Class Ini

  • All Implemented Interfaces:
    Map<String,​Ini.Section>
    public class Ini
extends Object
implements Map<String,​Ini.Section>
    A class representing the INI text configuration format.

    An Ini instance is a map of Sections, keyed by section name. Each Section is itself a map of String name/value pairs. Name/value pairs are guaranteed to be unique within each Section only - not across the entire Ini instance.

    Since:
    1.0

      • merge

        public void merge​(Map<String,​Ini.Section> m)
        Merges the contents of m's Ini.Section objects into self. This differs from putAll(Map), in that each section is merged with the existing one. For example the following two ini blocks are merged and the result is the third

        Initial: 

         [section1]
 key1 = value1

 [section2]
 key2 = value2
        To be merged: 
         [section1]
 foo = bar

 [section2]
 key2 = new value
        Result: 
         [section1]
 key1 = value1
 foo = bar

 [section2]
 key2 = new value

        Parameters:
        m - map to be merged
