org.stekikun.dolmen.tagged.Optimiser.IdentInfo

Enclosing class:

Optimiser

public static final class Optimiser.IdentInfo
extends Object

Structure which represents how an indentifier in a regular expression is realized in optimised tagged regular expressions, i.e. provides tag addresses for the start and end of the expression bound to the identifier, and whether it is optional or not.

When the identifier is statically known to bind a single character only, the end tag address is omitted.
