# Properties
# condition
• Optional 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
# 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
# maxGeomBytesSize
• Optional maxGeomBytesSize: number
返回最大的几何字节数.
# pixelToGeoLength
• Optional pixelToGeoLength: number
当前一个像素表示多少几何长度，如果输入了此值，则为此值为主，否则，根据输入的zoom值后台自动计算.
# pixelsize
• Optional pixelsize: number
像素大小.
# 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
# x
• x: number
查询的坐标X.
# y
• y: number
查询的坐标Y.
# zoom
• Optional zoom: number
当前级别.
