Example 6 with LoaderOptions

use of org.yaml.snakeyaml.LoaderOptions in project spring-framework by spring-projects.

the class YamlProcessor method createYaml.

/**
 * Create the {@link Yaml} instance to use.
 * <p>The default implementation sets the "allowDuplicateKeys" flag to {@code false},
 * enabling built-in duplicate key handling in SnakeYAML 1.18+.
 * <p>As of Spring Framework 5.1.16, if custom {@linkplain #setSupportedTypes
 * supported types} have been configured, the default implementation creates
 * a {@code Yaml} instance that filters out unsupported types encountered in
 * YAML documents. If an unsupported type is encountered, an
 * {@link IllegalStateException} will be thrown when the node is processed.
 * @see LoaderOptions#setAllowDuplicateKeys(boolean)
