Class Exporter.NullConcurrentHashMap

java.lang.Object

java.util.AbstractMap<K,V>

java.util.concurrent.ConcurrentHashMap<String,Resource[]>

org.universAAL.ri.gateway.Exporter.NullConcurrentHashMap

All Implemented Interfaces:

Serializable, ConcurrentMap<String,Resource[]>, Map<String,Resource[]>

Enclosing class:

Exporter

public static class Exporter.NullConcurrentHashMap
extends ConcurrentHashMap<String,Resource[]>

Helper class that wraps ConcurrentHashMap allowing for null values. Null values are internally converted to/from a token constant. Use getNullable and putNullable instead of the original get and put. It was done this way because get and put are used internally and should not be overridden.
