    • Method Detail

      • buildPreferredDisplaySequence

        protected void buildPreferredDisplaySequence()

        Use the default encoded order.

      • findLead

        protected static int findLead​(java.lang.String[] leadNames,
                              java.lang.String leadName)

        Find the named lead in an array of lead names.

        Parameters:
        leadNames - an array of String names to designate leads (may be null, or contain null strings, in which case won't be found)
        leadName - the string name of the lead wanted (may be null, in which case won't be found)
        Returns:
        the index in leadNames of the requested lead if present, else -1

      • buildPreferredDisplaySequence

        protected void buildPreferredDisplaySequence​(java.lang.String[] labels)

        Using the lead descriptions, look for patterns and determine the desired sequential display order, defaulting to the encoded order if no recognized pattern.

        Parameters:
        labels - the labels to use to match the preferred order (may or may not be this.channelNames)
