Class AbstractConversion

java.lang.Object

util.PropertyContainer

stella.sensor.AbstractConversion

All Implemented Interfaces:

Serializable, Cloneable, ConvertToPhysical, PropertySupplying

Direct Known Subclasses:

AbstractDerivative, AnalogRainConversion, DewPointConvert, IdenticalConversion

public abstract class AbstractConversion
extends PropertyContainer
implements ConvertToPhysical, Serializable

The class to dynamically construct ConvertToPhysical instances using a properties object as a constructor. May also be used as a base class for ConvertToPhysical and PhysicalDerivative instances. To allow the definition of the diverse decimal format retrieval methods in both interfaces, the ConvertToPhysical and the PhysicalDerivative interface, all relevant keys and default definitions are present already in this class definition.

To allow the conversion to be transported with the event object, this class also implements the Serializable interface. To keep the serialized version slender, the keys and defaults used are defined transient and are used only during the construction phase to spark the existance of private copies of the required instances.

Note that due to the necessary serialization of conversion classes during data event generation, it is not feasible to implement a conversion class as an inner class.

Method Detail

getUnit

public String getUnit()

Returns the unit of the physical meaningful quantity. Required in ConvertToPhysical.

Specified by:

getUnit in interface ConvertToPhysical

getValueFormat

public NumberFormat getValueFormat()

Returns the decimal format of the value. Required in ConvertToPhysical.

Specified by:

getValueFormat in interface ConvertToPhysical

getSigmaValueFormat

public NumberFormat getSigmaValueFormat()

Returns the decimal format of the sigma of the value. Required in ConvertToPhysical.

Specified by:

getSigmaValueFormat in interface ConvertToPhysical

createConversion

public static final ConvertToPhysical createConversion(Map prop)

Constructs a new scheduling instance using the mapping of the PropertySupplying.KEY_CLASS to the class name to derive the class to instantiate. If this property is defined, a new Scheduling instance with the stated class name is created, the supplied properties used as an argument in the constructor. Can throw a lot of exceptions if unsuccessful.
