Detailed Description

[AI] Concrete presenter for sound playback and control within the LEGO Island engine.

[AI] MxSoundPresenter manages the lifecycle and registration of sound resources and presentations, providing integration between an audio stream (via MxAudioPresenter base) and the MxSoundManager. It ensures that sound presenters are properly registered/unregistered and initialized/destroyed, reflecting correct resource handling for sound as a form of media presentation.

Constructor & Destructor Documentation

◆ ~MxSoundPresenter()

MxSoundPresenter::~MxSoundPresenter ( )
inlineoverride

[AI] Destructor, ensures resource release and deregisters the presenter from MxSoundManager.

[AI] Calls Destroy(TRUE) to trigger resource cleanup, including custom teardown logic.

Definition at line 22 of file mxsoundpresenter.h.

Member Function Documentation

◆ AddToManager()

MxResult MxSoundPresenter::AddToManager ( )
overridevirtual

[AI] Registers this presenter with the global MxSoundManager.

[AI] Called when the object needs to participate in system sound management. Returns SUCCESS if registration was performed, FAILURE otherwise (e.g., no sound manager).

Returns
MxResult Operation result code (SUCCESS/FAILURE). [AI]

Reimplemented from MxPresenter.

Reimplemented in MxWavePresenter.

Definition at line 26 of file mxsoundpresenter.cpp.

◆ ClassName()

const char * MxSoundPresenter::ClassName ( ) const
inlineoverridevirtual

[AI] Returns the class name of this instance.

[AI] Supports runtime type identification, consistent with MxMediaPresenter framework.

Returns
const char* Name of the class ("MxSoundPresenter"). [AI]

Reimplemented from MxAudioPresenter.

Reimplemented in MxWavePresenter.

Definition at line 47 of file mxsoundpresenter.h.

◆ Destroy() [1/2]

void MxSoundPresenter::Destroy ( )
inlineoverridevirtual

[AI] Public destroy method called by the engine to clean up the presenter.

[AI] Delegates to the protected Destroy(FALSE), ensuring proper resource management when called explicitly rather than by destructor. Informs the sound manager of its removal.

Reimplemented from MxMediaPresenter.

Reimplemented in MxWavePresenter.

Definition at line 29 of file mxsoundpresenter.h.

◆ Destroy() [2/2]

void MxSoundPresenter::Destroy ( MxBool  p_fromDestructor)
protected

[AI] Handles actual teardown logic for the presenter, including deregistration from manager.

[AI] If called from the destructor, ensures that the presenter is removed from the sound manager, and re-initializes the base presenter state. If not called from the destructor, explicitly invokes media base class destroy, which clears/frees all associated resources.

Parameters
p_fromDestructorFlag indicating destroy reason (TRUE if called from destructor). [AI]

Definition at line 10 of file mxsoundpresenter.cpp.

◆ HandlerClassName()

static const char * MxSoundPresenter::HandlerClassName ( )
inlinestatic

[AI] Returns the class name of the presenter as a static string.

[AI] Used for dynamic runtime type identification and factory pattern dispatch in the engine.

Returns
const char* Name of the handler class type. [AI]

Definition at line 36 of file mxsoundpresenter.h.

◆ IsA()

MxBool MxSoundPresenter::IsA ( const char *  p_name) const
inlineoverridevirtual

[AI] Tests if this instance is a MxSoundPresenter or derived type.

[AI] Performs a type check, supporting the polymorphic "IsA" idiom for object hierarchies. Delegates up to MxAudioPresenter if no match.

Parameters
p_nameName of the class to test. [AI]
Returns
MxBool True if this matches the requested type or any parent type. [AI]

Reimplemented from MxAudioPresenter.

Reimplemented in MxWavePresenter.
