PROPERTY_PACKAGE

Constructor Summary
`MapLoader()`

Method Summary
`protected GameMap`	`createMap(org.w3c.dom.Element root)` Creates and begins initialization of the map, from the file.
`boolean`	`inMapEditor()` Returns true if we've been told we're loading the map inside the Map Editor.
`protected GameObject`	`instantiateArchetype(Archetype arch)` Takes an Archetype that we parsed, turns it into a GameObject inheriting from the archetype, and copies certain properties from the Archetype to the object.
`protected GameMap`	`instantiateMap(java.lang.String classname, Dimension size)` Instantiates the map class, if possible.
`GameMap`	`instantiatePyMap(java.lang.String filename, Dimension size)` Instantiates a map with a python class in the header.
`protected Terrain`	`instantiateTerrain(Archetype arch)` Instantiates a Terrain object, possibly returning a flyweight version from the global Terrain cache.
`GameMap`	`loadMap(java.lang.String filename)` Reads a map from a Wyvern XML map file.
`protected GameMap`	`loadPythonMap(java.lang.String filename)` Loads a map defined in a python file.
`protected void`	`parseLocalArchetype(org.w3c.dom.Element node)` Parses and initializes a map-local archetype definition.
`protected Dimension`	`parseMapSize(org.w3c.dom.Element header)` Gets width & height attributes, if any, as integers.
`protected GameObject`	`parseObject(org.w3c.dom.Element node)` Parses an object definition, either inline or as an archetype reference, and returns an initialized object.
`protected java.lang.Object`	`readLocation(java.lang.String line)` Reads a location descriptor - a point, rectangle or perhaps eventually some other shape or list of points.
`protected void`	`readObject(GameMap map, org.w3c.dom.Element node, java.lang.String loc)` Reads a single object definition from the map.
`protected void`	`readObjects(GameMap map, org.w3c.dom.Element root)` Reads the object definitions and builds the map.
`protected void`	`setDefaultTerrain(GameMap map)` Transfers the "terrain" property into instance data.
`void`	`setMapEditor(boolean editor)` Sets whether the map is being loaded within the Map Editor
`protected void`	`setMapPath(GameMap map, java.lang.String filename)` Sets the path for the map.
`protected void`	`setObject(GameObject m, GameMap map, int x, int y)` Places an object in the map.
`void`	`throwExceptions(boolean exceptions)` Turns exception-throwing on or off.
`boolean`	`throwingExceptions()` Returns true if this GameMapLoader is configured to throw exceptions when it encounters errors loading a map.

Field Detail

editor_

protected boolean editor_

Set in loadMap from the 'editor' parameter. True if we're loading a map for the map editor.

filename_

protected java.lang.String filename_

map_

protected GameMap map_

objectCount_

protected int objectCount_

throwExceptions_

protected boolean throwExceptions_

monsterCount_

protected int monsterCount_

Keep track of how many monsters or generators we've loaded. If we finish loading the map, and there are no monsters or generators, then we set its default unload-delay to be fairly short, to free up the memory. NOTE: we can't actually DO this until we've fixed the map memory leaks, or it'll just make it worse.

python_

protected static org.python.util.PythonInterpreter python_
