Class TimeStamp

java.lang.Object

net.beadsproject.beads.core.TimeStamp

public class TimeStamp
extends java.lang.Object

TimeStamps store time with respect to the current AudioContext. Specifically, the TimeStamp stores a time step and an index into a buffer.

Constructor Detail

TimeStamp

public TimeStamp(AudioContext context,
                 long timeStep,
                 int index)

Instantiates a new TimeStamp with the given time step, context and buffer index. Use AudioContext.generateTimeStamp(int) to generate a TimeStamp for the current time.

Parameters:

context - the AudioContext.

timeStep - the time step.

index - the index.

TimeStamp

public TimeStamp(AudioContext context,
                 long timeInSamples)

Instantiates a new TimeStamp with the given time step, context and buffer index. Use AudioContext.generateTimeStamp(int) to generate a TimeStamp for the current time.

Parameters:

context - the AudioContext.

timeStep - the time step.

index - the index.

Method Detail

getTimeMS

public double getTimeMS()

Gets the time of the TimeStamp in milliseconds.

Returns:

the time in milliseconds.

getTimeSamples

public long getTimeSamples()

Gets the time in samples.

Returns:

the time in samples.

since

public double since(TimeStamp oldest)

isBefore

public boolean isBefore(TimeStamp other)

isAfter

public boolean isAfter(TimeStamp other)

subtract

public static TimeStamp subtract(AudioContext ac,
                                 TimeStamp a,
                                 TimeStamp b)

add

public static TimeStamp add(AudioContext ac,
                            TimeStamp a,
                            TimeStamp b)
