Ini (Apache Shiro 1.4.1 API)

java.lang.Object
- org.apache.shiro.config.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

public void load(InputStream is)
          throws ConfigurationException
```
    Loads the INI-formatted text backed by the given InputStream into this instance. This implementation will close the input stream after it has finished loading. It is expected that the stream's contents are UTF-8 encoded.
    
    Parameters:
    
    is - the InputStream from which to read the INI-formatted text
    
    Throws:
    
    ConfigurationException - if unable

```
    Loads the INI-formatted text backed by the given Reader into this instance. This implementation will close the reader after it has finished loading.
    
    Parameters:
    
    reader - the Reader from which to read the INI-formatted text
  - 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
