Class JsonMap

java.lang.Object

java.util.AbstractMap<K,V>

com.tangosol.util.LiteMap<String,Object>

com.tangosol.coherence.rest.util.JsonMap

All Implemented Interfaces:

ExternalizableLite, Versionable<Integer>, Externalizable, Serializable, Cloneable, Map<String,Object>

public class JsonMap
extends LiteMap<String,Object>
implements Versionable<Integer>

A simple wrapper around LiteMap that preserves the order of elements and adds support for POF serialization without fidelity loss in order to support JSON pass-through.

Constructor Detail

JsonMap

public JsonMap()

Construct a JsonMap.

JsonMap

public JsonMap(Map<? extends String,?> map)

Construct a JsonMap with the same mappings as the given map.

Parameters:

map - the map whose mappings are to be placed in this map.

Method Detail

instantiateMap

protected Map<String,Object> instantiateMap()

Description copied from class: LiteMap

(Factory pattern) Instantiate a Map object to store entries in once the "lite" threshold has been exceeded. This method permits inheriting classes to easily override the choice of the Map object.

Overrides:

instantiateMap in class LiteMap<String,Object>

Returns:

an instance of Map

getVersionIndicator

public Integer getVersionIndicator()

Description copied from interface: Versionable

Get the version indicator for this object. The version indicator should be an immutable object or one treated as an immutable, which is to say that after the version is incremented, the previous version's indicator reference will never be returned again.

Specified by:

getVersionIndicator in interface Versionable<Integer>

Returns:

a non-null version value that implements the Comparable interface

incrementVersion

public void incrementVersion()

Description copied from interface: Versionable

Update the version to the next logical version indicator.

Specified by:

incrementVersion in interface Versionable<Integer>
