  - ### Method Detail

    - #### getInstance

          public static FixedLength getInstance(double numUnits,
                                                String units,
                                                float sourceResolution)

      Return the cached `FixedLength` instance corresponding to the computed value in base-units (millipoints).
      Parameters:
        `numUnits` - quantity of input units
        `units` - input unit specifier
        `sourceResolution` - input/source resolution (= ratio of pixels per pt)
      Returns:
        the canonical FixedLength instance corresponding to the given number of units and unit specifier in the given resolution

    - #### getInstance

          public static FixedLength getInstance(double numUnits,
                                                String units)

      Return the cached `FixedLength` instance corresponding to the computed value This method assumes a source-resolution of 1 (1px = 1pt)
      Parameters:
        `numUnits` - input units
        `units` - unit specifier
      Returns:
        the canonical FixedLength instance corresponding to the given number of units and unit specifier

    - #### getInstance

          public static FixedLength getInstance(double numUnits)

      Return the cached `FixedLength` instance corresponding to the computed value. This method assumes 'millipoints' (non-standard) as units, and an implied source-resolution of 1 (1px = 1pt).
      Parameters:
        `numUnits` - input units
      Returns:
        the canonical FixedLength instance corresponding to the given number of units and unit specifier

    - #### getValue

          public int getValue()

      Returns the length in 1/1000ths of a point (millipoints)
      Returns:
        the length in millipoints

    - #### getValue

          public int getValue(PercentBaseContext context)

      Returns the length in 1/1000ths of a point (millipoints)
      Parameters:
        `context` - The context for the length calculation (for percentage based lengths)
      Returns:
        the length in millipoints

    - #### getNumericValue

          public double getNumericValue()

      Return the value of this Numeric
      Returns:
        the computed value.

    - #### getNumericValue

          public double getNumericValue(PercentBaseContext context)

      Return the value of this Numeric
      Parameters:
        `context` - The context for the length calculation (for percentage based lengths)
      Returns:
        the computed value.

    - #### isAbsolute

          public boolean isAbsolute()

      Return true since a FixedLength is always absolute. Return true if the numeric is an absolute value. Relative values are percentages and table-column-units. All other numerics are absolute.
      Returns:
        true when the numeric is absolute.

    - #### toString

          public String toString()

      Overrides:
        `toString` in class `Property`

    - #### equals

          public boolean equals(Object obj)

      Overrides:
        `equals` in class `Object`

    - #### hashCode

          public int hashCode()

      Overrides:
        `hashCode` in class `Object`
