Record Class LoomMap.LoomMapStats

java.lang.Object

java.lang.Record

com.loomcache.client.LoomMap.LoomMapStats

Record Components:

localCacheHits - number of operations satisfied without a remote round-trip

remoteFetches - number of operations that issued a remote request

totalOps - total number of operations performed

avgLatencyMs - average operation latency in milliseconds

Enclosing class:

LoomMap<K,V>

public static record LoomMap.LoomMapStats(long localCacheHits, long remoteFetches, long totalOps, double avgLatencyMs)
extends Record

Statistics snapshot for a LoomMap operation.

localCacheHits reflects the fraction of operations whose result was served without hitting the wire — i.e. totalOps - remoteFetches. Every LoomMap call that reaches the client goes through the shared LoomClient, which handles its own near cache; LoomMap itself only measures the work it dispatches, so in the absence of richer bookkeeping every recorded operation is counted as a remote fetch and localCacheHits stays at zero.

Constructor Details

LoomMapStats

public LoomMapStats(long localCacheHits,
 long remoteFetches,
 long totalOps,
 double avgLatencyMs)

Creates an instance of a LoomMapStats record class.

Parameters:

localCacheHits - the value for the localCacheHits record component

remoteFetches - the value for the remoteFetches record component

totalOps - the value for the totalOps record component

avgLatencyMs - the value for the avgLatencyMs record component

Method Details

hitRatePercent

public double hitRatePercent()

Returns the local cache hit rate as a percentage (0.0 to 100.0).

toString

public final String toString()

Returns a string representation of this record class. The representation contains the name of the class, followed by the name and value of each of the record components.

Specified by:

toString in class Record

Returns:

a string representation of this object

hashCode

public final int hashCode()

Returns a hash code value for this object. The value is derived from the hash code of each of the record components.

Specified by:

hashCode in class Record

Returns:

a hash code value for this object

equals

public final boolean equals(Object o)

Indicates whether some other object is "equal to" this one. The objects are equal if the other object is of the same class and if all the record components are equal. All components in this record class are compared with the compare method from their corresponding wrapper classes.

Specified by:

equals in class Record

Parameters:

o - the object with which to compare

Returns:

true if this object is the same as the o argument; false otherwise.

localCacheHits

public long localCacheHits()

Returns the value of the localCacheHits record component.

Returns:

the value of the localCacheHits record component

remoteFetches

public long remoteFetches()

Returns the value of the remoteFetches record component.

Returns:

the value of the remoteFetches record component

totalOps

public long totalOps()

Returns the value of the totalOps record component.

Returns:

the value of the totalOps record component

avgLatencyMs

public double avgLatencyMs()

Returns the value of the avgLatencyMs record component.

Returns:

the value of the avgLatencyMs record component
