Method Detail

getMetadata

public Metadata getMetadata()

Description copied from interface: MetadataAware

Get metadata of this cache entry.

Specified by:

getMetadata in interface MetadataAware

Overrides:

getMetadata in class ImmortalCacheEntry

Returns:

a Metadata instance

setMetadata

public void setMetadata(Metadata metadata)

Description copied from interface: MetadataAware

Set the metadata in the cache entry.

Specified by:

setMetadata in interface MetadataAware

Overrides:

setMetadata in class ImmortalCacheEntry

Parameters:

metadata - to apply to the cache entry

toInternalCacheValue

public InternalCacheValue<?> toInternalCacheValue()

Description copied from interface: InternalCacheEntry

Creates a representation of this entry as an InternalCacheValue. The main purpose of this is to provide a representation that does not have a reference to the key. This is useful in situations where the key is already known or stored elsewhere, making serialization and deserialization more efficient.

Note that this should not be used to optimize memory overhead, since the saving of an additional reference to a key (a single object reference) does not warrant the cost of constructing an InternalCacheValue. This only makes sense when marshalling is involved, since the cost of marshalling the key again can be sidestepped using an InternalCacheValue if the key is already known/marshalled.

Specified by:

toInternalCacheValue in interface InternalCacheEntry

Overrides:

toInternalCacheValue in class ImmortalCacheEntry

Returns:

a new InternalCacheValue encapsulating this InternalCacheEntry's value and expiration information.

appendFieldsToString

protected void appendFieldsToString(StringBuilder builder)

Overrides:

appendFieldsToString in class AbstractInternalCacheEntry
