Constructor & Destructor Documentation

skStringTokenizer::skStringTokenizer (  const skString &  str, const skString &  delim, bool  returnDelims )

Constructs a string tokenizer for the specified string. All characters in the delim argument are the delimiters for separating tokens. Remarks: not available in Symbian version

skStringTokenizer::skStringTokenizer (  const skString &  str, const skString &  delim )

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. Remarks: not available in Symbian version Parameters: str  a string to be parsed. delim  the delimiters.

skStringTokenizer::skStringTokenizer (  const skString &  str  )

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. Remarks: not available in Symbian version Parameters: str  a string to be parsed.

Member Function Documentation

int skStringTokenizer::countTokens (   )

Calculates the number of times that this tokenizer's nextToken method can be called. The current position is not advanced. Returns: the number of tokens remaining in the string using the current delimiter set.

bool skStringTokenizer::hasMoreTokens (   )

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. Returns: true if and only if there is at least one token in the string after the current position; false otherwise.

void skStringTokenizer::init (  const skString &  str, const skString &  delim, bool  returnDelims )

Initialize the tokenizer. Parameters: str  a string to be parsed. delim  the delimiters. returnDelims  flag indicating whether to return the delimiters as tokens. Exceptions: Symbian  - a leaving function

skString skStringTokenizer::nextToken (  const skString &  delim  )

Returns the next token in this string tokenizer's string. First, the set of characters considered to be delimiters by this skStringTokenizer 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. Returns: the next token, after switching to the new delimiter set. Exceptions: Symbian  - a leaving function

skString skStringTokenizer::nextToken (   )

Returns the next token from this string tokenizer. Returns: the next token from this string tokenizer. Exceptions: Symbian  - a leaving function
