FilterProperties FilterProperties::FilterProperties(void); Undocumented function.

addChorus void FilterProperties::add_chorus(float drymix, float wet1, float wet2, float wet3, float delay, float rate, float depth, float feedback); Description: Add a chorus filter to the end of the DSP chain.

addCompress void FilterProperties::add_compress(float threshold, float attack, float release, float gainmakeup); Description: Add a compress filter to the end of the DSP chain.

addDistort void FilterProperties::add_distort(float level); Description: Add a distort filter to the end of the DSP chain.

addEcho void FilterProperties::add_echo(float drymix, float wetmix, float delay, float decayratio); Description: Add a echo filter to the end of the DSP chain.

addFlange void FilterProperties::add_flange(float drymix, float wetmix, float depth, float rate); Description: Add a flange filter to the end of the DSP chain.

addHighpass void FilterProperties::add_highpass(float cutoff_freq, float resonance_q); Description: Add a highpass filter to the end of the DSP chain.

addLowpass void FilterProperties::add_lowpass(float cutoff_freq, float resonance_q); Description: Add a lowpass filter to the end of the DSP chain.

addNormalize void FilterProperties::add_normalize(float fadetime, float threshold, float maxamp); Description: Add a normalize filter to the end of the DSP chain.

addParameq void FilterProperties::add_parameq(float center_freq, float bandwidth, float gain); Description: Add a parameq filter to the end of the DSP chain.

addPitchshift void FilterProperties::add_pitchshift(float pitch, float fftsize, float overlap); Description: Add a pitchshift filter to the end of the DSP chain.

addReverb void FilterProperties::add_reverb(float drymix, float wetmix, float roomsize, float damp, float width); Description: Add a reverb filter to the end of the DSP chain.

getClassType static TypeHandle FilterProperties::get_class_type(void); Undocumented function.

getClassType static TypeHandle TypedReferenceCount::get_class_type(void); Undocumented function.

getClassType static TypeHandle TypedObject::get_class_type(void); Undocumented function.

getType virtual TypeHandle TypedObject::get_type(void) const = 0; Derived classes should override this function to return get_class_type().

getTypeIndex int TypedObject::get_type_index(void) const; Description: Returns the internal index number associated with this object's TypeHandle, a unique number for each different type. This is equivalent to get_type().get_index().

isExactType bool TypedObject::is_exact_type(TypeHandle handle) const; Description: Returns true if the current object is the indicated type exactly.

isOfType bool TypedObject::is_of_type(TypeHandle handle) const; Description: Returns true if the current object is or derives from the indicated type.

getClassType static TypeHandle ReferenceCount::get_class_type(void); Undocumented function.

getRefCount int ReferenceCount::get_ref_count(void) const; Description: Returns the current reference count.

ref void ReferenceCount::ref(void) const; Description: Explicitly increments the reference count. User code should avoid using ref() and unref() directly, which can result in missed reference counts. Instead, let a PointerTo object manage the reference counting automatically. This function is const, even though it changes the object, because generally fiddling with an object's reference count isn't considered part of fiddling with the object. An object might be const in other ways, but we still need to accurately count the number of references to it.

testRefCountIntegrity bool ReferenceCount::test_ref_count_integrity(void) const; Description: Does some easy checks to make sure that the reference count isn't completely bogus. Returns true if ok, false otherwise.

testRefCountNonzero bool ReferenceCount::test_ref_count_nonzero(void) const; Description: Does some easy checks to make sure that the reference count isn't zero, or completely bogus. Returns true if ok, false otherwise.

unref bool ReferenceCount::unref(void) const; Description: Explicitly decrements the reference count. Note that the object will not be implicitly deleted by unref() simply because the reference count drops to zero. (Having a member function delete itself is problematic; plus, we don't have a virtual destructor anyway.) However, see the helper function unref_delete(). User code should avoid using ref() and unref() directly, which can result in missed reference counts. Instead, let a PointerTo object manage the reference counting automatically. This function is const, even though it changes the object, because generally fiddling with an object's reference count isn't considered part of fiddling with the object. An object might be const in other ways, but we still need to accurately count the number of references to it. The return value is true if the new reference count is nonzero, false if it is zero.
