Method Details

lifespan

public long lifespan()

Description copied from interface: Metadata

Returns the lifespan of the cache entry with which this metadata object is associated, in milliseconds. Negative values are interpreted as unlimited lifespan.

Specified by:

lifespan in interface Metadata

Returns:

lifespan of the entry in number of milliseconds

maxIdle

public long maxIdle()

Description copied from interface: Metadata

Returns the the maximum amount of time that the cache entry associated with this metadata object is allowed to be idle for before it is considered as expired, in milliseconds.

Specified by:

maxIdle in interface Metadata

Returns:

maximum idle time of the entry in number of milliseconds

version

public EntryVersion version()

Description copied from interface: Metadata

Returns the version of the cache entry with which this metadata object is associated.

Specified by:

version in interface Metadata

Returns:

version of the entry

getNumericVersion

@ProtoField(1)
public NumericVersion getNumericVersion()

getClusteredVersion

@ProtoField(2)
public SimpleClusteredVersion getClusteredVersion()

isEmpty

public boolean isEmpty()

Description copied from interface: Metadata

Returns whether this metadata is effectively empty, that is that persisting or replicating it to another node would be no different then sending a null metadata object.

Specified by:

isEmpty in interface Metadata

Returns:

if this metadata has no actual data to store

builder

public Metadata.Builder builder()

Description copied from interface: Metadata

Returns an instance of Metadata.Builder which can be used to build new instances of Metadata instance which are full copies of this Metadata.

Specified by:

builder in interface Metadata

Returns:

instance of Metadata.Builder
