Detailed Description

The inidom class implements a minimal INI DOM parser.

It parses a file or string of INI-formatted data and produces a dom tree representing the data. It creates "s" elements for each section, "k" elements for each key, "p" elements for each pound-delimited comment, and "c" elements for each semicolon-delimited comments. It adds a "v" attribute to each element, containing the value. For each "k" element, it also adds a "k" attribute, containing the name of the key. Text dom nodes (nodes of type TEXT_DOMNODETYPE) are used to preserve whitespace.

For example, the following INI:

[section 1] #pound comment ;semicolon comment key1=value1 key2=value2

[section 2] key 1=value 1 key 2=value 2 #pound comment ;semicolon comment

would produce the following dom tree:

<k k="key1" v="value1"> <k k="key2" v="value2">

<k k="key 1" v="value 1"> <k k="key 2" v="value 2">

(Note the blank line of text between the sections. This is the text domnode, used to preserve the whitespace.)

Constructor & Destructor Documentation

inidom() [1/2]

inidom::inidom

(

)

Creates a new instance of the inidom class.

inidom() [2/2]

inidom::inidom

(

bool

stringcacheenabled

)

Creates a new instance of the inidom class, allowing the user to enable or disable the "string cache" for this instance.

By default, as each domnode is added to the inidom tree, tag and attribute names and values are stored in a string cache and pointers into the cache are assigned to each node. Reference counters are kept and the string is removed from the cache when no more nodes are using it. If the data is highly repetitive this conserves memory at the cost of speed.

If the string cache is disabled then memory is allocated in each domnode for names and values and freed when the domnode is freed. This is faster but uses much more memory.

~inidom()

virtual inidom::~inidom ( )

virtual

Deletes this instance of the inidom class.
