	Initializes a HAsciiString with a HAsciiString.

	TCollection_HAsciiString (const Handle< TCollection_HExtendedString > &aString, const Standard_Character replaceNonAscii)
	Initializes a HAsciiString with a HExtendedString. If replaceNonAscii is non-null character, it will be used in place of any non-ascii character found in the source string. Otherwise, creates UTF-8 unicode string.

void	AssignCat (const Standard_CString other)
	Appends <other> to me.

void	AssignCat (const Handle< TCollection_HAsciiString > &other)
	Appends <other> to me. Example: aString = aString + anotherString.

void	Capitalize ()
	Converts the first character into its corresponding upper-case character and the other characters into lowercase. Example: before me = "hellO " after me = "Hello ".

Handle< TCollection_HAsciiString >	Cat (const Standard_CString other) const
	Creates a new string by concatenation of this ASCII string and the other ASCII string. Example: aString = aString + anotherString aString = aString + "Dummy" aString contains "I say " aString = aString + "Hello " + "Dolly" gives "I say Hello Dolly" Warning: To catenate more than one CString, you must put a String before. So the following example is WRONG ! aString = "Hello " + "Dolly" THIS IS NOT ALLOWED This rule is applicable to AssignCat (operator +=) too.

Handle< TCollection_HAsciiString >	Cat (const Handle< TCollection_HAsciiString > &other) const
	Creates a new string by concatenation of this ASCII string and the other ASCII string. Example: aString = aString + anotherString.

void	Center (const Standard_Integer Width, const Standard_Character Filler)
	Modifies this ASCII string so that its length becomes equal to Width and the new characters are equal to Filler. New characters are added both at the beginning and at the end of this string. If Width is less than the length of this ASCII string, nothing happens. Example Handle(TCollection_HAsciiString) myAlphabet = new TCollection_HAsciiString ("abcdef"); myAlphabet->Center(9,' '); assert ( !strcmp( myAlphabet->ToCString(), " abcdef ") );.

void	ChangeAll (const Standard_Character aChar, const Standard_Character NewChar, const Standard_Boolean CaseSensitive=Standard_True)
	Replaces all characters equal to aChar by NewChar in this ASCII string. The substitution is case sensitive if CaseSensitive is true (default value). If you do not use the default case sensitive option, it does not matter whether aChar is upper-case or not. Example Handle(TCollection_HAsciiString) myMistake = new TCollection_HAsciiString ("Hather"); myMistake->ChangeAll('H','F'); assert ( !strcmp( myMistake->ToCString(), "Father") );.

Detailed Description

A variable-length sequence of ASCII characters (normal 8-bit character type). It provides editing operations with built-in memory management to make HAsciiString objects easier to use than ordinary character arrays. HAsciiString objects are handles to strings.

HAsciiString strings may be shared by several objects.
You may use an AsciiString object to get the actual string. Note: HAsciiString objects use an AsciiString string as a field.

◆ RemoveAll() [1/2]

void TCollection_HAsciiString::RemoveAll	(	const Standard_Character	C,
		const Standard_Boolean	CaseSensitive )

Remove all the occurrences of the character C in the string Example: before me = "HellLLo", C = 'L' , CaseSensitive = True after me = "Hello".

◆ RemoveAll() [2/2]

void TCollection_HAsciiString::RemoveAll ( const Standard_Character what )

Removes every <what> characters from <me>

◆ RightAdjust()

void TCollection_HAsciiString::RightAdjust ( )

Removes all space characters at the end of the string.

◆ RightJustify()

void TCollection_HAsciiString::RightJustify	(	const Standard_Integer	Width,
		const Standard_Character	Filler )

Right justify. Length becomes equal to Width and the new characters are equal to Filler if Width < Length nothing happens Raises an exception if Width is less than zero Example: before me = "abcdef" , Width = 9 , Filler = ' ' after me = " abcdef".

◆ Search() [1/2]

Standard_Integer TCollection_HAsciiString::Search ( const Handle< TCollection_HAsciiString > & what ) const

Searches a String in <me> from the beginning and returns position of first item <what> matching. it returns -1 if not found.

◆ Search() [2/2]

Standard_Integer TCollection_HAsciiString::Search ( const Standard_CString what ) const

Searches a CString in <me> from the beginning and returns position of first item <what> matching. It returns -1 if not found. Example: aString contains "Sample single test" aString.Search("le") returns 5.

