Class ChainedDynamicProperty

java.lang.Object
  com.netflix.config.ChainedDynamicProperty

public class ChainedDynamicProperty
extends java.lang.Object

The class that provides the chaining functionality of dynamic properties. The idea is that the head property holds the current up-to-date value of the property and the "next" property in the chain serves as the default if the head property value does not exist or is not acceptable. Concrete implementation is available for IntProperty, StringProperty, BooleanProperty and FloatProperty.

For example

  DynamicStringProperty pString = DynamicPropertyFactory.getInstance().getStringProperty("defaultString", "default-default");
        ChainedDynamicProperty.StringProperty fString = new ChainedDynamicProperty.StringProperty("overrideString", pString);

        assertTrue("default-default".equals(fString.get()));

        ConfigurationManager.getConfigInstance().setProperty("defaultString", "default");
        assertTrue("default".equals(fString.get()));

        ConfigurationManager.getConfigInstance().setProperty("overrideString", "override");
        assertTrue("override".equals(fString.get()));

        ConfigurationManager.getConfigInstance().clearProperty("overrideString");
        assertTrue("default".equals(fString.get()));

        ConfigurationManager.getConfigInstance().clearProperty("defaultString");
        assertTrue("default-default".equals(fString.get()));
