/**
|
* A feature table for use with the <code>EXT_mesh_features</code> extension or
|
* legacy <code>EXT_feature_metadata</code> glTF extension. It also includes some
|
* options to be compatible with the 3D Tiles 1.0 batch table.
|
* <p>
|
* For batch tables, properties are resolved in the following order:
|
* </p>
|
* <ol>
|
* <li>binary properties from options.metadataTable</li>
|
* <li>JSON properties from options.jsonMetadataTable</li>
|
* <li>batch table hierarchy properties from options.batchTableHierarchy</li>
|
* </ol>
|
* <p>
|
* See the {@link https://github.com/CesiumGS/glTF/tree/3d-tiles-next/extensions/2.0/Vendor/EXT_mesh_features|EXT_mesh_features Extension} as well as the
|
* previous {@link https://github.com/CesiumGS/glTF/tree/3d-tiles-next/extensions/2.0/Vendor/EXT_feature_metadata|EXT_feature_metadata Extension} for glTF.
|
* </p>
|
*
|
* @param {Object} options Object with the following properties:
|
* @param {String} [options.name] Human-readable name to describe the table
|
* @param {String|Number} [options.id] A unique id to identify the feature table, useful for debugging. For <code>EXT_mesh_features</code>, this is the array index in the feature tables array, for <code>EXT_feature_metadata</code> this is the dictionary key in the feature tables dictionary.
|
* @param {Number} options.count The number of features in the table.
|
* @param {MetadataTable} [options.metadataTable] A table of binary properties.
|
* @param {JsonMetadataTable} [options.jsonMetadataTable] For compatibility with the old batch table, free-form JSON properties can be passed in.
|
* @param {BatchTableHierarchy} [options.batchTableHierarchy] For compatibility with the <code>3DTILES_batch_table_hierarchy</code> extension, a hierarchy can be provided.
|
* @param {Object} [options.extras] Extra user-defined properties
|
* @param {Object} [options.extensions] An object containing extensions
|
*
|
* @alias PropertyTable
|
* @constructor
|
*
|
* @private
|
* @experimental This feature is using part of the 3D Tiles spec that is not final and is subject to change without Cesium's standard deprecation policy.