◆ SearchFromEnd() [1/2]

Standard_Integer TCollection_HAsciiString::SearchFromEnd ( const Handle< TCollection_HAsciiString > & what ) const

Searches a HAsciiString in another HAsciiString from the end and returns position of first item <what> matching. It returns -1 if not found.

◆ SearchFromEnd() [2/2]

Standard_Integer TCollection_HAsciiString::SearchFromEnd ( const Standard_CString what ) const

Searches a CString in a String from the end and returns position of first item <what> matching. It returns -1 if not found. Example: aString contains "Sample single test" aString.SearchFromEnd("le") returns 12.

◆ SetValue() [1/3]

void TCollection_HAsciiString::SetValue	(	const Standard_Integer	where,
		const Handle< TCollection_HAsciiString > &	what )

Replaces a part of <me> by another string.

◆ SetValue() [2/3]

void TCollection_HAsciiString::SetValue	(	const Standard_Integer	where,
		const Standard_Character	what )

Replaces one character in the string at position <where>. If <where> is less than zero or greater than the length of <me> an exception is raised. Example: aString contains "Garbake" astring.Replace(6,'g') gives <me> = "Garbage".

◆ SetValue() [3/3]

void TCollection_HAsciiString::SetValue	(	const Standard_Integer	where,
		const Standard_CString	what )

Replaces a part of <me> in the string at position <where>. If <where> is less than zero or greater than the length of <me> an exception is raised. Example: aString contains "Garbake" astring.Replace(6,'g') gives <me> = "Garbage".

◆ Split()

Handle< TCollection_HAsciiString > TCollection_HAsciiString::Split ( const Standard_Integer where )

Splits a HAsciiString into two sub-strings. Example: aString contains "abcdefg" aString.Split(3) gives <me> = "abc" and returns "defg".

◆ String()

const TCollection_AsciiString & TCollection_HAsciiString::String ( ) const

Returns the field myString.

◆ SubString()

Handle< TCollection_HAsciiString > TCollection_HAsciiString::SubString	(	const Standard_Integer	FromIndex,
		const Standard_Integer	ToIndex ) const

Creation of a sub-string of the string <me>. The sub-string starts to the index Fromindex and ends to the index ToIndex. Raises an exception if ToIndex or FromIndex is out of bounds Example: before me = "abcdefg", ToIndex=3, FromIndex=6 after me = "abcdefg" returns "cdef".

◆ ToCString()

Standard_CString TCollection_HAsciiString::ToCString ( ) const

Returns pointer to string (char *) This is useful for some casual manipulations Because this "char *" is 'const', you can't modify its contents.

◆ Token()

Handle< TCollection_HAsciiString > TCollection_HAsciiString::Token	(	const Standard_CString	separators = " \t",
		const Standard_Integer	whichone = 1 ) const

Extracts <whichone> token from <me>. By default, the <separators> is set to space and tabulation. By default, the token extracted is the first one (whichone = 1). <separators> contains all separators you need. If no token indexed by <whichone> is found, it returns an empty String. Example: aString contains "This is a message" aString.Token() returns "This" aString.Token(" ",4) returns "message" aString.Token(" ",2) returns "is" aString.Token(" ",9) returns "" Other separators than space character and tabulation are allowed aString contains "1234; test:message , value" aString.Token("; :,",4) returns "value" aString.Token("; :,",2) returns "test".

◆ Trunc()

void TCollection_HAsciiString::Trunc ( const Standard_Integer ahowmany )

Truncates <me> to <ahowmany> characters. Example: me = "Hello Dolly" -> Trunc(3) -> me = "Hel".

◆ UpperCase()

void TCollection_HAsciiString::UpperCase ( )

Converts <me> to its upper-case equivalent.

◆ UsefullLength()

Standard_Integer TCollection_HAsciiString::UsefullLength ( ) const

Length of the string ignoring all spaces (' ') and the control character at the end.

◆ Value()

Standard_Character TCollection_HAsciiString::Value ( const Standard_Integer where ) const

Returns character at position <where> in <me>. If <where> is less than zero or greater than the length of <me>, an exception is raised. Example: aString contains "Hello" aString.Value(2) returns 'e'.
