Detailed Description

Class to store unicode strings. String stores 16bit unicode characters. Any characters are legal, including 0C (strings are not null-terminated). Strings 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.

◆ MAXON_INTERFACE_NONVIRTUAL()

MAXON_INTERFACE_NONVIRTUAL	(	StringInterface	,

		"net.maxon.interface.string"	,
		MAXON_IMPLEMENTATION_MODULE("net.maxon.kernel")
	)

◆ GetCStringBlock()

MAXON_METHOD Result<Int> GetCStringBlock	(	const Block< Char > &	buffer,
		const StringEncodingRef &	stringEncoding = `GetUtf8DefaultEncoder()`
	)		const

Converts a unicode string to a 8-bit encoded character string and copies it into buffer. The buffer size is taken into account.

Parameters

[in,out]	buffer	Block describing the buffer. A \0 byte will be appended to the string in any case.
[in]	stringEncoding	Encoding for the string. By default UTF-8 is selected. If a nullptr is passed the data is truncated to Char and no conversion takes place.

Returns: The length of the corresponding 8-bit string for the given encoding. The \0 byte is excluded.

◆ GetCStringAppendArray()

MAXON_METHOD Result<void> GetCStringAppendArray	(	const NonConstArray< Char > &	array,
		const StringEncodingRef &	stringEncoding = `GetUtf8DefaultEncoder()`
	)		const

Converts a unicode string to a 8-bit encoded character string and appends it to the given array.

Parameters

[in,out]	array	Array to be filled with the encoded string. The array is NOT terminated with a \0 byte.
[in]	stringEncoding	Encoding for the string. By default UTF-8 is selected. If a nullptr is passed the data is truncated to Char and no conversion takes place.

Returns: OK on success.

◆ GetCString()

MAXON_METHOD Result<BaseArray<Char> > GetCString ( const StringEncodingRef & stringEncoding = GetUtf8DefaultEncoder() ) const

Converts a unicode string to a 8-bit encoded character string and returns a new BaseArray<>.

Parameters

[in] stringEncoding Encoding for the string. By default UTF-8 is selected. If a nullptr is passed the data is truncated to Char and no conversion takes place.

Returns: BaseArray<Char> with the encoded string. The string is \0 - terminated, but the array size is equal to the string length without the \0 character.

◆ SetCString() [1/2]

MAXON_METHOD Result<void> SetCString	(	const Char *	buffer,
		Int	count = `-1`,
		const StringDecodingRef &	stringDecoding = `GetUtf8DefaultDecoder()`
	)

Initializes the string with a given 8-bit Char string with the given encoding.

Parameters

[out]	buffer	Pointer to the 8-bit character string.
[in]	count	Number of valid characters in the buffer, a value of -1 automatically detects the string length by searching for the first \0 character, otherwise count is relevant and not \0.
[in]	stringDecoding	DECODING for the string. By default UTF-8 is selected. If a nullptr is passed the data is copied 1:1.

Returns: OK on success.

◆ SetCString() [2/2]

MAXON_FUNCTION Result<void> SetCString	(	const Block< const Char > &	buffer,
		const StringDecodingRef &	stringDecoding = `GetUtf8DefaultDecoder()`
	)

Initializes the string with a given 8-bit Char string with the given encoding.

Parameters

[out]	buffer	Block with an 8-bit character string.
[in]	stringDecoding	DECODING for the string. By default UTF-8 is selected. If a nullptr is passed the data is copied 1:1.

Returns: OK on success.

◆ GetSystemEncoding()

MAXON_METHOD Result<SysCharArray> GetSystemEncoding ( ) const

Returns a copy of the string as a system-specific character array. The string will be \0 - terminated. GetFirst() on that call always return a valid pointer, even if the string length is 0! GetLength() returns the real string length without the trailing \0.

SysCharArray converted = str.GetSystemEncoding() iferr_return;

iferr_return

#define iferr_return

Definition: resultbase.h:1511

Returns: A copy of the character string.

