Detailed Description

This input source can read characters from an unicode string, so no character conversion is performed, but the XML declaration is parsed.

Member Function Documentation

import()

std::streamsize import ( )

inherited

If no more characters can be read directly from the input stream buffer without blocking read operations, the virtual method onInput() is called. The number of available characters is returned, which can be 0 if no data is available.

init()

void init ( std::basic_streambuf< Char > *  rdbuf = 0, XmlDeclaration *  decl = 0  )

protectedinherited

The derived input sources must call this method once the XML or text declaration is parsed or if none was found. Normally, this is done in the virtual methods onGet() and onImport(), which are called by the public interface methods get() and import() when no buffer was set yet. The passed buffer and declaration are owned by the derived class.
