UnknownUnit (udunits 5.5.0 API)

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

All Implemented Interfaces:

Serializable, Base, DerivableUnit, DerivedUnit, Unit
```
@Immutable
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(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(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 DerivedUnitImpl
    
    Parameters:
    
    object - The object.
    
    Returns:
    
    true if and only if this instance is semantically identical to the object.
  - hashCode
```
public int hashCode()
```
    Returns the hash code of this instance.
    
    Overrides:
    
    hashCode in class DerivedUnitImpl
    
    Returns:
    
    The hash code of this instance.
  - isDimensionless
```
public boolean isDimensionless()
```
    Indicates if this unit is dimensionless. An unknown unit is never dimensionless.
    
    Specified by:
    
    isDimensionless in interface Base
    
    Specified by:
    
    isDimensionless in interface Unit
    
    Overrides:
    
    isDimensionless in class BaseUnit
    
    Returns:
    
    false always.
