Anixe.Ion library is a .NET library that provides reader with fast, non-cached, forward only access to *.ion files and writer to build ion file content.

Anixe.Ion library provides static factory which can create an instance for IonReader interface. Factory enables two ways of creation the IonReader instance:

1. With path to the file. File is opened with: FileMode.Open, FileAccess.Read, FileShare.ReadWrite. Possible argument exceptions:
   • ArgumentException with message "File path must be defined!" when given file path is null, empty or contains only white spaces.
   • ArgumentException with message "File 'XXX' does not exist!" when given XXX path does not exist on disk.
2. With Stream.

• CurrentLine gets current line value. It causes new string allocation from CurrentRawLine
• CurrentRawLine gets current line value as ArraySegment. It is allocation free. Data is from rented buffer.
• CurrentLineNumber gets current line number
• CurrentSection gets information about current section name. Its value will change only when CurrentLine is on line which begins with '['
• IsSectionHeader gets boolean value indicating whether first character of CurrentLine is '['
• IsComment gets boolean value indicating whether first character of CurrentLine is '#'
• IsTableRow gets boolean value indicating whether first character of CurrentLine is '|'
• IsTableHeaderRow gets boolean value indicating whether first character of CurrentLine is '|' and current table header was not already passed
• IsTableHeaderSeparatorRow gets boolean value indicating whether first character of CurrentLine is '|' and second character is '-'
• IsTableDataRow gets boolean value indicating whether first character of CurrentLine is '|' and current table header was already passed
• IsEmptyLine returns boolean value indicating whether first character of CurrentLine is empty string or line is filled with empty spaces
• IsProperty returns boolean value indicating whether other properties are false

• Read reads each *.ion file line and returns boolean value indicating whether reading was successful or not
• Dispose calls Dispose method of the underlying stream

• OnReadSection the event handler fired for each section with section name in args

• Read the main method of the class, it reads the stream provided by IonReader and fires an event for each section
