 <div class="block">Abstraction of a real-world phenomena. A <code>FeatureType</code> instance describes the class of all
  <a href="AbstractFeature.html" title="class in org.apache.sis.feature">feature</a> instances of that type.

  <div class="note"><b>Analogy:</b>
  compared to the Java language, <code>FeatureType</code> is equivalent to <a href="https://docs.oracle.com/en/java/javase/11/docs/api/java.base/java/lang/Class.html" title="class or interface in java.lang" class="external-link"><code>Class</code></a> while
  <code>Feature</code> instances are equivalent to <a href="https://docs.oracle.com/en/java/javase/11/docs/api/java.base/java/lang/Object.html" title="class or interface in java.lang" class="external-link"><code>Object</code></a> instances of that class.</div>

  <div class="warning"><b>Warning:</b>
  This class is expected to implement a GeoAPI <code>FeatureType</code> interface in a future version.
  When such interface will be available, most references to <code>DefaultFeatureType</code> in the API
  will be replaced by references to the <code>FeatureType</code> interface.</div>

  <h2 id="naming-heading">Naming</h2>
  The feature type <a href="AbstractIdentifiedType.html#getName()">name</a> is mandatory and should be unique. Those names are the main
  criterion used for deciding if a feature type <a href="#isAssignableFrom(org.apache.sis.feature.DefaultFeatureType)">is assignable from</a> another type.
  Names can be <a href="../../../../../org.apache.sis.metadata/org/apache/sis/util/iso/DefaultScopedName.html" title="class in org.apache.sis.util.iso">scoped</a> for avoiding name collision.

  <h2 id="properties-and-inheritance-heading">Properties and inheritance</h2>
  Each feature type can provide descriptions for the following <a href="#getProperties(boolean)">properties</a>:

  <ul>
    <li><a href="DefaultAttributeType.html" title="class in org.apache.sis.feature">Attributes</a></li>
    <li><a href="DefaultAssociationRole.html" title="class in org.apache.sis.feature">Associations to other features</a></li>
    <li><a href="AbstractOperation.html" title="class in org.apache.sis.feature">Operations</a></li>
  </ul>

  In addition, a feature type can inherit the properties of one or more other feature types.
  Properties defined in the sub-type can override properties of the same name defined in the
  <a href="#getSuperTypes()">super-types</a>, provided that values of the sub-type property are
  assignable to the super-type property.

  <div class="note"><b>Analogy:</b> compared to the Java language, the above rule is similar to overriding a method
  with a more specific return type (a.k.a. <cite>covariant return type</cite>). This is also similar to Java arrays,
  which are implicitly <cite>covariant</cite> (i.e. <code>String[]</code> can be casted to <code>CharSequence[]</code>, which
  is safe for read operations but not for write operations — the latter may throw <a href="https://docs.oracle.com/en/java/javase/11/docs/api/java.base/java/lang/ArrayStoreException.html" title="class or interface in java.lang" class="external-link"><code>ArrayStoreException</code></a>).</div>

  <h2 id="instantiation-heading">Instantiation</h2>
  <code>DefaultFeatureType</code> can be instantiated directly by a call to its <a href="#%3Cinit%3E(java.util.Map,boolean,org.apache.sis.feature.DefaultFeatureType%5B%5D,org.apache.sis.feature.AbstractIdentifiedType...)">constructor</a>.
  But a more convenient approach may be to use the <a href="builder/FeatureTypeBuilder.html" title="class in org.apache.sis.feature.builder"><code>FeatureTypeBuilder</code></a> instead,
  which provides shortcuts for frequently-used operations like creating various <a href="http://www.geoapi.org/3.0/javadoc/org.opengis.geoapi/org/opengis/util/GenericName.html" title="class or interface in org.opengis.util" class="external-link"><code>GenericName</code></a>
  instances sharing the same namespace.

  <h2 id="immutability-and-thread-safety-heading">Immutability and thread safety</h2>
  Instances of this class are immutable if all properties (<a href="http://www.geoapi.org/3.0/javadoc/org.opengis.geoapi/org/opengis/util/GenericName.html" title="class or interface in org.opengis.util" class="external-link"><code>GenericName</code></a> and <a href="http://www.geoapi.org/3.0/javadoc/org.opengis.geoapi/org/opengis/util/InternationalString.html" title="class or interface in org.opengis.util" class="external-link"><code>InternationalString</code></a>
  instances) and all arguments (<code>AttributeType</code> instances) given to the constructor are also immutable.
  Such immutable instances can be shared by many objects and passed between threads without synchronization.</div>
