Class CompactCIHashMap<K,V>

java.lang.Object
com.cedarsoftware.util.CompactMap<K,V>
com.cedarsoftware.util.CompactCIHashMap<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 CompactCIHashMap<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 HashMap if you want case-insensitive behavior for String keys and compactness. This creates a CompactMap with:
  • compactSize = 40 (same as CompactCIHashMap)
  • caseSensitive = false (case-insensitive behavior)
  • ordering = UNORDERED (standard HashMap behavior)

  • 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()
