public class Divide
extends MasterCalculator

Calculates the division of two numbers. Specification This manipulator has a main value input and a divisor input. The result of the calulation is the division of the main value by the divisor value. The result is always a DoubleValueObject. Both inputs are required to produce an output. In other words, if only one input connector has changed (ever), no output value will be generated. An output is generated each time either the main input or the subtraction input is received. The output data quality will be the worse of the two input's quality. Properties will be combined in the output value object. The inputs' Color values are ignored. If a String input does not convert to a number, a Runtime Exception is thrown and a message is logged, and the last value is sent out with quality BAD.
Note: If you want a non-fractional output, you can use a Round manipulator on the output.

Constructor Detail

Divide

public Divide()

Constructor. This sets the Master Calculator operation to DIVIDE.

Method Detail

divisorValueInput

public void divisorValueInput(ValueChangedEvent newEvent)
                       throws VIBUpdateFailedException

This is the input method for the value that is the divisor. The ValueObject in the ValueChangedEvent is expected to be convertable to a non-zero number.

Parameters:

newEvent - an event from the registered data source

Throws:

VIBUpdateFailedException

See Also:

MasterCalculator.update(), MasterCalculator.valueInput(ValueChangedEvent)

getStaticLocationFor

public int getStaticLocationFor(java.lang.String loc)
                         throws BadParameterException

This is used by the StaticMethodEvent to determine which valueChanged method to call. An integer index is returned which is used by the valueChanged (int,ValueChangedEvent) method.

Overrides:

getStaticLocationFor in class MasterCalculator

Throws:

BadParameterException

toString

public java.lang.String toString()

Provides the description and status of the server as a String.

Overrides:

toString in class Manipulator

Returns:

a string description of this server

valueChanged

public void valueChanged(int loc,
                         ValueChangedEvent e)
                  throws VIBUpdateFailedException,
                         BadParameterException

This calls the proper valueChanged method based on the return from the getStaticLocationFor method.

Overrides:

valueChanged in class MasterCalculator

Throws:

VIBUpdateFailedException

BadParameterException
