Examples of org.apache.fop.datatypes.PercentBaseContext

org.apache.fop.datatypes.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.
