Class UnknownUnit

java.lang.Object
  ucar.units.UnitImpl
      ucar.units.DerivedUnitImpl
          ucar.units.BaseUnit
              ucar.units.UnknownUnit

All Implemented Interfaces:

java.io.Serializable, Base, DerivableUnit, DerivedUnit, Unit

public final class UnknownUnit
extends BaseUnit

Provides support for unknown base units. This can be used, for example, to accomodate an unknown unit (e.g. "foo"). Values in such a unit will only be convertible with units derived from "foo" (e.g. "20 foo").

Method Detail

create

public static UnknownUnit create(java.lang.String name)
                          throws NameException

Factory method for constructing an unknown unit from a name.

Parameters:

name - The name of the unit.

Returns:

The unknown unit.

Throws:

NameException - name == null.

equals

public boolean equals(java.lang.Object object)

Indicates if this unit is semantically identical to an object.

Specified by:

equals in interface Base

Specified by:

equals in interface Unit

Overrides:

equals in class BaseUnit

Parameters:

object - The object.

Returns:
