All Implemented Interfaces:

IShallowParser

public class XtendShallowParser
extends ShallowParserBase<XtendShallowParser.EXtendShallowParserState>

Shallow parser for Xtend.

Same features as the Java shallow parser:

• The parser recognizes types (classes, enums, interfaces, annotations), methods and attributes, and individual statements.
• It recognizes the nesting of statements (e.g. in loops), but does not parse into the statements. For example, it recognizes an if-statement and provides the list of sub-statements, but does not provide direct access to the if-condition.
• Import and package statements are parsed as meta information.
• Annotations are recognized as meta information, but only annotations at types and methods. Annotations at parameters are not parsed, as the parser does not parse into the parameter list of methods.
• The parser does not recognize anonymous classes. These are treated as a single long statement or attribute. Inner classes, however, are parsed correctly.
• The parser recognizes try, switch and if assignments to fields.
• The parser can deal with multiple classes in a single file.

isFilteredToken

protected boolean isFilteredToken(IToken token,
                                  IToken previousToken)

Template method that can be used to ignore/filter certain tokens. Default implementation ignores comments.

Overrides:

isFilteredToken in class ShallowParserBase<XtendShallowParser.EXtendShallowParserState>

previousToken - the last non-filtered token (can be used for context sensitive filtering). This may be null is no previous token exists.
