Examples with DataType com.revolsys.datatype.DataType used on opensource projects

Example 21 with DataType

use of com.revolsys.datatype.DataType in project com.revolsys.open by revolsys.

the class GeometryFactory method getGeometryDataTypes.

private static Set<DataType> getGeometryDataTypes(final Collection<? extends Geometry> geometries) {
    final Set<DataType> dataTypes = new LinkedHashSet<>();
    for (final Geometry geometry : geometries) {
        final DataType dataType = geometry.getDataType();

    }
    return dataTypes;
}

Example 22 with DataType

use of com.revolsys.datatype.DataType in project com.revolsys.open by revolsys.

the class GeometryFactory method buildGeometry.

/**
 *  Build an appropriate <code>Geometry</code>, <code>MultiGeometry</code>, or
 *  <code>GeometryCollection</code> to contain the <code>Geometry</code>s in
 *  it.
 * For example:<br>
 *
 *  <ul>
 *    <li> If <code>geomList</code> contains a single <code>Polygon</code>,
 *    the <code>Polygon</code> is returned.
 *    <li> If <code>geomList</code> contains several <code>Polygon</code>s, a
 *    <code>MultiPolygon</code> is returned.
 *    <li> If <code>geomList</code> contains some <code>Polygon</code>s and
 *    some <code>LineString</code>s, a <code>GeometryCollection</code> is
 *    returned.
 *    <li> If <code>geomList</code> is empty, an empty <code>GeometryCollection</code>
 *    is returned
 *  </ul>
 *
 * Note that this method does not "flatten" Geometries in the input, and hence if
 * any MultiGeometries are contained in the input a GeometryCollection containing
 * them will be returned.
 *
 *@param  geometries  the <code>Geometry</code>s to combine
 *@return           a <code>Geometry</code> of the "smallest", "most
 *      type-specific" class that can contain the elements of <code>geomList</code>
 *      .
