    - #### getInstance

          public static EnumNumber getInstance(Property enumProperty)

      Returns the canonical EnumNumber instance corresponding to the given Property
      Parameters:
        `enumProperty` - the base EnumProperty
      Returns:
        the canonical instance

    - #### getEnum

          public int getEnum()

      This method expects to be overridden by subclasses
      Specified by:
        `getEnum` in interface `Numeric`
      Overrides:
        `getEnum` in class `Property`
      Returns:
        integer equivalent of enumerated property value

    - #### getString

          public java.lang.String getString()

      This method expects to be overridden by subclasses.
      Overrides:
        `getString` in class `Property`
      Returns:
        String property value

    - #### getObject

          public java.lang.Object getObject()

      This method expects to be overridden by subclasses
      Overrides:
        `getObject` in class `Property`
      Returns:
        Object property value

    - #### equals

          public boolean equals(java.lang.Object obj)

      Overrides:
        `equals` in class `java.lang.Object`

    - #### hashCode

          public int hashCode()

      Overrides:
        `hashCode` in class `java.lang.Object`

    - #### getDimension

          public int getDimension()

      Return the dimension of this numeric. Plain numbers has a dimension of 0 and length has a dimension of 1. Other dimension can occur as a result of multiplications and divisions.
      Specified by:
        `getDimension` in interface `Numeric`
      Returns:
        the dimension.

    - #### isAbsolute

          public boolean isAbsolute()

      Return true if the numeric is an absolute value. Relative values are percentages and table-column-units. All other numerics are absolute. Always `true` for instances of this type
      Specified by:
        `isAbsolute` in interface `Numeric`
      Returns:
        true when the numeric is absolute.

    - #### getNumericValue

          public double getNumericValue(PercentBaseContext context)

      Return the value of this Numeric logs an error, because it's not supposed to be called
      Specified by:
        `getNumericValue` in interface `Numeric`
      Parameters:
        `context` - The context for the length calculation (for percentage based lengths)
      Returns:
        the computed value.

    - #### getValue

          public int getValue(PercentBaseContext context)

      Returns the value of this numeric as an int. logs an error, because it's not supposed to be called
      Specified by:
        `getValue` in interface `Numeric`
      Parameters:
        `context` - the context for the length calculation (for percentage based lengths)
      Returns:
        the value as an integer.

    - #### getValue

          public int getValue()

      Returns the value of this numeric as an int. logs an error, because it's not supposed to be called
      Specified by:
        `getValue` in interface `Numeric`
      Returns:
        the value as an integer.

          public double getNumericValue()

      Return the value of this Numeric logs an error, because it's not supposed to be called
      Specified by:
        `getNumericValue` in interface `Numeric`
      Returns:
        the computed value.
