Class TLexerEntry

java.lang.Object

org.stekikun.dolmen.tagged.TLexerEntry

public final class TLexerEntry
extends Object

A tagged lexer entry is the encoded optimised version of a syntactic lexer entry. It contains a single tagged regular expression gathering all the different clauses of the original entry, and describes semantic actions in terms of how bound names are implemented into tags.
