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.

toString() → String

A string representation of this object.

Operators

operator ==(Object other) → bool

The equality operator.
