got destroyed itself.

dup

Signature: [const] new QAudioBuffer ptr dup

Description: Creates a copy of self

Python specific notes:
This method also implements '__copy__' and '__deepcopy__'.

duration

Signature: [const] long long duration

Description: Method qint64 QAudioBuffer::duration()

format

Signature: [const] QAudioFormat format

Description: Method QAudioFormat QAudioBuffer::format()

frameCount

Signature: [const] int frameCount

Description: Method int QAudioBuffer::frameCount()

isValid?

Signature: [const] bool isValid?

Description: Method bool QAudioBuffer::isValid()

is_const_object?

Signature: [const] bool is_const_object?

Description: Returns a value indicating whether the reference is a const reference

Use of this method is deprecated. Use _is_const_object? instead

This method returns true, if self is a const reference. In that case, only const methods may be called on self.

new

(1) Signature: [static] new QAudioBuffer new

Description: Constructor QAudioBuffer::QAudioBuffer()

This method creates an object of class QAudioBuffer.

Python specific notes:
This method is the default initializer of the object.

(2) Signature: [static] new QAudioBuffer new (const QAudioBuffer other)

Description: Constructor QAudioBuffer::QAudioBuffer(const QAudioBuffer &other)

This method creates an object of class QAudioBuffer.

Python specific notes:
This method is the default initializer of the object.

(3) Signature: [static] new QAudioBuffer new (bytes data, const QAudioFormat format, long long startTime = -1)

Description: Constructor QAudioBuffer::QAudioBuffer(const QByteArray &data, const QAudioFormat &format, qint64 startTime)

This method creates an object of class QAudioBuffer.

Python specific notes:
This method is the default initializer of the object.

(4) Signature: [static] new QAudioBuffer new (int numFrames, const QAudioFormat format, long long startTime = -1)

Description: Constructor QAudioBuffer::QAudioBuffer(int numFrames, const QAudioFormat &format, qint64 startTime)

This method creates an object of class QAudioBuffer.

Python specific notes:
This method is the default initializer of the object.

sampleCount

Signature: [const] int sampleCount

Description: Method int QAudioBuffer::sampleCount()

startTime

Signature: [const] long long startTime

Description: Method qint64 QAudioBuffer::startTime()
