splitSRID

public static String[] splitSRID(String whole)
                          throws SQLException

Splits a String at the first occurrence of border character. Poor man's String.split() replacement, as String.split() was invented at jdk1.4, and the Debian PostGIS Maintainer had problems building the woody backport of his package using DFSG-free compilers. In all the cases we used split() in the net.postgis package, we only needed to split at the first occurence, and thus this code could even be faster.

Parameters:

whole - the String to be split

Returns:

String array containing the split elements

Throws:

SQLException - when a SQLException occurrs
