public class Indexer
extends BinaryExpression
implements org.jvnet.jaxb2_commons.lang.Equals2, org.jvnet.jaxb2_commons.lang.HashCode2, org.jvnet.jaxb2_commons.lang.ToString2

The Indexer operator returns the indexth element in a string or list. Indexes in strings and lists are defined to be 0-based. If the index is less than 0 or greater than the length of the string or list being indexed, the result is null. If either argument is null, the result is null.
