Constructor Detail

TotalMemory

public TotalMemory(java.lang.String vitalKey,
                   VitalSignProperties properties)

Creates the vital sign. This method must pass-through to the super-class so the vital sign can be auto-loaded.

Method Detail

getCurrentMeasurement

protected AbstractVitalMeasurement getCurrentMeasurement()

Takes a measurement of the vital sign at the current moment and returns it to the caller. This method should be implemented by subclasses that are automatically called by the vitals manager on a periodic basis. The default implementation in this superclass is to return null, leaving the implementation to a subclass.

Overrides:

getCurrentMeasurement in class VitalSign

Returns:

the current measurement for this vital sign or null if no implementation

basicGetMaximumMeasurement

public AbstractVitalMeasurement basicGetMaximumMeasurement()

Returns the maximum theoritical value of the vital sign.

Overrides:

basicGetMaximumMeasurement in class VitalSign

Returns:

the current measurement for this vital sign or null if no implementation
