VolumeShaper.Configuration.Builder
extends Object
Builder class for a VolumeShaper.Configuration object.
Here is an example where Builder is used to define the
VolumeShaper.Configuration.
VolumeShaper.Configuration LINEAR_RAMP =
new VolumeShaper.Configuration.Builder()
.setInterpolatorType(VolumeShaper.Configuration.INTERPOLATOR_TYPE_LINEAR)
.setCurve(new float[] { 0.f, 1.f }, // times
new float[] { 0.f, 1.f }) // volumes
.setDuration(1000)
.build();

Public constructors
Builder
public Builder ()
Constructs a new Builder with the defaults.
public Builder (VolumeShaper.Configuration configuration)
Constructs a new Builder with settings
copied from a given VolumeShaper.Configuration.
| Parameters |
|---|
configuration |
VolumeShaper.Configuration: prototypical configuration
which will be reused in the new Builder.
This value cannot be null. |
Public methods
scaleToEndVolume
public VolumeShaper.Configuration.Builder scaleToEndVolume (float volume)
Scale the curve end volume to a target value.
Keeps the start volume the same.
This works best if the volume curve is monotonic.
| Parameters |
|---|
volume |
float: the target end volume to use. |
scaleToStartVolume
public VolumeShaper.Configuration.Builder scaleToStartVolume (float volume)
Scale the curve start volume to a target value.
Keeps the end volume the same.
This works best if the volume curve is monotonic.
| Parameters |
|---|
volume |
float: the target start volume to use. |
setCurve
public VolumeShaper.Configuration.Builder setCurve (float[] times,
float[] volumes)
Sets the volume curve.
The volume curve is represented by a set of control points given by
two float arrays of equal length,
one representing the time (x) coordinates
and one corresponding to the volume (y) coordinates.
The length must be at least 2
and no greater than VolumeShaper.Configuration#getMaximumCurvePoints().
The volume curve is normalized as follows:
time (x) coordinates should be monotonically increasing, from 0.f to 1.f;
volume (y) coordinates must be within 0.f to 1.f.
The time scale is set by setDuration(long).
| Parameters |
|---|
times |
float: an array of float values representing
the time line of the volume curve.
This value cannot be null. |
volumes |
float: an array of float values representing
the amplitude of the volume curve.
This value cannot be null. |
setDuration
public VolumeShaper.Configuration.Builder setDuration (long durationMillis)
Sets the VolumeShaper duration in milliseconds.
If omitted, the default duration is 1 second.
