io microsphere spring config env ImmutableMapPropertySource

ImmutableMapPropertySource

Type: Class | Module: microsphere-spring-context | Package: io.microsphere.spring.config.env | Since: 1.0.0

Source: microsphere-spring-context/src/main/java/io/microsphere/spring/config/env/ImmutableMapPropertySource.java

Overview

An immutable implementation of MapPropertySource that ensures the underlying map remains unmodifiable.

This class is useful in scenarios where the configuration properties should be protected from further modifications after initialization. It wraps the provided source map into an unmodifiable map using java.util.Collections#unmodifiableMap(Map).

Example Usage

`Map source = new HashMap<>();
    source.put("key1", "value1");
    source.put("key2", 42);

    ImmutableMapPropertySource propertySource = new ImmutableMapPropertySource("mySource", source);

    // The following operations will throw UnsupportedOperationException
    try {
        propertySource.getPropertySources().addLast(new CustomPropertySource());
    ` catch (UnsupportedOperationException e) {
        // Expected exception
    }
}

Declaration

public class ImmutableMapPropertySource extends MapPropertySource
