Example 1 with EntityResolver

use of eu.esdihumboldt.hale.common.align.io.EntityResolver in project hale by halestudio.

the class AppSchemaMappingUtils method resolvePropertyTypes.

/**
 * Goes through all chain configurations in the provided feature chaining
 * configuration and attempts to resolve all unresolved property entity
 * definitions.
 *
 * <p>
 * More specifically, resolution for a particular chain configuration is
 * attempted if {@link ChainConfiguration#getJaxbNestedTypeTarget()} returns
 * a value, while {@link ChainConfiguration#getNestedTypeTarget()} returns
 * <code>null</code>.
 * </p>
 *
 * <p>
 * Upon successful resolution,
 * {@link ChainConfiguration#setJaxbNestedTypeTarget(PropertyType)} is
 * invoked with a <code>null</code> argument, to avoid further entity
 * resolution attempts.
 * </p>
 *
 * <p>
 * A {@link DefaultEntityResolver} instance is used to resolve entities.
 * </p>
 *
 * @param featureChaining the global feature chaining configuration
 * @param types the schema to use for entity lookup
 * @param ssid the schema space identifier
