Constructor & Destructor Documentation

Decompress16BitLEAudio()

Burger::Decompress16BitLEAudio::Decompress16BitLEAudio

(

)

Default constructor.

---

Initializes the defaults

Member Function Documentation

get_StaticRTTI()

const Burger::StaticRTTI * Burger::Decompress16BitLEAudio::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::Decompress.

New()

Burger::Decompress16BitLEAudio *BURGER_API Burger::Decompress16BitLEAudio::New ( void )

static

Allocate and initialize a Decompress16BitLEAudio.

---

Returns

A pointer to a default Decompress16BitLEAudio class or NULL if out of memory

See also

Delete(const T *)

Process()

Burger::eError Burger::Decompress16BitLEAudio::Process ( void * pOutput, uintptr_t uOutputChunkLength, const void * pInput, uintptr_t uInputChunkLength )

overridevirtual

Decompress audio data using little endian 16 bit words.

---

Input data is assumed to be little endian 16 bit words. There is no decompression being performed.

Parameters

pOutput	Pointer to the buffer to accept the decompressed data
uOutputChunkLength	Number of bytes in the output buffer
pInput	Pointer to data to decompress
uInputChunkLength	Number of bytes in the data to decompress

Returns

Decompress::eError code with zero if no failure, non-zero is an error code

Implements Burger::Decompress.

Reset()

Burger::eError Burger::Decompress16BitLEAudio::Reset ( void )

overridevirtual

Resets the decompresser to defaults.

---

Returns

kErrorNone if successful

Implements Burger::Decompress.
