Class ArrayValueMap

java.lang.Object
  com.google.api.client.util.ArrayValueMap

public final class ArrayValueMap
extends Object

Collects the array values of a key/value data object, writing the fields or map values only after all values have been collected.

The typical application for this is when parsing JSON or XML when the value type is known to be an array. It stores the values in a collection during the parsing, and only when the parsing of an object is finished does it convert the collection into an array and stores it.

Use put(String, Class, Object) when the destination object is a map with string keys and whose values accept an array of objects. Use put(Field, Class, Object) when setting the value of a field using reflection, assuming its type accepts an array of objects. One can potentially use both put methods for example on an instance of GenericData.

Implementation is not thread-safe. For a thread-safe choice instead use an implementation of ConcurrentMap.
