Package org.apache.sis.metadata.iso.quality


package org.apache.sis.metadata.iso.quality
Information about data quality, accuracy and consistency of a dataset. An explanation for this package is provided in the OpenGIS® javadoc. The remaining discussion on this page is specific to the SIS implementation.

Null values, nil objects and collections

All constructors and setter methods accept null arguments. A null argument value means that the metadata element cannot be provided, and the reason for that is unspecified. Alternatively, users can specify why a metadata element is missing by providing a value created by Nil­Reason​.create­Nil­Object(Class).

Unless otherwise noted in the Javadoc, all getter methods may return an empty collection, an empty array or null if the type is neither a collection or an array. Note that non-null values may be Nil­Objects.

Unless the metadata object has been marked as unmodifiable and unless otherwise noted in the Javadoc, all collections returned by getter methods are live: adding new elements in the collection modify directly the underlying metadata object.
