public class JSONGetAllFunction
extends cascading.nested.core.NestedGetAllFunction<JsonNode,ArrayNode>

Class JSONGetAllFunction provides the ability to retrieve a list of child nodes and convert each JSON object into tuple of values. Note the stringRootPointer may reference a JSON Array, /person/*, or it may be a pointer-path descent reference, /person/**/name. In the later case, use an empty pointer, "", to reference the value of the array. Rely on the fieldDeclaration to coerce this value appropriately.
