FifoEvictionPolicy class

Using this algorithm the cache behaves in the same way as a FIFO queue. The cache evicts the sampled entries in the order they were added, without any regard to how often or how many times they were accessed before. This algorithm uses CacheInfo.creationTime to keep track of when a entry was created.

Properties

hashCode → int

The hash code for this object.

no setter, inherited

runtimeType → Type

A representation of the runtime type of the object.

Methods

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

select(Iterable<CacheInfo?> entries, DateTime now) → CacheInfo?

Finds the best eviction candidate based on the sampled entries. What distinguishes this approach from the classic data structures approach is that an CacheInfo contains metadata (e.g. usage information) which can be used for making policy decisions, while generic data structures do not. It is expected that implementations will take advantage of that metadata.

inherited

selectEntry(CacheInfo entry, CacheInfo selectedEntry, DateTime now) → bool

Returns true if entry is a better candidate for eviction than the current selectedEntry

toString() → String

A string representation of this object.

Operators

operator ==(Object other) → bool

The equality operator.
