Class PropertySetCache

java.lang.Object

com.atlassian.jira.propertyset.PropertySetCache

public class PropertySetCache
extends Object

This class provides a cache for PropertySet values as used by JiraCachingPropertySet.

The intention is that the cache is non-blocking for reads, and it is up to the JiraCachingPropertySet to synchronise writes with reading/writing from the underlying Property Set.

This cache looks and works a lot like a PropertySet for obvious reasons, however it is not declared to implement PropertySet because it does not implement all methods - only the ones we want to cache for. With that in mind, it generally attempts to follow the contract of the PropertySet interface. Namely:

• If a property is retrieved that exists but contains a value of different type, a InvalidPropertyTypeException should be thrown.
• If a property is retrieved that does not exist, null (or the primitive equivalent) is returned.

Since:

v4.0

public void remove(String key)

clear

public void clear()

bulkLoad

public void bulkLoad(com.opensymphony.module.propertyset.PropertySet source)

Eagerly loads all the values from the given PropertySet into this cache.

Parameters:

source - The PropertySet to bulk load from.

exists

public Boolean exists(String key)

Returns the cached value for whether the given key exists in the underlying PropertySet.

It is important not to confuse this method with the Map.containsKey(java.lang.Object) method.

Parameters:

key - The property key.

Returns:

A Boolean object containing the cached existance of a value for the key, or null if we haven't cached the existance for this key.
