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 the org.apache.sis.metadata
package javadoc.

Null values, nil objects and collections
All constructors and setter methods accept null
arguments.
A null argument value means that the metadata element can not 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.
