Package com.cedarsoftware.util

Class CompactLinkedMap<K,V>

java.lang.Object

com.cedarsoftware.util.CompactMap<K,V>

com.cedarsoftware.util.CompactLinkedMap<K,V>

Type Parameters:

K - the type of keys maintained by this map

V - the type of mapped values

All Implemented Interfaces:

Map<K,V>

public class CompactLinkedMap<K,V>
extends CompactMap<K,V>

A case-insensitive Map implementation that uses a compact internal representation for small maps. This Map exists to simplify JSON serialization. No custom reader nor writer is needed to serialize this map. It is a drop-in replacement for LinkedHashMap.

Method Details

getNewMap

protected Map<K,V> getNewMap()

Description copied from class: CompactMap

Creates the backing map instance when size exceeds compactSize.

Default implementation returns HashMap. Override to provide different map implementation (e.g., TreeMap for sorted maps, LinkedHashMap for insertion ordered maps).

Overrides:

getNewMap in class CompactMap<K,V>

Returns:

new empty map instance for backing storage

isCaseInsensitive

protected boolean isCaseInsensitive()

Description copied from class: CompactMap

Determines if String keys are compared case-insensitively.

Default implementation returns false (case-sensitive). Override to change String key comparison behavior. Affects key equality and sorting.

Overrides:

isCaseInsensitive in class CompactMap<K,V>

Returns:

true if String keys should be compared ignoring case, false otherwise

useCopyIterator

protected boolean useCopyIterator()
