Member Function Documentation

get_StaticRTTI()

const Burger::StaticRTTI * Burger::SoundManager::Buffer::get_StaticRTTI ( void ) const

overridevirtualnoexcept

Get the description to the class.

---

This virtual function will pull the pointer to the StaticRTTI instance that has the name of the class. Due to it being virtual, it will be the name of the most derived class.

Returns

Pointer to a global, read only instance of StaticRTTI for the true class

Reimplemented from Burger::Base.

Reimplemented in Burger::SoundBufferRez.

GetBufferDescription() [1/2]

BufferDecoder * Burger::SoundManager::Buffer::GetBufferDescription ( void )

inline

Returns the contained BufferDecoder_t state.

---

Accessor for the BufferDecoder_t

Returns

Pointer to the contained BufferDecoder_t

GetBufferDescription() [2/2]

const BufferDecoder * Burger::SoundManager::Buffer::GetBufferDescription ( void ) const

inline

Returns the contained BufferDecoder_t state.

---

Accessor for the BufferDecoder_t

Returns

Pointer to the contained BufferDecoder_t as const

GetDirectSoundBuffer8()

IDirectSoundBuffer8 * Burger::SoundManager::Buffer::GetDirectSoundBuffer8 ( void ) const

inline

Gets the buffer's DirectSoundBuffer8.

---

If a buffer was allocated, returns the pointer to the attached DirectSoundBuffer8

Note

This is only available on Windows

Returns

The attached DirectSoundBuffer8

GetPan()

uint_t Burger::SoundManager::Buffer::GetPan ( void ) const

inline

Gets the buffer's stereo pan setting.

---

Gets the default pan setting for the audio data.

Returns

The buffer's default pan setting

See also

SetPan(uint_t)

GetSampleRate()

uint_t Burger::SoundManager::Buffer::GetSampleRate ( void ) const

inline

Gets the buffer's sample rate.

---

Gets the default sample rate for the audio data.

Returns

The buffer's default sample rate

See also

SetSampleRate(uint_t)

GetVolume()

uint_t Burger::SoundManager::Buffer::GetVolume ( void ) const

inline

Gets the buffer's default volume setting.

---

Gets the default volume setting for the audio data.

Returns

The buffer's default volume setting

See also

SetVolume(uint_t)

Init() [1/2]

uint_t BURGER_API Burger::SoundManager::Buffer::Init

(

const BufferDescription_t *

pRawData

)

Attach sound data to buffer.

---

Pass a pointer to a structure that describes audio data in memory and set up this buffer to use this data.

Note

This function assumes the audio data is persistent

SampleRate, Pan and Volume are set to defaults in this function

Parameters

pRawData

Pointer to the description of the audio data

Returns

Zero if no error, non-zero on error

See also

Init(const void *,uintptr_t)

Init() [2/2]

uint_t BURGER_API Burger::SoundManager::Buffer::Init	(	const void *	pSoundFile,
		uintptr_t	uLength )

Attach sound data to buffer.

---

Pass a pointer to a sound file loaded into memory and this function will parse the file and determine how to play the file and sets up some defaults

SampleRate, Pan and Volume are set to defaults in this function

Note

This function assumes the audio data is persistent

Parameters

pSoundFile	Pointer to the sound file in memory
uLength	Length of the sound file in bytes

Returns

Zero if no error, non-zero on error

Parameters

pSoundManager

Pointer to the parent sound manager class

Returns

Zero if no error, non-zero on error
