stronginherited |
Used to specifiy how the corresponding channels are to be resolved between two connected Node's, based on either a Node's input (the default), it's output, or specified by user.
Enumerator | |
---|---|
SPECIFIED |
Number of channels has been specified by user or is non-settable. |
MATCHES_INPUT |
This Node matches it's channels with it's input. |
MATCHES_OUTPUT |
This Node matches it's channels with it's output. |

void cinder::audio::GenOscNode::setWaveform | ( | WaveformType | waveformType | ) |
Sets the WaveformType of the internal wavetable. This can be a heavy operation and requires thread synchronization, so be careful not to block the audio thread for too long.
void cinder::audio::GenOscNode::setWaveTable | ( | const WaveTable2dRef & | waveTable | ) |
Assigns waveTable as the internal wavetable. This allows one to share a WaveTable2d across multiple Node's.
const WaveTable2dRef cinder::audio::GenOscNode::getWaveTable | ( | ) | const |
Returns a reference to the current wavetable.
WaveformType cinder::audio::GenOscNode::getWaveForm | ( | ) | const |
Returns the current WaveformType.
size_t cinder::audio::GenOscNode::getTableSize | ( | ) | const |
Returns the size of the owned WaveTable2d.

Returns the channel mode.
|
inherited |
Returns the maximum number of channels any input has.

inherited |
Returns true if there is an unmanageable cycle betweeen sourceNode and destNode. If any Node's in the traversal returns true for supportsCycles(), this method will return false.
|
inherited |
Returns an immutable reference to the inputs container.
|
inherited |
Returns a copy of the NodeRef's referenced by the this Node as outputs. The copy is necessary because outputs are stored internally with weak_ptr's.

protectedinherited |
Returns a pair of frame indices for Nodes that wish to support sample accurate enable and disable.
The first index is where processing should start, the second is where it should end. Should only be called on the audio thread from within a Node's process() method. Unless scheduled (with Context::schedule()), this will be [0, getFramesPerBlock()]
