Examples of org.eclipse.jface.text.Document

org.eclipse.jface.text.Document
Default document implementation. Uses a {@link org.eclipse.jface.text.GapTextStore} wrappedinside a {@link org.eclipse.jface.text.CopyOnWriteTextStore} as text store.
The used line tracker considers the following strings as line delimiters: "\n", "\r", "\r\n". In case of a text replacement across line delimiter boundaries and with different line delimiters, the line tracker might have to be repaired. Use {@link #isLineInformationRepairNeeded(int,int,String)} before doing the text replace if youhave the need to discover such a situation.

The document is ready to use. It has a default position category for which a default position updater is installed.

Performance: The implementation should perform reasonably well for typical source code documents. It is not designed for very large documents of a size of several megabytes. Space-saving implementations are initially used for both the text store and the line tracker; the first modification after a {@link #set(String) set} incurs the cost to transform thedocument structures to efficiently handle updates.

See {@link GapTextStore} and TreeLineTracker for algorithmic behavior of the useddocument structures.
