Constructor Detail

### 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
