Examples of CSVTokenizer

com.bbn.openmap.util.CSVTokenizer
Tokenizer for comma separated values files, at least as generated by excel.
token() returns the next token, which can be either:
- null, indicating an empty field.
- a Double, indicating a numeric field.
- a String, indicating an alphanumeric field.
- the NEWLINE object, indicating the end of a record.
- the EOF object, test with isEOF(), indicating the end of file.
```
 
```

The CSVTokenizer specifies the behaviour how to parse each line into a List of Strings.
org.jfree.report.util.CSVTokenizer
The csv tokenizer class allows an application to break a Comma Separated Value format into tokens. The tokenization method is much simpler than the one used by the StringTokenizer class. The CSVTokenizer methods do not distinguish among identifiers, numbers, and quoted strings, nor do they recognize and skip comments.
The set of separator (the characters that separate tokens) may be specified either at creation time or on a per-token basis.
An instance of CSVTokenizer behaves in one of two ways, depending on whether it was created with the returnSeparators flag having the value true or false:
- If the flag is false, delimiter characters serve to separate tokens. A token is a maximal sequence of consecutive characters that are not separator.
- If the flag is true, delimiter characters are themselves considered to be tokens. A token is thus either one delimiter character, or a maximal sequence of consecutive characters that are not separator.
A CSVTokenizer object internally maintains a current position within the string to be tokenized. Some operations advance this current position past the characters processed.
A token is returned by taking a substring of the string that was used to create the CSVTokenizer object.
The following is one example of the use of the tokenizer. The code:
```
 CSVTokenizer csvt = new CSVTokenizer("this,is,a,test"); while (csvt.hasMoreTokens()) { println(csvt.nextToken()); } 
```
prints the following output:
```
 this is a test 
```

"Thus saith the Lord GOD; When I shall have gathered the house of Israel from the people among whom they are scattered, and shall be sanctified in them in the sight of the heathen, then shall they dwell in their land that I have given to my servant Jacob." (Ezekiel 28:25) ========== Simple utility for using csv data files. For some purposes simple and flat file with comma separated value rows is more convinient way to write and read the data than corresponding xml or json structure. @author jukka.rahkonen@iki.fi