◆ SetSystemEncoding()

MAXON_METHOD Result<void> SetSystemEncoding	(	const SysChar *	buffer,
		Int	count = `-1`
	)

Initializes the String with the given system-specific character string.

Parameters

[in]	buffer	Pointer to the buffer with the string.
[in]	count	Number of valid characters in the buffer. A count of -1 calculates the string length automatically, terminating when \0 is found.

Returns: OK on success.

◆ SetUtf32()

MAXON_METHOD Result<void> SetUtf32	(	const Utf32Char *	buffer,
		Int	count = `-1`
	)

Initializes the String with the given 32-bit unicode character string.

Parameters

[in]	buffer	Pointer to the buffer with the string.
[in]	count	Number of valid characters in the buffer. A count of -1 calculates the string length automatically, terminating when \0 is found.

Returns: OK on success.

◆ GetUtf16()

MAXON_METHOD Result<void> GetUtf16 ( Utf16CharBuffer & stringData ) const

Copies the string as UTF-16 encoded characters into the passed array. The array will be resized and contain the non \0 - terminated data.

Parameters

[out] stringData The array to receive the data.

Returns: OK on success.

◆ SetUtf16()

MAXON_METHOD Result<void> SetUtf16	(	const Utf16Char *	buffer,
		Int	count = `-1`
	)

Initializes the String with the given 16-bit unicode character string.

Parameters

[in]	buffer	Pointer to the buffer with the string.
[in]	count	Number of valid characters in the buffer. A count of -1 calculates the string length automatically, terminating when \0 is found.

Returns: OK on success.

◆ GetAndCacheConstString() [1/2]

static MAXON_METHOD const String& GetAndCacheConstString	(	const wchar_t *	chr,
		Int	len
	)

static

Internal. Caches a static constant string and returns a maxon::String.

◆ GetAndCacheConstString() [2/2]

static MAXON_METHOD const String& GetAndCacheConstString	(	const Char *	chr,
		Int	len,
		Int	isUtf8
	)

static

Internal. Caches a static constant string and returns a maxon::String.

◆ GetAndCacheConstStringT()

static MAXON_ATTRIBUTE_FORCE_INLINE const String& GetAndCacheConstStringT	(	const T *	chr,
		Int	len,
		Int	isUtf8

Internal. Converts the given enum value to a string.

Parameters

[in]	info	The EnumInfo to use.
[in]	value	The enum value, converted to UInt64.
[in]	formatStatement	Nullptr or additional formatting instruction. Currently no additional formatting instructions are supported.

◆ GetVariableInternalData()

MAXON_METHOD StridedBlock<const Generic> GetVariableInternalData ( ) const

Returns the internal character array. Temporarily renamed.

Returns: Block describing the internal character buffer. The data is read only! Please note that GetCount() will return the number of characters (and not bytes).

◆ GetCharacterWidth()

MAXON_METHOD Int GetCharacterWidth ( ) const

Retrieves the string's character width. The width determines the result of GetInternalDataX().

Returns: 1, 2 or 4 (bytes).

◆ ConvertString()

MAXON_FUNCTION Result<String> ConvertString ( const SCR & converter ) const

Converts a string using a UTF32 -> UTF32 encoder or decoder (e.g. StringEncodings::Url32).

Parameters

[in] converter String encoder or decoder that should be applied to the conversion.

Returns: The converted string.

◆ Prettify()

MAXON_METHOD Result<String> Prettify	(	Int	indent = `0`,
		const String &	indentStr = `CONSTSTRING("\t")`,
		Int	breakUpThreshold = `100`,
		Bool	angularBrackets = `false`
	)		const

Returns a "prettified" version of this string where line breaks and indentations are added according to parentheses and commas.

Parameters

[in]	indent	The initial indent to use.
[in]	indentStr	The indentation string to use, a tab character by default.
[in]	breakUpThreshold	The maximum number of characters which shall be kept in a single line, 100 by default.
[in]	angularBrackets	When true, also angular brackets are handled. When false, only normal parentheses, curly and square brackets are considered.

Returns: The converted string.

◆ MAXON_ADD_TO_COPY_ON_WRITE_REFERENCE_CLASS()
