<div class="type-signature"><span class="modifiers">public interface </span><span class="element-name type-name-label">Emptiable</span></div>
<div class="block">Interface of classes for which empty instances may exist.
This interface is typically used for filtering empty elements from a tree of objects.
Some examples of emptiable classes are:
<ul>
<li><a href="../measure/Range.html" title="class in org.apache.sis.measure"><code>Range</code></a> when the lower bounds is equal to the upper bounds and at least
one bound is exclusive.</li>
<li><a href="../../../../../org.apache.sis.metadata/org/apache/sis/metadata/AbstractMetadata.html" title="class in org.apache.sis.metadata"><code>Abstract­Metadata</code></a> when no property value has been given to the metadata,
or all properties are themselves empty.</li>
<li><a href="../../../../../org.apache.sis.referencing/org/apache/sis/geometry/AbstractEnvelope.html" title="class in org.apache.sis.geometry"><code>Abstract­Envelope</code></a> when the span, surface or volume inside the envelope
is zero.</li>
</ul>
SIS collections do <strong>not</strong> implement this interface even if they provide a <code>is­Empty()</code> method,
for consistency with collections in <code>java​.util</code> and other libraries. This policy avoid duplicated calls to
<code>is­Empty()</code> methods when the caller needs to check for both <code>Collection</code> and <code>Emptiable</code> interfaces.</div>
