Record Class DistributedMapConfig

java.lang.Object

java.lang.Record

com.loomcache.server.datastructures.DistributedMapConfig

public record DistributedMapConfig(int maxSize, DistributedMapConfig.EvictionPolicy evictionPolicy, boolean metricsEnabled, long maxIdleMillis)
extends Record

Per-map configuration for a DistributedMap instance.

Uses a builder so operators can tune per-map behavior before deployment:

var config = DistributedMapConfig.builder()
    .maxSize(10_000)
    .evictionPolicy(EvictionPolicy.LRU)
    .build();
var map = new DistributedMap<>("sessions", 1, config);

Immutable after construction — safe to share across threads.

Field Details

DEFAULT

public static final DistributedMapConfig DEFAULT

Default config: unbounded, no eviction, metrics enabled, no max-idle expiry.

Constructor Details

DistributedMapConfig

public DistributedMapConfig(int maxSize,
 DistributedMapConfig.EvictionPolicy evictionPolicy,
 boolean metricsEnabled,
 long maxIdleMillis)

Creates an instance of a DistributedMapConfig record class.

Parameters:

maxSize - the value for the maxSize record component

evictionPolicy - the value for the evictionPolicy record component

metricsEnabled - the value for the metricsEnabled record component

maxIdleMillis - the value for the maxIdleMillis record component

DistributedMapConfig

public DistributedMapConfig(int maxSize,
 DistributedMapConfig.EvictionPolicy evictionPolicy,
 boolean metricsEnabled)

Method Details

hasSizeLimit

public boolean hasSizeLimit()

True if this config enforces a size limit.

hasMaxIdle

public boolean hasMaxIdle()

True if this config expires entries that have not been accessed recently.

builder

public static DistributedMapConfig.Builder builder()

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. Reference components are compared with Objects::equals(Object,Object); primitive components 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.

maxSize

public int maxSize()

Returns the value of the maxSize record component.

Returns:

the value of the maxSize record component

evictionPolicy

public DistributedMapConfig.EvictionPolicy evictionPolicy()

Returns the value of the evictionPolicy record component.

Returns:

the value of the evictionPolicy record component

metricsEnabled

public boolean metricsEnabled()

Returns the value of the metricsEnabled record component.

Returns:

the value of the metricsEnabled record component

maxIdleMillis

public long maxIdleMillis()

Returns the value of the maxIdleMillis record component.

Returns:

the value of the maxIdleMillis record component
