Member Function Documentation

classData()

virtual const ZFClass * ZFAudio::classData ( void )

inlinevirtual

get instance's class info

Reimplemented from ZFStyle.

E_AudioOnLoad()

zfidentity ZFAudio::E_AudioOnLoad ( void )

static

see ZFObject::observerNotify

called when audio load finished, ensured called in ZFThread::mainThread
param0 is a ZFResultType shows the load result, param1 is a v_zfstring shows the error hint if load fail

E_AudioOnStart()

zfidentity ZFAudio::E_AudioOnStart ( void )

static

see ZFObject::observerNotify

called when audio started, ensured called in ZFThread::mainThread

E_AudioOnStop()

zfidentity ZFAudio::E_AudioOnStop ( void )

static

see ZFObject::observerNotify

called when audio stopped, ensured called in ZFThread::mainThread
param0 is a ZFResultType shows the play result, param1 is a v_zfstring shows the error hint if play fail

E_AudioOnResume()

zfidentity ZFAudio::E_AudioOnResume ( void )

static

see ZFObject::observerNotify

called when audio start success and about to play, or resume from pause, ensured called in ZFThread::mainThread

E_AudioOnPause()

zfidentity ZFAudio::E_AudioOnPause ( void )

static

see ZFObject::observerNotify

called when audio pause, ensured called in ZFThread::mainThread

E_AudioOnLoop()

zfidentity ZFAudio::E_AudioOnLoop ( void )

static

see ZFObject::observerNotify

called when audio looped, ensured called in ZFThread::mainThread

start()

virtual void ZFAudio::start ( )

virtual

start to play

it's ensured safe to call start immediately after load, but E_AudioOnLoad may called after E_AudioOnStart for this case
once loaded, it's ensured able to start and stop more than one time

stop()

virtual void ZFAudio::stop ( )

virtual

stop play

Implements ZFTaskId.

loopCur()

virtual zfindex ZFAudio::loopCur ( )

virtual

current loop count

reset when start, but keep previous value when stop

position()

virtual void ZFAudio::position ( zftimet position )

virtual

change current position

note, change position may or may not work, depends on impl

objectOnInit()

virtual void ZFAudio::objectOnInit ( void )

protectedvirtual

override this to init your object

subclass must call superclass's objectOnInit before any other code if override
you may also declare objectOnInit with params like this:

zfclass Parent : ... {
    ...
protected:
    virtual void objectOnInit(void) {...};
};
zfclass Child : Parent {
protected:
    // override all parent's objectOnInit is also required,
    // because of function hiding of C++
    zfoverride
    virtual void objectOnInit(void) {
        zfsuper::objectOnInit();
    }
    // custom init entry
    virtual void objectOnInit(Params...) {
        // your extra init steps
        ...
    }
};

Warning

objectOnInit and objectOnDealloc is called as a virtual function, take good care of other virtual function call, use zfself::func() instead of this->func() if necessary, or use objectOnInitFinish/objectOnDeallocPrepare, or declare your own constructor with ZFOBJECT_DECLARE_WITH_CUSTOM_CTOR

Note

(ZFTAG_LIMITATION) due to limitations of C++, if your parent type declared objectOnInit with different params, and your child type want to override part of those objectOnInit, then your child type must also override all objectOnInit that parent declared, otherwise, some may be hidden

for objects that designed not to be allocated by user, you should use ZFOBJECT_PRIVATE_ALLOC, typically usage:

zfclass MyObject : zfextend ZFObject {
    ZFOBJECT_DECLARE(MyObject, ZFObject)
    ZFOBJECT_PRIVATE_ALLOC("should be created by MyObject::instanceForXxx only")
 
public:
    static zfauto instanceForXxx(xxx) {
        // can only be allocated by reflection
        return zfself::ClassData()->newInstance();
    }
};
static void func(void) {
    // MyObject *obj = zfobjAlloc(MyObject); // would compile error
    zfauto obj = MyObject::instanceForXxx(xxx); // OK
}

Reimplemented from ZFObject.

objectOnDealloc()

virtual void ZFAudio::objectOnDealloc ( void )

protectedvirtual

override this to destroy your object

subclass must call superclass's objectOnDealloc after any other code if override
see objectOnInit for more info

Reimplemented from ZFObject.

objectInfoImpl()

virtual void ZFAudio::objectInfoImpl ( zfstring & ret )

protectedvirtual

see objectInfo

Reimplemented from ZFObject.

serializableOnSerializeFromData()

virtual zfbool ZFAudio::serializableOnSerializeFromData ( const ZFSerializableData & serializableData, zfstring * outErrorHint = zft_zfnull, ZFSerializableData * outErrorPos = zft_zfnull )

protectedvirtual

for serializable data that has "category" attribute, ZFSerializable would ignore it and leave it to subclass to resolve, see ZFSerializable

while overriding this method, you should call super first, and then check whether super has resolved the data
if subclass should resolve the category, you should mark data as resolved and return whether resolve success
if not, subclass should leave the data unresoved and return true

Reimplemented from ZFSerializable.

serializableOnSerializeToData()

virtual zfbool ZFAudio::serializableOnSerializeToData ( ZFSerializableData & serializableData, zfstring * outErrorHint = zft_zfnull, ZFSerializable * refOwner = zft_zfnull )

protectedvirtual

corresponding to serializableOnSerializeFromData, return whether the task is success, see ZFSerializable

Reimplemented from ZFSerializable.
