== Overview ==

AvatarServicesConnector is the simulator-side remote connector for IAvatarService. It translates IAvatarService calls into HTTP POST requests to the ROBUST Avatar handler at /avatar.

Source file:

OpenSim/Services/Connectors/Avatar/AvatarServicesConnector.cs

----

=== Initialisation ===

Config section: [AvatarService]

Required key:
* AvatarServerURI -- URL of the ROBUST avatar endpoint; throws if missing

Base class BaseServiceConnector.Initialise() called for auth setup.

Three constructors:
* Default (no args) -- URI must be set externally
* String URI -- used by callers that pass the URI directly
* IConfigSource -- calls Initialise(), normal grid mode

----

=== Transport ===

All methods POST to m_ServerURI + "/avatar" using SynchronousRestFormsRequester.

All requests include:
* VERSIONMIN / VERSIONMAX -- protocol version negotiation
* METHOD -- identifies the operation

----

=== Methods ===

{| class="wikitable"
! Method !! METHOD field !! Notes
|-
| GetAvatar(userID) || "getavatar" || Returns AvatarData constructed from result dictionary; null on empty reply or missing result
|-
| GetAppearance(userID) || (none) || Calls GetAvatar(), then avatar.ToAvatarAppearance()
|-
| SetAvatar(userID, avatar) || "setavatar" || Serializes avatar via ToKeyValuePairs(); returns bool from result field
|-
| SetAppearance(userID, appearance) || (none) || Constructs AvatarData from AvatarAppearance, calls SetAvatar()
|-
| ResetAvatar(userID) || "resetavatar" || Returns bool from result field
|-
| SetItems(userID, names[], values[]) || "setitems" || Sends Names and Values as parallel List<string>; returns bool
|-
| RemoveItems(userID, names[]) || "removeitems" || Sends Names as List<string>; returns bool
|}

All write methods (SetAvatar, ResetAvatar, SetItems, RemoveItems) check replyData["result"].ToLower() == "success" and return false on empty reply, missing result field, or exception.

----

=== Notes ===

* The log message in ResetAvatar() says "SetItems reply" in both the missing-result and empty-reply branches -- copy-paste error from SetItems(). The method itself is correct; only the log text is wrong.
* ScopeID fields are present in the code but commented out throughout.
