Detailed Description

Container of strings that represents a line in a SLHA structure. This class is a container of strings that represents a line in a SLHA structure. The elements of a Line are the so called fields of an ordinary SLHA line, which are its whitespace-separated substrings and the comment. For example, if a Line is constructed from the string " 1 2 0.123 # a comment" its elements would be "1", "2", "0.123", and "# a comment". Array-style access to the elements with integer indices is provided by the operator[]() and at() functions. Line also provides introspective functions to find out whether it is a comment or data line for example. Introspective functions that check if an element is a block specifier ("BLOCK" or "DECAY") always perform case-insensitive comparisons.

In addition to storing the fields of a SLHA line, a Line also stores its formatting (the exact position of the fields in the line). A formatted representation of a Line can be produced with str() const. The reformat() function clears the previous formatting and indents all elements with an appropriate number of spaces.
