SIDerivedDimensionRepresentativeConcept

public class DerivedDimensionRepresentativeConcept
extends DimensionRepresentativeConcept

A representative concept in the unitSystem ontology for a set of units for a specific physical dimension that is derived from other dimensions. For example, the Force dimension is derived from:
Force = Mass * Position / (Time ^ 2)

And its SI unit Newtons (N) is derived from:
N = kg * m / (s ^ 2)

Dimensions can be composed of other derived dimensions hierarchically. For example, the force dimension can also be derived as:
Velocity = Position / Time
Acceleration = Velocity / Time
Force = Mass * Acceleration

Constructor Detail

DerivedDimensionRepresentativeConcept

public DerivedDimensionRepresentativeConcept(CompositeEntity ontology,
                                             java.lang.String name)
                                      throws NameDuplicationException,
                                             IllegalActionException

Create a new DerivedUnitRepresentativeConcept with the specified name and ontology.

Parameters:

ontology - The specified ontology where this concept resides.

name - The specified name for the concept.

Throws:

NameDuplicationException - If the ontology already contains a concept with the specified name.

IllegalActionException - If the base class throws it.

Method Detail

getComponentBaseDimensions

public java.util.Map<BaseDimensionRepresentativeConcept,java.lang.Integer> getComponentBaseDimensions()
                                                                                                     throws IllegalActionException

Return the component base dimensions map for this derived unit dimension.

Returns:

The map of component base dimensions and their exponents for this derived dimension.

Throws:

IllegalActionException - Thrown if there is a problem getting the component base dimensions map.

getComponentDimensions

public java.util.Map<DimensionRepresentativeConcept,java.lang.Integer> getComponentDimensions()
                                                                                             throws IllegalActionException

Returns:

The map of component dimensions and their exponents for this derived dimension.

Throws:

IllegalActionException - Thrown if there is a problem getting the component dimensions map.

_createInfiniteConceptInstance in class DimensionRepresentativeConcept

Parameters:

infiniteConceptString - The string that represents the unit concept to be returned.

Returns:

The BaseUnitConcept represented by the given string.
