CString Class Reference

#include <string.h>

Inheritance diagram for CString:

Detailed Description

Class to store 8 bit strings. The CString stores 8 bit characters. Any characters are legal, including 0C (for example CString("\0\0\0\0", 4) will result in a CString with length 4). CStrings are reference-counted objects. This means that as long as you copy and do not modify strings they are just referenced. The first modification breaks the link and it becomes a unique new object. For error handling see String.

Constructor & Destructor Documentation

CString() [1/4]

CString ( const Char *  str, Int  count = -1  )

explicit

Constructor for Char array. If you have static Char strings use "..."_cs instead.

Parameters

[in]	str	C string block.
[in]	count	Number of characters, -1 to auto detect the length of the string (search for the first 0).

CString() [2/4]

CString ( Int  count, Char  fillChar  )

explicit

Constructor to create a string with a specific length and a default character.

Parameters

[in]	count	Number of characters of the new string.
[in]	fillChar	Character to fill the string with.

CString() [3/4]

CString ( const Block< const Char > &  str )

explicit

Constructor from a Char Block. If you have static strings use "..."_cs instead.

Parameters

[in]

str

Char block, for example a BaseArray<Char>.

CString() [4/4]

CString ( const String &  str, const StringEncodingRef &  stringEncoding = GetUtf8DefaultEncoder()  )

explicit

Constructor to create a CString from a String. The lower byte of each character will be copied, whereas the upper byte will be discarded.

Parameters

[in]	str	Unicode string.
[in]	stringEncoding	Encoding for the string. By default utf8 is selected. If a nullptr is passed the data is truncated to Char and no conversion takes place.

operator[]() [1/2]

Char operator[]

(

Int

pos

)

const

Index operator to access single characters of the string.

Parameters

[in]

pos

Position within the string the first character starts with an index of 0. If the position is out of boundaries 0 will be returned.

Returns

Utf32Char for read (right of =), Utf32Char& for write (left of =).

operator[]() [2/2]

MAXON_ATTRIBUTE_FORCE_INLINE CStringInterface::CharPtr operator[]

(

Int

position

)

Index operator to access single characters of the string.

Parameters

[in]

position

Position within the string the first character starts with an index of 0. if the position is out of boundaries no changes will be made.

Returns

Utf32Char for read (right of =), Utf32Char& for write (left of =).

Begin()

ConstIterator Begin

End()

ConstIterator End

(

)

const

IsEmpty()

Bool IsEmpty

(

)

const

Returns if the string length is zero.

Returns

True if the string doesn't contain any character, or if it is a nullptr.

IsPopulated()

Bool IsPopulated

(

)

const

Returns if the string contains any characters.

Returns

True if the string contains any character.

operator+=()

CString& operator+=

(

const CString &

str

)

operator const Char *()

operator const Char *

(

)

const

Conversion to const Char*, returns the pointer to a null-terminated C string.

Returns

Pointer to null terminated C string (can never be a nullptr).

operator Block< const Char >()

operator Block< const Char >

(

)

const

Converts this CString to a block of characters. The null-terminator isn't part of the block.

Returns

Block of characters of this CString.

ToBlock()

Block<const Char> ToBlock

(

)

const

Converts this CString to a block of characters. The null-terminator isn't part of the block.

Returns

Block of characters of this CString.

GetLineEnd()

static const CString& GetLineEnd ( )

static

Returns a string with the platform specific line ending.

Returns

String containing the line ending ("\r\n" or "\n").
