RaveGeoQuery.Query Property

Gets or sets an optional RaveGeo query string.

Syntax

public System.String Query { get; set; }

Property Value

Type: System.String
Default: ""
A RaveGeo query string.

Remarks

A query string that transforms a query to a RaveGeo filter chain and a set of parameters for RaveGeo.

The query should be specified in a format similar to the where clause in a subset of SQL.

The allowed queries are basically:

attribute <relop> constant [AND attribute <relop> constant]*

<relop> is one of =, <>, >, >=, <, <=. Attributes and constants may be enclosed in single or double quotes. Comparisons are non case sensitive.

Also supported (but very limited) is the query:

OBJECTID IN (id [,id]*)

There are also some parameters that are specified like attributes that have a special meaning to RaveGeo (relop must be = for these):

$level - specifies a resolution level, if not specified one is selected for the present scale

$resolutionFactor - when $level is not specified then this increases or decreases the resolution

$connected - set to true if objects should be returned connected

$asynchronous - if set to true data is requested but only the data that is currently in the client is returned

$filter - used for extracting boundary links and may have the values Boundaries, ExteriorBoundaries or InteriorBoundaries

Examples:

Only GeoObjects with an attribute KKOD with value between 3 and 6 will be read. Reading will only be done from level 3

KKOD>3 and KKOD<6 and $level=3

Only the exterior boundaries of GeoObjects with an attribute CityName with value New York will be read.

$filter=ExteriorBoundaries and CityName="New York"

Platforms

Windows, Linux
