Class IWGeometryFilter

main class to filter geometries

IWGeometryFilter

IWGeometryFilter()

clear

clear(map)

resets the geometryFilter (removes renderers and shapes)

Parameters:
IWMap map - the map

drawGetLayerResult

drawGetLayerResult(result, renderingAttributes, highlightingAttributes, map, callback, options)

draw the geometries of the given result object on the map.

Parameters:
object result - the result of getLayer function (contains array of geometries, extent and layer infos)
object renderingAttributes - a set of CSS attributes to render the filtered polygons, e.g. {fill: "red", fillOpacity: 0, stroke: "grey", strokeWidth: 5}
object highlightingAttributes - a set of CSS attributes to render polygons while the cursor hovers above them, e.g. {fill: "blue", fillOpacity: 0.5, stroke: "black", strokeWidth: 8}
IWMap map - the map
function callback - the callback function
object options - set tooltip attribute or textAttributes E.g {tooltip:{value:'$ID$ $NAME$'}, textAttributes:{value:'NAME', renderOptions: {fill: 'red',fontSize: '30px', fontWeight: 'bold'}, boxAttributes: {fill: 'white'}}}

drawLayer

drawLayer(layerId, , filters, renderingAttributes, highlightingAttributes, map, callback, options)

Requests geometry and attributes from the given layer and draw them on the map.

Parameters:
String layerId - layerId of the layer, e.g. KGS
object{ area an area to bound the shapes, e.g. {topleft: "697526, 6759257", bottomright: "789250, 6667533"  - , a bounding box {coord: "726113,6702540", radius: 16758}, a circle {polygon: ["727641,6713853","739566,6726694","749197,6708808"]}, a polygon
array filters - a list of filter objects, e.g. {type: "prefix", key: "PLZ", value: "5"} a prefix filter to select only postal codes starting with 5
object renderingAttributes - a set of CSS attributes to render the filtered polygons, e.g. {fill: "red", fillOpacity: 0, stroke: "grey", strokeWidth: 5}
object highlightingAttributes - a set of CSS attributes to render polygons while the cursor hovers above them, e.g. {fill: "blue", fillOpacity: 0.5, stroke: "black", strokeWidth: 8}
IWMap map - a map
function callback - the callback function
object options - set tooltip attribute or textAttributes E.g {tooltip:{value:'$ID$ $NAME$'}, textAttributes:{value:'NAME', renderOptions: {fill: 'red',fontSize: '30px', fontWeight: 'bold'}, boxAttributes: {fill: 'white'}}}

getLayer

getLayer(layerId, area, filters, zoom, callback)

Requests geometry and attributes from the given layer.

Parameters:
String layerId - ID of the layer, e.g. KGS
object area - an area to bound the shapes, e.g. {topleft: "697526,6759257", bottomright: "789250,6667533"}, a bounding box {coord: "726113,6702540", radius: 16758}, a circle {polygon: ["727641,6713853","739566,6726694","749197,6708808"]}, a polygon
array filters - a list of filter objects, e.g. {type: "prefix", key: "PLZ", value: "5"} a prefix filter to select only postal codes starting with 5
number zoom - preffered zoom level (depends on the zoom range of the layer, if it is out of range no layer is returned). Default is 13
function callback - the callback function

getLayerAttributes

getLayerAttributes(layerId, filters, offset, limit, callback)

Requests items and their attributes from a layer.

Parameters:
String layerId - layerId of the layer, e.g. KGS
array filters - a list of filter objects, e.g. {type: "prefix", key: "PLZ", value: "5"} a prefix filter to select only postal codes starting with 5
number offset - index of the first desired element, can be used for paging. 0 determined!
number limit - number of elements, can be used for paging
function callback - the callback function

getLayers

getLayers(callback)

Lists all available layers.

Parameters:
function callback - function which is called when a result is available

removeLayer

removeLayer(map, layerId)

removes the given layer

Parameters:
IWMap map - the map
String layerId - layerId of the layer, e.g. KGS
