Class TokenScanner

  • public class TokenScanner
extends java.lang.Object
    Returns non-whitespace, non-comment tokens from an RSyntaxDocument, one at a time. This can be used by simplistic LanguageSupports to "parse" for simple, easily-identifiable tokens, such as curly braces and TokenTypes.VARIABLEs. For example, to identify code blocks for languages structured like C and Java, you can use this class in conjunction with CodeBlock and VariableDeclaration to create an easily-parsable model of your source code.
