Interface EntityPropertyCache

All Superinterfaces
  Serializable

    public interface EntityPropertyCache

extends Serializable

Class used to hold properties for a given entity. An instance of this class is used as the runtime store for a ConfigurableEntity EJB during its lifecycle, as a container to pass properties from the EntityPropertyManager to an entity, and as a container to cache properties in the application-wide cache by the EntityPropertyManager.

`Object` | `get(PropertyMapKey key)` Get a value from the cache
`List` | `getContentsAsString()` Describes the contents of this cache as a List of Strings such as: {"propertySet:propertyName=propertyValue" }
`Iterator` | `getEntries()`
`Map` | `getMap()` Get the entire map that backs up the cache
`boolean` | `isEmpty()`
`void` | `put(PropertyMapKey key, Object value)` Put a value in the cache
`void` | `putAll(Map map)` Add all the key/value pairs from the given map to the cache
`void` | `remove(PropertyMapKey key)` Remove a value from the cache
`int` | `size()`

    the property value, or null if there is none.

### remove

    void remove(PropertyMapKey key)

  Remove a value from the cache

  Parameters
    `key` - the key to remove

### put

    void put(PropertyMapKey key,
             Object value)

  Parameters
    `map` - the Map containing values to add

### getMap

  Returns
    an Iterator over the cache entry set. Will return null for an empty cache.

### clear

    void clear()

  Clear the cache

### getContentsAsString
