Constructor Detail

JJackAudioEvent

public JJackAudioEvent(long timestamp,
                       java.lang.Object client,
                       java.nio.FloatBuffer[] inputBuffer,
                       java.nio.FloatBuffer[] outputBuffer)

Constructor. Creates a new JJackAudioEvent instance with the given parameters.

Parameters:

timestamp - UNIX timestamp of event occurrence

client - source client issuing the event

inputBuffer - array of input buffers to deliver with this event

outputBuffer - array of output buffers to deliver with this event

Method Detail

getTimestamp

public long getTimestamp()

Returns the UNIX timestamp marking the time of event occurrence.

Returns:

the UNIX timestamp value

getInput

public java.nio.FloatBuffer getInput()

Returns the mono input buffer.

Returns:

input buffer of the mono input port.

See Also:

getMonoInputPort()

setInput

public void setInput(java.nio.FloatBuffer buf)

Sets the mono input buffer.

Parameters:

buf - input buffer

See Also:

setMonoInputPort(int)

getOutput

public java.nio.FloatBuffer getOutput()

Returns the mono output buffer.

Returns:

output buffer of the mono output port.

See Also:

getMonoOutputPort()

setOutput

public void setOutput(java.nio.FloatBuffer buf)

Sets the mono output buffer.

Parameters:

buf - output buffer

See Also:

setMonoOutputPort(int)

getInput

public java.nio.FloatBuffer getInput(int chan)

Returns the input buffer of the specified channel.

Parameters:

chan - channel number

Returns:

input buffer

setInput

public void setInput(int chan,
                     java.nio.FloatBuffer buf)

Sets the input buffer of the specified channel.

Parameters:

chan - channel number

buf - input buffer

getOutput

public java.nio.FloatBuffer getOutput(int chan)

Returns the output buffer of the specified channel.

Parameters:

chan - channel number

Returns:

output buffer

setOutput

public void setOutput(int chan,
                      java.nio.FloatBuffer buf)

Sets the output buffer of the specified channel.

Parameters:

chan - channel number

buf - output buffer

countInputPorts

public int countInputPorts()

Returns the number of channels with an input port.

Returns:

number of channels with an input port

countOutputPorts

public int countOutputPorts()

Returns the number of channels with an output port.

Returns:

number of channels with an output port

countChannels

public int countChannels()

Returns the number of channels that have both an input and an output channel. Usually, the number of input and output channels are equal, in that case countInputPorts() == countOutputPorts() == countChannels(). If the number of input and output ports differ, the minimum of both determines the number of channels.

Returns:

number of channels

getInputs

public java.nio.FloatBuffer[] getInputs()

Returns all input buffers.

Returns:

array of all input buffers

getOutputs

public java.nio.FloatBuffer[] getOutputs()

Returns all output buffers.

Returns:

array of all output buffers

getMonoInputPort

public int getMonoInputPort()

Returns the index number of the input port used for mono access.

Returns:

input port index number

getMonoOutputPort

public int getMonoOutputPort()

Returns the index number of the output port used for mono access.

Returns:

output port index number

setMonoInputPort

public void setMonoInputPort(int port)

Sets the index number of the input port used for mono access.

setMonoOutputPort

public void setMonoOutputPort(int port)

Sets the index number of the output port used for mono access.

getChannels

public java.util.Collection getChannels()

Returns all channels. The number of elements in the Collection returned is equals to countChannels().

Returns:

Collection of JJackAudioChannel
