    - #### PercentLength

          public PercentLength(double factor,
                       PercentBase lbase)

      Main constructor. Construct an object based on a factor (the percent, as a factor) and an object which has a method to return the Length which provides the "base" for the actual length that is modeled.
      Parameters:
        `factor` - the percentage factor, expressed as a decimal (e.g. use .95 to represent 95%)
        `lbase` - base property to which the factor should be applied

  - ### Method Detail

    - #### getBaseLength

          public PercentBase getBaseLength()

      Returns:
        the base

    - #### getPercentage

          protected double getPercentage()

      Used during property resolution to check for negative percentages
      Returns:
        the percentage value

    - #### isAbsolute

          public boolean isAbsolute()

      Return false because percent-length are always relative. 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.

    - #### 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.

    - #### getString

          public java.lang.String getString()

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

    - #### getValue

          public int getValue()

      Return the length of this PercentLength. 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

    - #### toString

          public java.lang.String toString()

      Description copied from class: `Property`
      Overrides:
        `toString` in class `Property`
      Returns:
        the String equivalent of this

    - #### hashCode

          public int hashCode()

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

    - #### equals

          public boolean equals(java.lang.Object obj)

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