Method Detail

expiresAt

public int expiresAt(CacheConfig config)

Description copied from class: AbstractStatelessTimestampedValue

Get the time at which this timestamp will become invalid. If the config specified ttl == tti == 0, making items eternal, then this method returns TimestampedValue.NEVER_EXPIRE.

Specified by:

expiresAt in interface TimestampedValue<byte[]>

Overrides:

expiresAt in class AbstractStatelessTimestampedValue<byte[]>

Parameters:

config - The configuration

Returns:

Timestamp of expiration, >0, may be NEVER_EXPIRE if eternal
