public class DefinitionLexer
The DefinitionLexer
is an implementation of the
Lexer
interface for lexing a property definition.
Specifically, it is used for retrieving the pieces that make up a
property definition, the name, assignment symbol, and the
value.
For parsing purposes, if you wish to skip the assignment operator,
call setSkipSymbols(true)
.

public DefinitionLexer()
DefinitionLexer
with a starting
position of 0. Clients must call setTextBuffer()
to
initialize the text buffer used for the Lexer. To start lexing
from an offset other than 0, call setPosition()
.
