Examples with SettingUpdater org.elasticsearch.common.settings.AbstractScopedSettings.SettingUpdater used on opensource projects

Example 1 with SettingUpdater

use of org.elasticsearch.common.settings.AbstractScopedSettings.SettingUpdater in project crate by crate.

the class SettingTests method testAffixMapUpdateWithNullSettingValue.

@Test
public void testAffixMapUpdateWithNullSettingValue() {
    // GIVEN an affix setting changed from "prefix._foo"="bar" to "prefix._foo"=null
    final Settings current = Settings.builder().put("prefix._foo", (String) null).build();
    final Settings previous = Settings.builder().put("prefix._foo", "bar").build();
    final Setting.AffixSetting<String> affixSetting = Setting.prefixKeySetting("prefix" + ".", key -> Setting.simpleString(key, Property.Dynamic, Property.NodeScope));
    final Consumer<Map<String, String>> consumer = (map) -> {
    };
    final BiConsumer<String, String> validator = (s1, s2) -> {
    };
    // WHEN creating an affix updater
    final SettingUpdater<Map<String, String>> updater = affixSetting.newAffixMapUpdater(consumer, logger, validator);
    // THEN affix updater is always expected to have changed (even when defaults are omitted)
    assertTrue(updater.hasChanged(current, previous));
    // THEN changes are expected when defaults aren't omitted
    final Map<String, String> updatedSettings = updater.getValue(current, previous);
    assertNotNull(updatedSettings);
    assertEquals(1, updatedSettings.size());
    // THEN changes are reported when defaults aren't omitted
    final String key = updatedSettings.keySet().iterator().next();
    final String value = updatedSettings.get(key);
    assertEquals("_foo", key);
    assertEquals("", value);
}

Example 2 with SettingUpdater

use of org.elasticsearch.common.settings.AbstractScopedSettings.SettingUpdater in project crate by crate.
