Method Detail

buildPreferredDisplaySequence

protected void buildPreferredDisplaySequence()

Use the default encoded order.

findLead

protected static int findLead(String[] leadNames,
                              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(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)
