Detailed Description

Subclass of instream for reading data from multiple files in a directory (as if they were all concatinated).

Constructor & Destructor Documentation

JASS::instream_directory_iterator::instream_directory_iterator ( const std::string & directory_name )

Constructor.

Parameters

directory_name [in] The name of the directory to search within

void JASS::instream_directory_iterator::read ( document & buffer )

virtual

Read buffer.contents.size() bytes of data into buffer.contents, resizing on eof.

Parameters

buffer [out] buffer.contents.size() bytes of data are read from source into buffer which is resized to the number of bytes read on eof.
