Page Comparison

The ArcGIS REST map engine is similar to the ArcGIS Soap map engine but it utilises the ArcGIS REST API to communicate with ArcGIS, rather than the SOAP API used by the ArcGIS SOAP mapengine.

Properties

Name	Type	Required	Default	Description
id	string	yes		Unique identifier for this map engine, will be used by other items to refer to this map engine
url	string	yes		The URL used to connect to the ArcGIS server, e.g. `http://vmbreakout:6080/arcgis/rest/services/Topo250/MapServer`
mapcache	boolean	no	false	Should a tile cache be used (if it's available). If this is false or not set then any tile cache generated for the map service won't be used
username	string	no		A username to connect to the server as
password	string	no		A password to connect to the server as, should be encrypted using 'encrypt' at the OSGi prompt
usename	boolean	no	false	Use the layer name to refer to individual layers, especially useful when building a ToC model since the names don't change as often as the id. You should ensure that the layer name is unique if you set this to true. If not set or set to false then the layer identifiers for each layer (which are used in ToC models, amongst other things) will be taken from the order that the layer appears within the .mxd file, which can change if layers are added/removed from the .mxd file. If set to true then the label that appears in the .mxd file will be used as the identifier instead
transparent	boolean	no	false	If true then ArcGIS is asked to generate an image that is transparent where no map data is drawn
layers	urn:layers	no		Alter the layer information from ArcGIS
legend	urn:legend	no		Alter the display of the legend
direct	boolean	no	false	If true then Weave will send the URL's returned from ArcGIS directly to the client rather than proxying them on behalf of ArcGIS. This will help performance if ArcGIS is accessed internally and the clients can access the URL's the ArcGIS returns.
referer	string	no		Referer header value when sending HTTP requests to ArcGIS server (since com.cohga.server.map.arcgis.ws bundle version 2.38.48) This is useful if ArcGIS server filters all requests by header value by comparing the referer domain against a list of white-listed domains.
ignoregroups	boolean	no	true	Should Weave ignore the groups when working with ArcGIS map documents. When Weave works with map layers it only deals with the layers themselves, groups don't come into play until you start creating a ToC model, and even then the grouping in ToC models is not used when referring to map layers (they're only used internally on the client to turn on/off a collection of individual layers). Normally this works fine for ArcGIS as Weave will ensure that if a layer is "visible", then all of its parent groups (on the ArcGIS side) will also be turned on. This ensures that the layer is actually visible (as a layer won't be displayed if it's visible but one or more of its parents aren't). This way you can setup your AGS map document however you want (with or without groups) and have the Weave ToC model be the single source of group related information for the ToC panel, and then Weave will ensure that the map layers that need to be drawn are drawn. However, sometimes it's desirable to have Weave recognize the groups (that's the ArcGIS map document groups, not ToC model groups) and have them treated as layers. By setting `ignoregroups` to `false` Weave will include entries in the map engine description for the groups as well as for the layers. In this case the ToC model and the ArcGIS map document groups will, in combination, be responsible for determining whether a layer is visible or not.
username	string	no		Username used to generate tokens. You should no set this, but instead include it in the tokenservice configuration
password	string	no		Password used to generate tokens. You should no set this, but instead include it in the tokenservice configuration
tokenservice	string or urn:tokenservice	no		This can be a simple string providing the token service URL to override the one provided by ArcGIS, in which case you will need to set username and password properties above too, but you should use this as a sub-tag and include all the required information inside of that instead.

Properties

Name	Type	Required	Description
id	number	no	The id of the layer to match
name	string	no	The name of the layer to match

Sub-tags

None

Content

The id or name, depending upon the usename property, of the layer to match

Notes

The layer tag support two formats, one using the id and/or name attributes and the other using the tags content
Either one or both of the id and/or name attributes must be set OR tag content must be provided
If the content of the layer tag is used then the value of the usename property determines if the content should match the layer id or the layer name
Both the id and name attributes can be set, but they must match both values for the layer that you're trying to filter or they won't match the layer

tokenservice

Provide the configuration information to allow Weave to talk to ArcGIS to generate tokens for authentication

Properties

Name	Type	Required	Description
username	string	no	Used with password when requesting a token from ArcGIS
password	string	no	Used with username when requesting a token from ArcGIS
token	string	no	Can be provided instead of username and password and will be used when requesting a token from ArcGIS
url	string	no	To override the token generation endpoint that ArcGIS provides you can set this value to the URL to use instead.
timeout	integer	no	Number of seconds to timeout connections and requests sent to the token generation endpoint default is 0, which mean use the default system timeout
connectiontimeout	integer	no	Number of seconds to timeout the connections to the token service
readtimeout	integer	no	Number of seconds to timeout requests sent to the token service

Notes

Either username and password must be provided, or just token.

For the url parameter:

if the value starts with "https://" or "http://" (you should really not use http://) the value will be used as is.
if the value starts with "//" then "https:" will be prepended to the value.
if otherwise the value will be prepended with the schema, host and port used for the map service itself
