Static helper methods for working with text.

Public Methods

Method	Description
GetControlCharacterName ( char controlCharacter ) : string	Gets the name of the control character. For unknown characters, the unicode codepoint is returned as 4-digit hexadecimal value.
GetNextCaretPosition ( ITextSource textSource, int offset, LogicalDirection direction, CaretPositioningMode mode ) : int	Gets the next caret position. This method is NOT equivalent to the actual caret movement when using VisualLine.GetNextCaretPosition. In real caret movement, there are additional caret stops at line starts and ends. However, this method doesn't know anything about lines: it is often called with a textSource that represents only a single VisualTextElement.
GetSingleIndentationSegment ( ITextSource textSource, int offset, int indentationSize ) : ISegment	Gets a single indentation segment starting at offset - at most one tab or indentationSize spaces.

Private Methods

Method	Description
GetCharacterClass ( char c ) : CharacterClass
GetLeadingWhitespace ( DocumentLine documentLine ) : ISegment
GetLeadingWhitespace ( TextDocument document, DocumentLine documentLine ) : ISegment
GetTrailingWhitespace ( DocumentLine documentLine ) : ISegment
GetTrailingWhitespace ( TextDocument document, DocumentLine documentLine ) : ISegment
GetWhitespaceAfter ( ITextSource textSource, int offset ) : ISegment
GetWhitespaceBefore ( ITextSource textSource, int offset ) : ISegment
