Constructor Detail

KeyValueFileParser

public KeyValueFileParser(Class<Key> enumType)

Simple constructor.

Parameters:

enumType - type of the parameters keys enumerate

Method Detail

parseInput

public void parseInput(String name,
                       InputStream input)
                throws IOException

Parse an input file.

The input file syntax is a set of key=value lines or key[i]=value lines. Blank lines and lines starting with '#' (after whitespace trimming) are silently ignored. The equal sign may be surrounded by space characters. Keys must correspond to the Key enumerate constants, given that matching is not case sensitive and that '_' characters may appear as '.' characters in the file. This means that the lines:

   # this is the semi-major axis
   orbit.circular.a   = 7231582
 

are perfectly right and correspond to key Key#ORBIT_CIRCULAR_A if such a constant exists in the enumerate.

When the key[i] notation is used, all the values extracted from lines with the same key will be put in a general array that will be retrieved using one of the getXxxArray(key) methods. They will not be available with the getXxx(key) methods without the Array.

Parameters:

name - input file name

input - input stream

Throws:

IOException - if input file cannot be read
