# Properties
# beginpos
• Optional beginpos: number
记录开始位置.
# bounds
• Optional bounds: [number, number, number, number]
范围.
# condition
• condition: string
条件.
# fields
• Optional fields: string
是返回的字段列表，多个之是用逗号,分开,如. "name,objectid"
Inherited from: IQueryBaseFeatures.fields
# geom
• Optional geom: boolean
是否为几何图形查询.
Inherited from: IQueryBaseFeatures.geom
# includegeom
• Optional includegeom: boolean
是否返回几何数据,为了性能问题，realgeom为false时，如果返回条数大于1.只会返回每个实体的外包矩形，如果条数为1的话，会返回此实体的真实geojson；realgeom为true时每条都会返回实体的geojson
# isContains
• Optional isContains: boolean
是否为包含关系, true为包含关系,false为相交关系，默认false. (传入了bounds进行范围查询时有效)
# layer
• Optional layer: string
图层名称（为空时采用当前打开的地图图层名称).
Inherited from: IQueryBaseFeatures.layer
# limit
• Optional limit: number
返回最多的记录条数.
Inherited from: IQueryBaseFeatures.limit
# mapid
• Optional mapid: string
地图ID(为空时采用当前打开的mapid).
Inherited from: IQueryBaseFeatures.mapid
# realgeom
• Optional realgeom: boolean
是否返回真实实体几何geojson.与 includegeom参数，结合使用。参考includegeom的用法
# simplifyTolerance
• Optional simplifyTolerance: boolean
GeoJSON几何数据简化墨托卡距离，默认为零，不简化。例如允许10级别以上一个像素级别的误差，可用 map.pixelToGeoLength(1, 10) * vjmap.Projection.EQUATORIAL_SEMIPERIMETER * 2 / map.getGeoBounds(1.0).width()
Inherited from: IQueryBaseFeatures.simplifyTolerance
# toMapCoordinate
• Optional toMapCoordinate: boolean
查询返回的坐标默认为墨卡托坐标，返回会程序会自动转化为cad坐标，如果要直接返回cad地图坐标，需要把toMapCoordinate设置为true.
Inherited from: IQueryBaseFeatures.toMapCoordinate
# useCache
• Optional useCache: boolean
启动cache(内存打开的图形有效).
Inherited from: IQueryBaseFeatures.useCache
# version
• Optional version: string
地图版本(为空时采用当前打开的地图版本).
Inherited from: IQueryBaseFeatures.version
# zoom
• Optional zoom: number
当前级别.
Inherited from: IQueryBaseFeatures.zoom
