use of org.apache.atlas.typesystem.exception.EntityExistsException in project incubator-atlas by apache.

the class EntityResource method updateByUniqueAttribute.

/**
     * Adds/Updates given entity identified by its unique attribute( entityType, attributeName and value)
     * Updates support only partial update of an entity - Adds/updates any new values specified
     * Updates do not support removal of attribute values
     *
     * @param entityType the entity type
     * @param attribute the unique attribute used to identify the entity
     * @param value the unique attributes value
     * @param request The updated entity json
     * @return response payload as json
     * The body contains the JSONArray of entity json. The service takes care of de-duping the entities based on any
     * unique attribute for the give type.
