io microsphere collection ImmutableEntry

ImmutableEntry

Type: Class | Module: microsphere-java-core | Package: io.microsphere.collection

Source: microsphere-java-core/src/main/java/io/microsphere/collection/ImmutableEntry.java

Overview

An immutable implementation of Map.Entry that stores a fixed key-value pair.

This class provides a read-only entry suitable for use in immutable maps. Once created, the key and value cannot be changed, and calling #setValue(Object) will throw an UnsupportedOperationException.

Example Usage

`ImmutableEntry entry = ImmutableEntry.of("age", 30);
System.out.println(entry.getKey());   // Output: age
System.out.println(entry.getValue()); // Output: 30

// The following line would throw an exception:
// entry.setValue(25); // throws UnsupportedOperationException
`

Declaration

public class ImmutableEntry<K, V> extends DefaultEntry<K, V>
