Method Detail

create

InternalCacheEntry create(CacheEntry cacheEntry)

Creates a new InternalCacheEntry instance based on the key, value, version and timestamp/lifespan information reflected in the CacheEntry instance passed in.

Parameters:

cacheEntry - cache entry to copy

Returns:

a new InternalCacheEntry

create

InternalCacheEntry create(Object key,
                          Object value,
                          InternalCacheEntry cacheEntry)

Creates a new InternalCacheEntry instance based on the version and timestamp/lifespan information reflected in the CacheEntry instance passed in. Key and value are both passed in explicitly.

Parameters:

key - key to use

value - value to use

cacheEntry - cache entry to retrieve version and timestamp/lifespan information from

Returns:

a new InternalCacheEntry

create

InternalCacheEntry create(Object key,
                          Object value,
                          EntryVersion version)

Creates a new InternalCacheEntry instance

Parameters:

key - key to use

value - value to use

version - version to use

Returns:

a new InternalCacheEntry

create

InternalCacheEntry create(Object key,
                          Object value,
                          EntryVersion version,
                          long lifespan,
                          long maxIdle)

Creates a new InternalCacheEntry instance

Parameters:

key - key to use

value - value to use

version - version to use

lifespan - lifespan to use

maxIdle - maxIdle to use

Returns:

a new InternalCacheEntry

create

InternalCacheEntry create(Object key,
                          Object value,
                          EntryVersion version,
                          long created,
                          long lifespan,
                          long lastUsed,
                          long maxIdle)

Creates a new InternalCacheEntry instance

Parameters:

key - key to use

value - value to use

version - version to use

created - creation timestamp to use

lifespan - lifespan to use

lastUsed - lastUsed timestamp to use

maxIdle - maxIdle to use

Returns:

a new InternalCacheEntry

update

InternalCacheEntry update(InternalCacheEntry cacheEntry,
                          long lifespan,
                          long maxIdle)

Updates an existing InternalCacheEntry with new lifespan and maxIdle values. This may result in a new InternalCacheEntry instance being created, as a different InternalCacheEntry implementation may be more appropriate to suit the new lifespan and maxIdle values. As such, one should consider the InternalCacheEntry passed in as a parameter as passed by value and not by reference.

Parameters:

cacheEntry - original internal cache entry

lifespan - new lifespan to use

maxIdle - new maxIdle to use

Returns:

a new InternalCacheEntry instance

createValue

InternalCacheValue createValue(CacheEntry cacheEntry)

Creates an InternalCacheValue based on the InternalCacheEntry passed in.

Parameters:

cacheEntry - to use to generate a InternalCacheValue

Returns:

an InternalCacheValue
