Each time a feature is added, changed or removed * from the batch, these inner batches are modified accordingly in order to keep them up-to-date. * * A feature can be present in several inner batches, for example a polygon geometry will be present in the polygon batch * and its linear rings will be present in the line batch. Multi geometries are also broken down into individual geometries * and added to the corresponding batches in a recursive manner. * * Corresponding {@link module:ol/render/webgl/BatchRenderer} instances are then used to generate the render instructions * and WebGL buffers (vertices and indices) for each inner batches; render instructions are stored on the inner batches, * alongside the transform used to convert world coords to screen coords at the time these instructions were generated. * The resulting WebGL buffers are stored on the batches as well. * * An important aspect of geometry batches is that there is no guarantee that render instructions and WebGL buffers * are synchronized, i.e. render instructions can describe a new state while WebGL buffers might not have been written yet. * This is why two world-to-screen transforms are stored on each batch: one for the render instructions and one for * the WebGL buffers. */ declare class MixedGeometryBatch { /** * @type {PolygonGeometryBatch} */ polygonBatch: PolygonGeometryBatch; /** * @type {PointGeometryBatch} */ pointBatch: PointGeometryBatch; /** * @type {LineStringGeometryBatch} */ lineStringBatch: LineStringGeometryBatch; /** * @param {Array} features Array of features to add to the batch */ addFeatures(features: Array): void; /** * @param {Feature|RenderFeature} feature Feature to add to the batch */ addFeature(feature: Feature | RenderFeature): void; /** * @param {Feature|RenderFeature} feature Feature * @private */ private clearFeatureEntryInPointBatch_; /** * @param {Feature|RenderFeature} feature Feature * @private */ private clearFeatureEntryInLineStringBatch_; /** * @param {Feature|RenderFeature} feature Feature * @private */ private clearFeatureEntryInPolygonBatch_; /** * @param {import("../../geom").Geometry|RenderFeature} geometry Geometry * @param {Feature|RenderFeature} feature Feature * @private */ private addGeometry_; /** * @param {GeometryType} type Geometry type * @param {Array} flatCoords Flat coordinates * @param {Array | Array> | null} ends Coordinate ends * @param {Feature|RenderFeature} feature Feature * @param {string} featureUid Feature uid * @private */ private addCoordinates_; /** * @param {Feature|RenderFeature} feature Feature */ changeFeature(feature: Feature | RenderFeature): void; /** * @param {Feature|RenderFeature} feature Feature */ removeFeature(feature: Feature | RenderFeature): void; clear(): void; } //# sourceMappingURL=MixedGeometryBatch.d.ts.map
