Detailed Description

The Writer class is initialized with a stream to which to write a version 1.0 or 3.0 Les Houches Accord event file. In the init() function of the Writer object the main XML tag, header and init blocks are written, with the corresponding end tag is written by list_end_tag(). After a Writer object (in the following called "writer") has been created, it is possible to assign version (3 by default) information by

writer.version =

;

The header block (called "someHeaderString" below) is assigned by

writer.headerBlock() << someHeaderString;

and the init block comments (called "someInitString" below) are assigned via

writer.initComments() << someInitString;

The standard init information (including amendments for LHEF 3.0) can be assigned by the heprup member variable:

writer.heprup = heprup;

where heprup is an object of type HEPRUP. All of the above information will be writen by calling the init() function.

Before each event is written out with the writeEvent() function, the standard event information can be assigned to the hepeup variable by

writer.hepeup = hepeup;

where hepeup is of type HEPEUP. Event comments (called "someCommentString" below) can be assigned through

writer.eventComments() << someCommentString;

All of this event information is written by the writeEvent() function.
