Detailed Description

parser for the STAR file format

STAR format description

In essence, STAR files are structured text files. A few simple control structures control the interpretation of the content.

Commented lines start with a '#'.
a data section starts with data_<id> and ends, whenever another data block starts or at the end of the file.
data-items consist of a name-value pair. Names start with an underscore and are made up of a category and an identifier. The category and the identifier are separated by a '.'. The name is followed by a simple or quoted value.
lists of data items are specified using the loop_ keyword, followed by a list of column names and values.

create a StarParser

Parameters:

stream	input stream
item_as_row	if true, data-items are first gathered (identifier as header, values as row) and then parsed like a loop (OnBeginLoop(), OnDataRow(), OnEndLoop())
