Detailed Description

A simple wrapper for std::string which is derived from UObject.

Uses implicit data sharing. Implements some usefule functions like toString(Type & T), tokenize(), unsigned int hash(const char*), etc.

Member Function Documentation

const char * ufo::UString::c_str (   )  const [inline]

Returns a const char pointer to the shared string object.

virtual UObject* ufo::UString::clone (   )  const [virtual]

tries to make a new object with the same internal data. Reimplemented from ufo::UObject.

void ufo::UString::detach (   )

Creates a local copy of the shared string.

virtual bool ufo::UString::equals (  const UObject *  obj  )  const [virtual]

checks if this object is the same object than obj Reimplemented from ufo::UObject.

virtual bool ufo::UString::equals (  const UString *  str  )  const [virtual]

checks if this object is the same object than obj

unsigned int ufo::UString::hash (  const char *  cstr  )  [static]

Computes a hash value using horner's rule.

virtual unsigned int ufo::UString::hashCode (   )  const [virtual]

returns a std::size_t which is used when UObject pointers are the keys for UHashMap. If equals(UObject*) returns true, these two objects should return the same hash code. If these objects are different, the hash code may be equal. Returns: a hash code. Reimplemented from ufo::UObject.

UString ufo::UString::lowerCase (   )  const

Returns a new string with all characters in lower case.

virtual std::ostream& ufo::UString::paramString (  std::ostream &  os  )  const [protected, virtual]

Prints some useful internal data to the ostream os. This method is meant only for debugging purposes. Reimplemented from ufo::UObject.

std::string & ufo::UString::str (   )  [inline]

Returns a reference to the internal string. Be careful, this changes the internal string for all UString objects which are using the shared string. Use detach() if you want to modify only this UString object. This string should not be stored as it may be invalid when the UString objet gets out of scope. See also: detach

const std::string & ufo::UString::str (   )  const [inline]

Returns a const ref to the internal string. This string should not be stored as it may be invalid when the UString objet gets out of scope.

std::vector<std::string> ufo::UString::tokenize (  char  delimiter  )  const

The string is cut at every occurence of the character delimiter. The resulting array of strings (without delimiter) is returned. Returns: A tokenized vector of strings.

virtual std::string ufo::UString::toString (   )  const [virtual]

Returns only the string Reimplemented from ufo::UObject.

template<typename TYPE> std::string ufo::UString::toString (  const TYPE &  t  )  [static]

returns a string representation of the given type

UString ufo::UString::upperCase (   )  const

Returns a new string with all characters in upper case.
