    public interface PercentBaseContext

This interface is used by the layout managers to provide relevant information back to the property percentage resolution logic, that is the percentages based property getValue() functions expect an object implementing this interface as an argument.

### Method Summary

All Methods Instance Methods Abstract Methods
`int` `getBaseLength(int lengthBase, FObj fobj)` Returns the base length for the given length base.

### Method Detail

#### getBaseLength

    int getBaseLength(int lengthBase,
                      FObj fobj)

Returns the base length for the given length base. Length base should be one of the constants defined in `LengthBase`.

Parameters:
  `lengthBase` - Indicates which type of the base length value is to be returned
  `fobj` - The FO object against which the percentage should be evaluated
Returns:
  The base length value of the given kind
