Class PrivateMaxEntriesMap.Builder<K,V>

java.lang.Object

com.fasterxml.jackson.databind.util.internal.PrivateMaxEntriesMap.Builder<K,V>

Enclosing class:

PrivateMaxEntriesMap<K,V>

public static final class PrivateMaxEntriesMap.Builder<K,V>
extends Object

A builder that creates PrivateMaxEntriesMap instances. It provides a flexible approach for constructing customized instances with a named parameter syntax. It can be used in the following manner:

 ConcurrentMap<Vertex, Set<Edge>> graph = new Builder<Vertex, Set<Edge>>()
     .maximumCapacity(5000)
     .build();

Method Detail

initialCapacity

public PrivateMaxEntriesMap.Builder<K,V> initialCapacity(int initialCapacity)

Specifies the initial capacity of the hash table (default 16). This is the number of key-value pairs that the hash table can hold before a resize operation is required.

Parameters:

initialCapacity - the initial capacity used to size the hash table to accommodate this many entries.

Throws:

IllegalArgumentException - if the initialCapacity is negative

maximumCapacity

public PrivateMaxEntriesMap.Builder<K,V> maximumCapacity(long capacity)

Specifies the maximum capacity to coerce the map to and may exceed it temporarily.

Parameters:

capacity - the threshold to bound the map by

Throws:

IllegalArgumentException - if the maximumCapacity is negative

concurrencyLevel

public PrivateMaxEntriesMap.Builder<K,V> concurrencyLevel(int concurrencyLevel)

Specifies the estimated number of concurrently updating threads. The implementation performs internal sizing to try to accommodate this many threads (default 16).

Parameters:

concurrencyLevel - the estimated number of concurrently updating threads

Throws:

IllegalArgumentException - if the concurrencyLevel is less than or equal to zero

listener

public PrivateMaxEntriesMap.Builder<K,V> listener(com.fasterxml.jackson.databind.util.internal.EvictionListener<K,V> listener)

Specifies an optional listener that is registered for notification when an entry is evicted.

Parameters:

listener - the object to forward evicted entries to

Throws:

NullPointerException - if the listener is null

build

public PrivateMaxEntriesMap<K,V> build()

Creates a new PrivateMaxEntriesMap instance.

Throws:

IllegalStateException - if the maximum capacity was not set
