Public Member Functions inherited from XMemory | |
void * | operator new (size_t size) |
This method overrides operator new. | |
void * | operator new (size_t size, MemoryManager *memMgr) |
This method defines a custom operator new, that will use the provided memory manager to perform the allocation. | |
void * | operator new (size_t size, void *ptr) |
This method overrides placement operator new. | |
void | operator delete (void *p) |
This method overrides operator delete. | |
void | operator delete (void *p, MemoryManager *memMgr) |
This method provides a matching delete for the custom operator new. | |
void | operator delete (void *p, void *ptr) |
This method provides a matching delete for the placement new. | |
Management Function | |
bool | hasMoreTokens () |
Tests if there are more tokens available from this tokenizer's string. | |
unsigned int | countTokens () |
Calculates the number of times that this tokenizer's nextToken method can be called to return a valid token. | |
XMLCh * | nextToken () |
Returns the next token from this string tokenizer. | |

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.
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.
srcStr | The string to be parsed. |
manager | Pointer 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.
srcStr | The string to be parsed. |
delim | The set of delimiters. |
manager | Pointer to the memory manager to be used to allocate objects. |
XMLStringTokenizer::~XMLStringTokenizer | ( | ) |
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.
