## Detailed Description

The SbString class is a string class with convenience functions for string operations.

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.

## Constructor & Destructor Documentation

SbString::SbString | ( | void |  | ) | `[inline]`

| This is the default constructor. It initializes the string to be empty.

SbString::SbString | ( | const char * | str | ) | `[inline]`

| This constructor assigns from the given string.

SbString::SbString | ( | const char * | str,
|  | int | start,
|  | int | end
| ) | `[inline]`

| 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 | ) | `[inline]`

| This is the copy constructor.

SbString::SbString | ( | const int | digits | ) | `[inline]`

| Construct an SbString instance containing the digits of the integer argument.

SbString::~SbString | ( |  | ) | `[inline]`

| The destructor. Deallocates any internal resources used during the lifetime of the SbString instance.

## Member Function Documentation

uint32_t SbString::hash | ( | void |  | ) | const`[inline]`

| This method returns a reasonable hash value for the current string. See also: uint32_t SbString::hash(const char * s)

uint32_t SbString::hash | ( | const char * | s | ) | `[inline, static]`

| This static method returns a hash value for the given string.

int SbString::getLength | ( | void |  | ) | const`[inline]`

| This method returns the length of the string.

void SbString::makeEmpty | ( | SbBool | freeold = TRUE | ) | `[inline]`

| 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`[inline]`

| This method returns the pointer to the string (character array).

SbString SbString::getSubString | ( | int | startidx,
|  | int | endidx = -1
| ) | const`[inline]`

| 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
| ) | `[inline]`

| 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 | ) | `[inline]`

| 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`[inline]`

| Returns character at position index in the string. See also: getSubString()

SbString & SbString::operator= | ( | const char * | str | ) | `[inline]`

| This is the assignment operator.

SbString & SbString::operator= | ( | const SbString & | str | ) | `[inline]`

| Assign from the given string.

SbString & SbString::operator+= | ( | const char * | str | ) | `[inline]`

| Concatenate the given string to the end of the current one.

SbString & SbString::operator+= | ( | const SbString & | str | ) | `[inline]`

| Concatenate the given string to the end of the current one.

SbString & SbString::operator+= | ( | const char | c | ) | `[inline]`

| Concatenate the given character to the end of the current string. Note: This member function is not compatible with OpenInventor.

int SbString::operator! | ( | void |  | ) | const`[inline]`

| This unary operator results in `TRUE` if the current string is empty ("") or `FALSE` otherwise.

SbString & SbString::sprintf | ( | const char * | formatstr,
|  | ... |
| ) | `[inline]`

| 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
| ) | `[inline]`

| 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.

int SbString::find | ( | const SbString & | str | ) | const

| If s is found, the method returns the first index where s starts. Otherwise it returns -1. Note: SbString::find() is a Coin specific extension to the original Open Inventor API. See also: SbString::findAll() Since: Coin 2.0

SbBool SbString::findAll | ( | const SbString & | str,
|  | SbIntList & | found
| ) | const

| All occurences of str is represented in found as indices to the characters where str starts. If 1 or more is found, `TRUE` is returned, else `FALSE` is returned. Note: SbString::findAll() is an extension to the original Open Inventor API. See also: SbString::find() Since: Coin 2.0
