isEmpty() method on the property). This is
useful because the SDK will never return a null collection or map, but you may need to differentiate between the
service returning nothing (or null) and the service returning an empty collection or map. For requests, this
returns true if a value for the property was specified in the request builder, and false if a value was not
specified.public final List<ColumnDefinition> columns()
List of column definitions.
Attempts to modify the collection returned by this method will result in an UnsupportedOperationException.
This method will never return null. If you would like to know whether the service returned this field (so that
you can differentiate between null and empty), you can use the hasColumns() method.
