Class CachingTypedPropertyMap<T>

java.lang.Object

com.foreach.common.spring.properties.TypedPropertyMap<T>

com.foreach.common.spring.properties.CachingTypedPropertyMap<T>

All Implemented Interfaces:

Cloneable, Map<T,Object>

public class CachingTypedPropertyMap<T>
extends TypedPropertyMap<T>

Extends the TypedPropertyMap by caching the values instead of converting all the time. Changes directly in the source map will not be detected unless an explicit refresh() is done. Changes through the CachingTypedPropertyMap should not be a problem.

Note: Only call for the registered type will be cached, that means that direct calls to TypedPropertyMap.getValue(Object, Class) will always use the conversionService.

Constructor Detail

CachingTypedPropertyMap

public CachingTypedPropertyMap(PropertyTypeRegistry<T> propertyTypeRegistry,
                               Map<T,?> source,
                               Class sourceValueClass)

Method Detail

getValue

public <O> O getValue(T property)

Description copied from class: TypedPropertyMap

Allows a strong typed property to be fetched from the source map. This method will lookup the specific type of the property requested. Use the conversionService to convert the source value to the typed value, and then case the result to the type requested.

Overrides:

getValue in class TypedPropertyMap<T>

Type Parameters:

O - Strong type value to return, the must registered type for the property must be able to cast to this type!

Parameters:

property - Key of the property.

Returns:

Strong typed instance of the property.

set

public Object set(T property,
                  Object value)

Description copied from class: TypedPropertyMap

Stores the property value in the source map by converting it to the sourceValueClass first.

Overrides:

set in class TypedPropertyMap<T>

Parameters:

property - Key of the property.

value - Strong type value to set the property to.

clear

public void clear()

Specified by:

clear in interface Map<T,Object>

Overrides:

clear in class TypedPropertyMap<T>

remove

public Object remove(Object key)

Specified by:

remove in interface Map<T,Object>

Overrides:

remove in class TypedPropertyMap<T>

refresh

public void refresh()

Clears all cached values, ensuring that on the next request the properties will be converted again.

detach

public TypedPropertyMap<T> detach()

Creates a duplicate of the TypedPropertyMap with its own property source, but the same registry and conversionService.

Overrides:

detach in class TypedPropertyMap<T>

Returns:

Detached duplicate of the current map.
