Usage

From source file:org.comixwall.pffw.GraphsBase.java

/**
 * Run the controller task.//from  w  w  w . j av a 2 s  .  c  o m
 * We fetch the graphs using secure http, or fall back to plain http if secure connection fails.
 * <p>
 * Note that the PFFW uses a self-signed server certificate. So the code should trust that certificate
 * and not reject the hostname.
 *
 * @return True on success, false on failure.
