Class DatatypeRuleToken

java.lang.Object

org.eclipse.xtext.parser.impl.DatatypeRuleToken

Direct Known Subclasses:

AntlrDatatypeRuleToken

public abstract class DatatypeRuleToken
extends Object

Return value of data type rules.

DatatypeRuleTokens can be merged with other DatatypeRuleTokens. We insert spaces on merge, if the merged token did not follow immediately, so we don't mess some corner cases up, e.g.:

• Dots returns EString: '.' '.' | '..';
• Vector returns EString: INT INT;
• NumbersOrReal returns EString: INT '.' INT | REAL;
• REAL: "('0'..'9')+'.'('0'..'9')+";
