CString Class Reference 系统

#include <string.h>

Inheritance diagram for CString:

[ legend ]

详细描述

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 .

构造函数 & 析构函数文档编制

◆  CString() [1/4]

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

参数

[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]

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

参数

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

◆  CString() [3/4]

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

参数

[in]

str

Char block, for example a BaseArray<Char> .

◆  CString() [4/4]

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

参数

[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.

成员函数文档编制

◆  MAXON_DEFAULT_REFERENCE_CONSTRUCTORS()

◆  operator[]() [1/2]

Index operator to access single characters of the string.

参数

[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.

返回

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

◆  operator[]() [2/2]

Index operator to access single characters of the string.

参数

[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.

返回

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

◆  Begin()

◆  End()

◆  IsEmpty()

Returns if the string length is zero.

返回

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

◆  IsPopulated()

Returns if the string contains any characters.

返回

True if the string contains any character.

◆  operator+=()

◆  operator const Char *()

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

返回

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

◆  operator Block< const Char >()

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

返回

Block of characters of this CString .

◆  GetLineEnd()

Returns a string with the platform specific line ending.

返回

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

◆  operator->()
