Class CompactMap.CompactMapComparator

java.lang.Object

com.cedarsoftware.util.CompactMap.CompactMapComparator

All Implemented Interfaces:

Comparator<Object>

Enclosing class:

CompactMap<K,V>

public static class CompactMap.CompactMapComparator
extends Object
implements Comparator<Object>

Comparator implementation for CompactMap key ordering.

Provides comparison logic that:

• Handles case sensitivity for String keys
• Supports natural or reverse ordering
• Maintains consistent ordering for different key types
• Properly handles null keys (always last)

Used by sorted CompactMaps and during compact array sorting.

Method Details

get

public static CompactMap.CompactMapComparator get(boolean caseInsensitive,
 boolean reverse)

Returns a cached comparator instance for the specified configuration. Since there are only 4 possible combinations, all instances are pre-created.

Parameters:

caseInsensitive - true for case-insensitive String comparison

reverse - true for reverse ordering

Returns:

a cached CompactMapComparator instance

compare

public int compare(Object key1,
 Object key2)

Specified by:

compare in interface Comparator<Object>

toString

public String toString()

Overrides:

toString in class Object
