Class FieldCursor

java.lang.Object
  org.makumba.providers.datadefinition.makumba.FieldCursor

public class FieldCursor
extends Object

This is the field definition tokenizer. The lookup metods return false or null if the respective token has not been encountered. The expect methods throw a DataDefinitionParseError instead. Some lookup methods simply do lookupLetters for now, they can be refined later (e.g. letter followed by letters or digits, etc).
