Constructor Detail

SineServer

public SineServer()

Create the SineServer, a composite periodic oscillator. Set default parameters for the amplitude (50) and the midline offset (50) and a default timebase of (.3 seconds). The time offset (peak shift) is 0.0 and the frequency multiplier is 1.0

Method Detail

calculateValue

public double calculateValue(double time)

This will calculate the value for a specific time.

getFreqFactor

public float getFreqFactor()

Returns the frequency multiplier of the SineServer.

Returns:

the frequency multiplier

See Also:

Writing VIB Data Sources: Get/Set Methods, setFreqFactor(float)

getMaxAmp

public int getMaxAmp()

Accesses the current maximum amplitude value.

Returns:

the maximum amplitude setting

See Also:

setMaxAmp(int), Writing VIB Data Sources: Get/Set Methods

getOffset

public int getOffset()

Returns the amplitude offset of the server.

Returns:

the amplitude offset setting.

See Also:

Writing VIB Data Sources: Get/Set Methods, setOffset(int)

getTimeOffset

public float getTimeOffset()

Returns the time offset of the SineServer (in seconds).

Returns:

the time offset value.

See Also:

Writing VIB Data Sources: Get/Set Methods, setTimeOffset(float)

refreshCurrentValue

public void refreshCurrentValue()

Sets the new value. This server uses the formula:

    newValue =  ( sin(x*f)*cos(x*f/5))*maxAmp + offSet;
 

where x is the time since the server started, in seconds, + the (optional) time offset, and f is the frequency multiplier (default is 1.0). This method is called automatically by the timer in SimpleDataSource every timebase interval.

Overrides:

refreshCurrentValue in class SimpleDataSource

setFreqFactor

public void setFreqFactor(float newValue)

Sets the frequency multiplier of the SineServer.

Parameters:

newValue - The new frequency multiplier value.

See Also:

Writing VIB Data Sources: Get/Set Methods, getTimeOffset()

setMaxAmp

public void setMaxAmp(int newValue)

Sets the amplitude of the server.

Parameters:

newValue - The new amplitude setting.

See Also:

Writing VIB Data Sources: Get/Set Methods, getMaxAmp()

setOffset

public void setOffset(int newValue)

Sets the amplitude offset of the server.

Parameters:

newValue - The new offset value.

See Also:

Writing VIB Data Sources: Get/Set Methods, getOffset()

setTimeOffset

public void setTimeOffset(float newValue)

Sets the time offset of the SineServer (in seconds).

Parameters:

newValue - The new time offset value.
