Examples with BasicBeanDescription com.fasterxml.jackson.databind.introspect.BasicBeanDescription used on opensource projects

Example 1 with BasicBeanDescription

use of com.fasterxml.jackson.databind.introspect.BasicBeanDescription in project dropwizard-guicey by xvik.

the class ConfigTreeBuilder method resolvePaths.

/**
 * Use jackson serialization api to extract all configuration values with paths from configuration object.
 * Always analyze types, even if actual branch is not present at all (null value) in order to always bind
 * nulls and avoid "Schrodinger's binding" case. In short, bindings should not depend on configuration values
 * (presence).
 * <p>
 * Still, bindings may vary: for example, bound implementations may differ (best example is dropwizard server type),
 * as a consequences, parsed type may be different and so different properties paths could be recognized.
 *
 * @param config  jackson serialization config
 * @param content currently parsed paths
 * @param type    analyzed part type
 * @param object  analyzed part instance (may be null)
 * @return all configuration paths values
