Description¶

TStringStream stores its data in an ansistring. The contents of this string is available as the DataString property. It also introduces some methods to read or write parts of the stringstream's data as a string.

The main purpose of a TStringSTream is to be able to treat a string as a stream from which can be read.

Properties¶

Encoding read only	public	Encoding of the string with the data.
OwnsEncoding read only	public	Does the stream instance owns the encoding.
UnicodeDataString read only	public	Datastring as unicode string.
