Package com.codename1.maps.vector

package com.codename1.maps.vector

The pure-vector map rendering engine that backs MapView.

The engine decodes Mapbox Vector Tiles (MVT) with the framework protobuf reader and draws them entirely through the Codename One Graphics API -- there is no native peer, so a MapView composes with regular lightweight UI on every platform including the simulator and the browser. Tiles are supplied by a pluggable TileSource (network MVT or raster, bundled fixtures, or the keyless OpenFreeMap basemap) and styled with a MapStyle (a subset of the MapLibre GL style specification). The classes in this package are internal building blocks of the engine; application code targets MapView and the public tile-source and style types.

Package	Description
com.codename1.maps	The mapping API allows developers to use maps in their applications, add layers on top of the map and to enhance the API with additional Layers, Providers and functionality.
com.codename1.maps.layers	The Layers are elements that are displayed on the map.
com.codename1.maps.providers	These are the map providers, currently http://www.openstreetmap.org/ is supported.
com.codename1.maps.spi	The maps service-provider interface (SPI).

Class	Description
BundledTileSource	A TileSource that loads tiles from application resources bundled into the app (the classpath), with no network access.
DemoTileSource	A self-contained TileSource that synthesizes a deterministic Mapbox Vector Tile in memory for every address, with no network or bundled assets.
HttpTileSource	A TileSource that fetches tiles over HTTPS from a slippy-map URL template.
MapStyle	An ordered list of StyleLayer rules plus a background color, describing how a vector tile is painted.
MvtDecoder	Decodes a Mapbox Vector Tile (MVT 2.1, application/x-protobuf) into the in-memory VectorTile model using the framework's protobuf reader (ProtoReader).
MvtTileSource	A networked MVT (Mapbox Vector Tile) source.
RasterTileSource	A networked raster (image) XYZ tile source.
StyleLayer	One rule of a MapStyle: it selects features from a named vector-tile source layer (optionally narrowed by a single attribute equality filter) within a zoom range, and describes how to paint them.
TileCallback	Asynchronous result callback for TileSource.fetchTile(int, int, int, TileCallback).
TileSource	Supplies tile payloads to the VectorMapEngine given a slippy-map z/x/y address.
VectorFeature	A single decoded feature of a Mapbox Vector Tile: its geometry type, its attribute map, and its geometry as one or more parts in tile-local coordinates (0..VectorLayer.getExtent(), origin top-left).
VectorLayer	A named layer of a decoded vector tile (for example water, road, building, place) holding its features and the integer extent of its local coordinate grid (4096 by default).
VectorMapEngine	The pure-Codename One map renderer behind MapView (and the NativeMap fallback).
VectorTile	A decoded Mapbox Vector Tile: an ordered collection of named VectorLayers.
WebMercator	Spherical Web Mercator (EPSG:3857) helpers expressed in "world pixels" -- the slippy-map coordinate space where the whole world spans tileSize * 2^zoom pixels.
