Class CSVTokenizer

java.lang.Object
  net.sf.csv4j.CSVTokenizer

All Implemented Interfaces:

java.lang.Iterable<java.lang.String>, java.util.Enumeration<java.lang.String>, java.util.Iterator<java.lang.String>, Tokenizer<java.lang.String>

public class CSVTokenizer
extends java.lang.Object
implements Tokenizer<java.lang.String>, java.util.Enumeration<java.lang.String>, java.util.Iterator<java.lang.String>, java.lang.Iterable<java.lang.String>

Provides an API similar to StringTokenizer. In addition to StringTokenizer's two interfaces, this class also supports the Iterator interface. It supports too many style of iterations as a result:

• Tokenizer style
• Iterator style
• Enumerator style

1.0

Constructor Detail

CSVTokenizer

public CSVTokenizer(java.lang.String line)
             throws ParseException

Creates a tokenizer from the specified CSV line.

Parameters:

line - string to tokenize

Throws:

ParseException - if the line cannot be tokenized

Method Detail

nextToken

public java.lang.String nextToken()

Returns the next token.

Specified by:

nextToken in interface Tokenizer<java.lang.String>

Returns:

next token string

hasMoreTokens

public boolean hasMoreTokens()

Indicates if more tokens are available.

Specified by:

hasMoreTokens in interface Tokenizer<java.lang.String>

Returns:

true if more tokens; false if not

countTokens

public int countTokens()

Indicates how many tokens are left. Note the value returned is not constant; calls to Tokenizer.nextToken() will cause the count to reduce.

Specified by:

countTokens in interface Tokenizer<java.lang.String>

Returns:

number of tokens left

hasMoreElements

public boolean hasMoreElements()

Specified by:

hasMoreElements in interface java.util.Enumeration<java.lang.String>

nextElement

public java.lang.String nextElement()

Specified by:

nextElement in interface java.util.Enumeration<java.lang.String>

hasNext

public boolean hasNext()

Specified by:

hasNext in interface java.util.Iterator<java.lang.String>

next

public java.lang.String next()

Specified by:

next in interface java.util.Iterator<java.lang.String>

remove

public void remove()

Not supported.

Specified by:

remove in interface java.util.Iterator<java.lang.String>

Throws:

java.lang.RuntimeException - always thrown

reset

public void reset()

Reset the iterator back to the beginning.

iterator

public java.util.Iterator<java.lang.String> iterator()

Specified by:

iterator in interface java.lang.Iterable<java.lang.String>
