 org.isqlviewer.util.StringTokenizer
| StringTokenizer | | public class StringTokenizer implements Enumeration<String>(Code) | | This class is primarily a copy Of the java.util.StringTokenizer with some extentsions.
Things you can do in this version and not in default JDK version.
- This class also supports tokenizing with quotes.
- Get the index within the original text that the token was at.

| Method Summary | |
| public int | countTokens()
Calculates the number of times that this tokenizer's nextToken method can be called before it
generates an exception. | | public int | getTokenIndex()
| | public boolean | hasMoreElements()
Returns the same value as the hasMoreTokens method. | | public boolean | hasMoreTokens()
Tests if there are more tokens available from this tokenizer's string. | | public boolean | isQuotesEnabled()
Determines if this tokenizer is sensitive to quoted strings. | | public String | nextElement()
Returns the same value as the nextToken method, except that its declared return value is
Object rather than String. | | public String | nextToken()
Returns the next token from this string tokenizer. | | public String | nextToken(String delim)
Returns the next token in this string tokenizer's string. | | public void | setQuotesEnabled(boolean quotesEnabled)
Sets quotes enabled for determining tokenzation. | | public String[] | toArray()
|
| StringTokenizer | | public StringTokenizer(String str, String delim, boolean returnDelims)(Code) | | Constructs a string tokenizer for the specified string. All characters in the delim argument are
the delimiters for separating tokens.
If the returnDelims flag is true, then the delimiter characters are also returned
as tokens. Each delimiter is returned as a string of length one. If the flag is false, the
delimiter characters are skipped and only serve as separators between tokens.
Note that if delim is null, this constructor does not throw an exception. However, trying
to invoke other methods on the resulting StringTokenizer may result in a NullPointerException.
Parameters:
str - a string to be parsed.
Parameters:
delim - the delimiters.
Parameters:
returnDelims - flag indicating whether to return the delimiters as tokens.
exception:
NullPointerException - if str is null |
| StringTokenizer | | public StringTokenizer(String str, String delim)(Code) | | Constructs a string tokenizer for the specified string. The characters in the delim argument are
the delimiters for separating tokens. Delimiter characters themselves will not be treated as tokens.
Note that if delim is null, this constructor does not throw an exception. However, trying
to invoke other methods on the resulting StringTokenizer may result in a NullPointerException.
Parameters:
str - a string to be parsed.
Parameters:
delim - the delimiters.
exception:
NullPointerException - if str is null |
| StringTokenizer | | public StringTokenizer(String str)(Code) | | Constructs a string tokenizer for the specified string. The tokenizer uses the default delimiter set, which is
" \t\n\r\f": the space character, the tab character, the newline character,
the carriage-return character, and the form-feed character. Delimiter characters themselves will not be treated
as tokens.
Parameters:
str - a string to be parsed.
exception:
NullPointerException - if str is null |
| countTokens | | public int countTokens()(Code) | | Calculates the number of times that this tokenizer's nextToken method can be called before it
generates an exception. The current position is not advanced.
the number of tokens remaining in the string using the current delimiter set.

| getTokenIndex | | public int getTokenIndex()(Code) | | |
| hasMoreTokens | | public boolean hasMoreTokens()(Code) | | Tests if there are more tokens available from this tokenizer's string. If this method returns true,
then a subsequent call to nextToken with no argument will successfully return a token.
true if and only if there is at least one token in the string after the current position;false otherwise. |
| isQuotesEnabled | | public boolean isQuotesEnabled()(Code) | | Determines if this tokenizer is sensitive to quoted strings.
true if this instance is sensitive to quotes for each token. |
| nextToken | | public String nextToken()(Code) | | Returns the next token from this string tokenizer.
the next token from this string tokenizer.
exception:
NoSuchElementException - if there are no more tokens in this tokenizer's string. |
| nextToken | | public String nextToken(String delim)(Code) | | Returns the next token in this string tokenizer's string. First, the set of characters considered to be
delimiters by this StringTokenizer object is changed to be the characters in the string delim.
Then the next token in the string after the current position is returned. The current position is advanced beyond
the recognized token. The new delimiter set remains the default after this call.
Parameters:
delim - the new delimiters. the next token, after switching to the new delimiter set.
exception:
NoSuchElementException - if there are no more tokens in this tokenizer's string.
exception:
NullPointerException - if delim is null |
| setQuotesEnabled | | public void setQuotesEnabled(boolean quotesEnabled)(Code) | | Sets quotes enabled for determining tokenzation.
Parameters:
quotesEnabled - flag to enable/disable quote sensitivity during tokenization. |
