public class QuotedStringTokenizer

extends java.util.StringTokenizer

Method Detail

hasMoreTokens

public boolean hasMoreTokens()

Description copied from class: java.util.StringTokenizer

Tells if there are more tokens.

---

nextToken

public java.lang.String nextToken()
                           throws java.util.NoSuchElementException

Description copied from class: java.util.StringTokenizer

Returns the nextToken of the string.

---

nextToken

public java.lang.String nextToken(java.lang.String delim)
                           throws java.util.NoSuchElementException

Description copied from class: java.util.StringTokenizer

Returns the nextToken, changing the delimiter set to the given delim. The change of the delimiter set is permanent, ie. the next call of nextToken(), uses the same delimiter set.

---

hasMoreElements

public boolean hasMoreElements()

Description copied from class: java.util.StringTokenizer

This does the same as hasMoreTokens. This is the Enumeration interface method.

---

nextElement

public java.lang.Object nextElement()
                             throws java.util.NoSuchElementException

Description copied from class: java.util.StringTokenizer

This does the same as nextTokens. This is the Enumeration interface method.

---

countTokens

public int countTokens()

Not implemented.

---

quote

public static java.lang.String quote(java.lang.String s,
                                     java.lang.String delim)

Quote a string. The string is quoted only if quoting is required due to embeded delimiters, quote characters or the empty string.

---

quote

public static void quote(java.lang.StringBuffer buf,
                         java.lang.String s)

Quote a string into a StringBuffer.

---

unquote

public static java.lang.String unquote(java.lang.String s)

Unquote a string.
