Detailed Description

The string tokenizer class breaks a string into tokens.

The XMLStringTokenizer methods do not distinguish among identifiers, numbers, and quoted strings, nor do they recognize and skip comments

A XMLStringTokenizer object internally maintains a current position within the string to be tokenized. Some operations advance this current position past the characters processed.

Constructor & Destructor Documentation

XMLStringTokenizer::XMLStringTokenizer ( const XMLCh *const  srcStr,
MemoryManager *const  manager = XMLPlatformUtils::fgMemoryManager 
)

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
srcStrThe string to be parsed.
managerPointer to the memory manager to be used to allocate objects.
XMLStringTokenizer::XMLStringTokenizer ( const XMLCh *const  srcStr,
const XMLCh *const  delim,
MemoryManager *const  manager = XMLPlatformUtils::fgMemoryManager 
)

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.

Parameters
srcStrThe string to be parsed.
delimThe set of delimiters.
managerPointer to the memory manager to be used to allocate objects.
XMLStringTokenizer::~XMLStringTokenizer ( )

Member Function Documentation

unsigned int XMLStringTokenizer::countTokens ( )

Calculates the number of times that this tokenizer's nextToken method can be called to return a valid token.

The current position is not advanced.

Returns the number of tokens remaining in the string using the current delimiter set.

bool XMLStringTokenizer::hasMoreTokens ( )

Tests if there are more tokens available from this tokenizer's string.

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

XMLCh* XMLStringTokenizer::nextToken ( )

Returns the next token from this string tokenizer.

Function allocated, function managed (fafm). The calling function does not need to worry about deleting the returned pointer.
