Example 11 with DataComplexProcessor

use of com.linkedin.data.transform.DataComplexProcessor in project rest.li by linkedin.

the class RestLiDataValidator method validatePatch.

/**
 * Checks that if the patch is applied to a valid entity, the modified entity will also be valid.
 * This method...
 * (1) Checks that required/ReadOnly/CreateOnly fields are not deleted.
 * (2) Checks that new values for record templates contain all required fields (treating ReadOnly fields as optional).
 * (3) Applies the patch to an empty entity and validates the entity for custom validation rules
 *     and Rest.li annotations, allowing the following exceptions:
 *     - Allows required fields to be absent by using {@link RequiredMode#IGNORE},
 *       because a patch does not necessarily contain all fields.
 *     - Allows array-descendant ReadOnly/CreateOnly fields to be set, since there's currently no way to "patch" arrays.
 *
 * @param patchRequest the patch
 * @return the final validation result
