Detailed Description

The QByteArrayMatcher class holds a sequence of bytes that can be quickly matched in a byte array.

This class is useful when you have a sequence of bytes that you want to repeatedly match against some byte arrays (perhaps in a loop), or when you want to search for the same sequence of bytes multiple times in the same byte array. Using a matcher object and indexIn() is faster than matching a plain QByteArray with QByteArray::indexOf() if repeated matching takes place. This class offers no benefit if you are doing one-off byte array matches.

Create the QByteArrayMatcher with the QByteArray you want to search for. Then call indexIn() on the QByteArray that you want to search.

Constructor & Destructor Documentation

QtCore.QByteArrayMatcher.QByteArrayMatcher ( System.Type  dummy )

protected

QtCore.QByteArrayMatcher.QByteArrayMatcher

(

)

Constructs an empty byte array matcher that won't match anything. Call setPattern() to give it a pattern to match.

QtCore.QByteArrayMatcher.QByteArrayMatcher

(

QByteArray

pattern

)

Constructs a byte array matcher that will search for pattern. Call indexIn() to perform a search.

QtCore.QByteArrayMatcher.QByteArrayMatcher

(

QByteArrayMatcher

other

)

Copies the other byte array matcher to this byte array matcher.

QtCore.QByteArrayMatcher.QByteArrayMatcher	(	string	pattern,
		int	length
	)

Constructs a byte array matcher from pattern. pattern has the given length. pattern must remain in scope, but the destructor does not delete pattern.

Member Function Documentation

virtual void QtCore.QByteArrayMatcher.CreateProxy ( )

virtual

new void QtCore.QByteArrayMatcher.Dispose

(

)

new int QtCore.QByteArrayMatcher.IndexIn	(	QByteArray	ba,
		int	from = 0
	)

Searches the byte array ba, from byte position from (default 0, i.e. from the first byte), for the byte array pattern() that was set in the constructor or in the most recent call to setPattern(). Returns the position where the pattern() matched in ba, or -1 if no match was found.

new int QtCore.QByteArrayMatcher.IndexIn	(	string	str,
		int	len,
		int	from = 0
	)

Searches the char string str, which has length len, from byte position from (default 0, i.e. from the first byte), for the byte array pattern() that was set in the constructor or in the most recent call to setPattern(). Returns the position where the pattern() matched in str, or -1 if no match was found.
