Usage

From source file:jofc2.OFC.java

/**
 * Convenience method for converting Collections to Arrays. You can use this
 * where the API has limited support for collections:
 * getLabels().addLabels(OFC.toArray(stringList, String.class));
 * //from  ww  w  . ja va  2s . co m
 * @param collection
 *            The collection to use
 * @param type
 *            The supertype for the collection. This will commonly be
 *            Integer, Number, etc.
 * @return the array of the collection
