Module org.apache.sis.metadata
Package org.apache.sis.metadata.iso.acquisition
package org.apache.sis.metadata.iso.acquisition
Information about the measuring instruments, the platform carrying them, and the mission to which the data contributes.
An explanation for this package is provided in the OpenGIS® javadoc.
The remaining discussion on this page is specific to the SIS implementation.
Overview
For a global overview of metadata in SIS, see theorg.apache.sis.metadata

Null values, nil objects and collections
All constructors and setter methods acceptnull
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 NilObject
s.
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.
