Internally for the Coin library, this is the class used for storing and working with character strings. It automatically takes care of supporting all the "bookkeeping" tasks usually associated with working with character strings, like memory allocation and deallocation etc.
This class should also be well suited for use by the application programmer throughout the application using the Coin library.
SbString::SbString | ( | void | ) |
This is the default constructor. It initializes the string to be empty.
SbString::SbString | ( | const char * | str | ) |
This constructor assigns from the given string.
SbString::SbString | ( | const char * | str, | |
int | start, | |||
int | end | |||
) |
This constructor constructs a string from the given substring from start to end indices inclusive. If end is -1, the substring from start until the end of the string is used.
SbString::SbString | ( | const SbString & | str | ) |
This is the copy constructor.
SbString::SbString | ( | const int | digits | ) |
Construct an SbString instance containing the digits of the integer argument.
SbString::~SbString | ( | ) |
The destructor.
uint32_t SbString::hash | ( | void | ) |
This method returns a reasonable hash value for the current string.
int SbString::getLength | ( | void | ) | const |
This method returns the length of the string.
void SbString::makeEmpty | ( | SbBool | freeold = TRUE |
) |
This method clears the string, making it an empty string (""). If freeold is TRUE
(which is the default), the memory used by the old string is freed. Otherwise, memory will be kept and reused when the string is manipulated later.
const char * SbString::getString | ( | void | ) | const |
This method returns the pointer to the string (character array).
SbString SbString::getSubString | ( | int | startidx, | |
int | endidx = -1 | |||
) | const |
This method returns a new string which contains a substring defined by the given indices startidx and endChar (inclusive). If endChar is -1, the substring from startidx to the end of the string is used.
This will return a string which is (endChar - startidx + 1) characters long, i.e. if this string is "foo/bar" and we call by SbString::getSubString(0, 3), the returned string will be "foo/".
void SbString::deleteSubString | ( | int | startidx, | |
int | endidx = -1 | |||
) |
This method deletes the substring defined by startidx and endidx (inclusive). If endidx is -1, the substring from startidx to the end of the string is deleted.
void SbString::addIntString | ( | const int | value | ) |
Constructs a string from the given integer (e.g. intToString(42) creates the string "42"), and adds this to the contents of the string.
char SbString::operator[] | ( | int | index | ) | const |
SbString & SbString::operator= | ( | const char * | str | ) |
This is the assignment operator.
SbString & SbString::operator+= | ( | const char * | str | ) |
Concatenate the given string to the end of the current one.
Concatenate the given string to the end of the current one.
int SbString::operator! | ( | void | ) | const |
This unary operator results in TRUE
if the current string is empty ("") or FALSE
otherwise.
uint32_t SbString::hash | ( | const char * | s | ) | [static] |
This static method returns a hash value for the given string.
SbString & SbString::operator+= | ( | const char | c | ) |
Concatenate the given character to the end of the current string.
SbString & SbString::sprintf | ( | const char * | formatstr, | |
... | ||||
) |
Set SbString instance to the formatted string formatstr, replacing the current contents. The control characters within formatstr and the remaining arguments should follow the conventions of the printf() call.
Note that this function is not part of the original Open Inventor API.
SbString & SbString::vsprintf | ( | const char * | formatstr, | |
va_list | args | |||
) |
Set SbString instance to the formatted string formatstr, replacing the current contents. The control characters within formatstr and the arguments of the args argument list should follow the conventions of the printf() call.
Note that this function is not part of the original Open Inventor API.
void SbString::print | ( | FILE * | file = stdout |
) | const |
Dump the state of this object to the file stream. Only works in debug version of library, method does nothing in an optimized compile.
int operator== | ( | const SbString & | str, | |
const char * | s | |||
) | [friend] |
Equality operator. Check if the strings have the same contents.
int operator== | ( | const char * | s, | |
const SbString & | str | |||
) | [friend] |
Equality operator. Check if the strings have the same contents.
Equality operator. Check if the strings have the same contents.
int operator!= | ( | const SbString & | str, | |
const char * | s | |||
) | [friend] |
Inequality operator.
int operator!= | ( | const char * | s, | |
const SbString & | str | |||
) | [friend] |
Inequality operator.
