Detailed Description

The QStringRef class provides a thin wrapper around QString substrings.

QStringRef provides a read-only subset of the QString API.

A string reference explicitly references a portion of a string() with a given size(), starting at a specific position(). Calling toString() returns a copy of the data as a real QString instance.

This class is designed to improve the performance of substring handling when manipulating substrings obtained from existing QString instances. QStringRef avoids the memory allocation and reference counting overhead of a standard QString by simply referencing a part of the original string. This can prove to be advantageous in low level code, such as that used in a parser, at the expense of potentially more complex code.

For most users, there are no semantic benefits to using QStringRef instead of QString since QStringRef requires attention to be paid to memory management issues, potentially making code more complex to write and maintain.

Warning: A QStringRef is only valid as long as the referenced string exists. If the original string is deleted, the string reference points to an invalid memory location.

We suggest that you only use this class in stable code where profiling has clearly identified that performance improvements can be made by replacing standard string operations with the optimized substring handling provided by this class.

Constructor & Destructor Documentation

QtCore.QStringRef.QStringRef ( System.Type  dummy )

protected

QtCore.QStringRef.QStringRef

(

)

Constructs an empty string reference.

QtCore.QStringRef.QStringRef

(

QStringRef

other

)

Constructs a copy of the other string reference.

QtCore.QStringRef.QStringRef

(

System.Text.StringBuilder @

string

)

Constructs a string reference to the given string.

QtCore.QStringRef.QStringRef	(	System.Text.StringBuilder @	string,
		int	position,
		int	size
	)

Constructs a string reference to the range of characters in the given string specified by the starting position and length in characters.

Warning: This function exists to improve performance as much as possible, and performs no bounds checking. For program correctness, position and length must describe a valid substring of string.

This means that the starting position must be positive or 0 and smaller than string's length, and length must be positive or 0 but smaller than the string's length minus the starting position; i.e, 0 <= position < string->length() and 0 <= length <= string->length() - position must both be satisfied.

See also QString::startsWith() and endsWith().

new System.Text.StringBuilder QtCore.QStringRef.String

(

)

Returns a pointer to the string referred to by the string reference, or 0 if it does not reference a string.

See also unicode().

new QByteArray QtCore.QStringRef.ToAscii

(

)

Returns an 8-bit representation of the string as a QByteArray.

If a codec has been set using QTextCodec::setCodecForCStrings(), it is used to convert Unicode to 8-bit char; otherwise this function does the same as toLatin1().

Note that, despite the name, this function does not necessarily return an US-ASCII (ANSI X3.4-1986) string and its result may not be US-ASCII compatible.

This function was introduced in Qt 4.8.

See also toLatin1(), toUtf8(), toLocal8Bit(), and QTextCodec.

new QByteArray QtCore.QStringRef.ToLatin1

(

)

Returns a Latin-1 representation of the string as a QByteArray.

The returned byte array is undefined if the string contains non-Latin1 characters. Those characters may be suppressed or replaced with a question mark.

This function was introduced in Qt 4.8.

See also toAscii(), toUtf8(), toLocal8Bit(), and QTextCodec.

new QByteArray QtCore.QStringRef.ToLocal8Bit

(

)

Returns the local 8-bit representation of the string as a QByteArray. The returned byte array is undefined if the string contains characters not supported by the local 8-bit encoding.

QTextCodec::codecForLocale() is used to perform the conversion from Unicode. If the locale encoding could not be determined, this function does the same as toLatin1().

If this string contains any characters that cannot be encoded in the locale, the returned byte array is undefined. Those characters may be suppressed or replaced by another.

This function was introduced in Qt 4.8.

See also toAscii(), toLatin1(), toUtf8(), and QTextCodec.

override string QtCore.QStringRef.ToString

(

)

Returns a copy of the string reference as a QString object.

If the string reference is not a complete reference of the string (meaning that position() is 0 and size() equals string()->size()), this function will allocate a new string to return.

See also string().

new System.Collections.Generic.List<System.UInt32> QtCore.QStringRef.ToUcs4

(

)

Returns a UCS-4/UTF-32 representation of the string as a QVector<uint>.

UCS-4 is a Unicode codec and is lossless. All characters from this string can be encoded in UCS-4.

This function was introduced in Qt 4.8.

See also toAscii(), toLatin1(), toLocal8Bit(), and QTextCodec.

new QByteArray QtCore.QStringRef.ToUtf8

(

)

Returns a UTF-8 representation of the string as a QByteArray.

UTF-8 is a Unicode codec and can represent all characters in a Unicode string like QString.

However, in the Unicode range, there are certain codepoints that are not considered characters. The Unicode standard reserves the last two codepoints in each Unicode Plane (U+FFFE, U+FFFF, U+1FFFE, U+1FFFF, U+2FFFE, etc.), as well as 16 codepoints in the range U+FDD0..U+FDDF, inclusive, as non-characters. If any of those appear in the string, they may be discarded and will not appear in the UTF-8 representation, or they may be replaced by one or more replacement characters.

This function was introduced in Qt 4.8.

See also toAscii(), toLatin1(), toLocal8Bit(), and QTextCodec.

new QChar QtCore.QStringRef.Unicode

(

)

Returns a Unicode representation of the string reference. Since the data stems directly from the referenced string, it is not null-terminated unless the string reference includes the string's null terminator.
