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() [1/6]

SbString::SbString ( void  )

inline

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

SbString() [2/6]

SbString::SbString ( const char *  str )

inline

This constructor assigns from the given string.

SbString() [3/6]

SbString::SbString ( const wchar_t *  str )

inline

This constructor converts the given string to UTF-8 and assigns it.

SbString() [4/6]

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() [5/6]

SbString::SbString ( const SbString &  str )

inline

This is the copy constructor.

SbString() [6/6]

SbString::SbString ( const int  digits )

inline

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

~SbString()

SbString::~SbString ( )

inline

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

Member Function Documentation

hash() [1/2]

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)

hash() [2/2]

uint32_t SbString::hash ( const char *  s )

inlinestatic

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

getLength()

int SbString::getLength ( void  ) const

inline

This method returns the length of the string.

makeEmpty()

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.

getString()

const char * SbString::getString ( void  ) const

inline

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

getSubString()

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 endidx (inclusive).

If endidx is -1, the substring from startidx to the end of the string is used.

This will return a string which is (endidx - 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/".

deleteSubString()

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.

addIntString()

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.

operator[]()

char SbString::operator[] ( int  index ) const

inline

Returns character at position index in the string.

See also

getSubString()

operator=() [1/2]

SbString & SbString::operator= ( const char *  str )

inline

This is the assignment operator.

operator=() [2/2]

SbString & SbString::operator= ( const SbString &  str )

inline

Assign from the given string.

operator+=() [1/3]

SbString & SbString::operator+= ( const char *  str )

inline

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

operator+=() [2/3]

SbString & SbString::operator+= ( const SbString &  str )

inline

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

operator+=() [3/3]

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.

operator!()

int SbString::operator! ( void  ) const

inline

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

compareSubString()

int SbString::compareSubString ( const char *  text, int  offset = 0  ) const

inline

Uses text as a substring to be compared to the string, starting at offset offset. Return value is 0 upon success, and the failing character comparison difference upon failure.

sprintf()

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.

vsprintf()

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.

find()

int SbString::find

(

const SbString &

strarg

)

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

findAll()

SbBool SbString::findAll	(	const SbString &	strarg,
		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.

SbString::find()

Since

Coin 2.0

lower()

SbString SbString::lower

(

)

const

Converts all of the characters to lowercase using tolower().

Since

Coin 3.1

upper()

SbString SbString::upper

(

)

const

Converts all of the characters to uppercase using toupper().

Since

Coin 3.1

print()

void SbString::print

(

std::FILE *

fp

)

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.
