SizedConcurrentHashMap (OpenJPA Parent POM 2.4.0 API)

java.lang.Object
- java.util.AbstractMap<K,V>
- - java.util.concurrent.ConcurrentHashMap
  - - org.apache.openjpa.lib.util.concurrent.NullSafeConcurrentHashMap
    - - org.apache.openjpa.lib.util.concurrent.SizedConcurrentHashMap

All Implemented Interfaces:

Serializable, ConcurrentMap, Map, SizedMap

Deprecated.
In Java 8, java.util.ConcurrentHashMap received an overhauled and this extension was not updated. This class will fail to compile on Java 8. If it is compiled at a lower level and run on Java 8 it will not work properly. For more information: https://issues.apache.org/jira/browse/OPENJPA-2441
```
@Deprecated
public class SizedConcurrentHashMap
extends NullSafeConcurrentHashMap
implements SizedMap, ConcurrentMap, Serializable
```
An implementation of SizedMap that uses JDK1.5 concurrency primitives

Since:

1.1.0

Modifier and Type	Method and Description
`int`	`getMaxSize()` Deprecated. The maximum number of entries, or Integer.MAX_VALUE for no limit.
`boolean`	`isFull()` Deprecated. Whether the map is full.

public SizedConcurrentHashMap(int size,
                      float load,
                      int concurrencyLevel)
```
    Deprecated.
    
    Parameters:
    size - the maximum size of this map. If additional elements are put into the map, overflow will be removed via calls to overflowRemoved(java.lang.Object, java.lang.Object).
    load - the load factor for the underlying map
    concurrencyLevel - the concurrency level for the underlying map

  - setMaxSize
```
public void setMaxSize(int max)
