Usage

From source file:com.pongasoft.kiwidoc.builder.doclet.SourceCodeParser.java

/**
 * Parses the sources using a doclet. It is ok to provide a big number of files, since it will
 * automatically be split in chunks./*from   w  w  w  . j  a  v  a  2  s .  c  om*/
 *
 * @param library the library to store the results
 * @param sources the sources
 * @return the number of processed files
 * @throws IOException if there is an issue reading the files
