Inheritance diagram for LLHTTPNode:
Responses | |
Most subclasses override one or more of these methods to provide the service. By default, the rest of the LLHTTPNode architecture will handle requests, create the needed LLIOPump, parse the input to LLSD, and format the LLSD result to the output.
The default implementation of each of these is to call response->methodNotAllowed(); The "simple" versions can be overridden instead in those cases where the service can return an immediately computed response. | |

URL traversal | |
The tree is traversed by calling getChild() with successive path components, on successive results. When getChild() returns null, or there are no more components, the last child responds to the request.
The default behavior is generally correct, though wildcard nodes will want to implement validate(). | |
virtual LLHTTPNode * | getChild (const std::string &name, LLSD &context) const |
virtual bool | handles (const LLSD &remainder, LLSD &context) const |
virtual bool | validate (const std::string &name, LLSD &context) const |
const LLHTTPNode * | traverse (const std::string &path, LLSD &context) const |
Child Nodes | |
The standard node can have any number of child nodes under fixed names, and optionally one "wildcard" node that can handle all other names. Usually, child nodes are add through LLHTTPRegistration, not by calling this interface directly.
The added node will be now owned by the parent node. | |
virtual void | addNode (const std::string &path, LLHTTPNode *nodeToAdd) |
LLSD | allNodePaths () const |
Returns an arrary of node paths at and under this node. | |

class | Response |
Users of the HTTP responder will typically derive a class from this one, implement the get(), put() and/or post() methods, and then use LLHTTPRegistration to insert it into the URL tree.
The default implementation handles servicing the request and creating the pipe fittings needed to read the headers, manage them, convert to and from LLSD, etc.

const LLChainIOFactory * LLHTTPNode::getProtocolHandler | ( | ) | const [virtual] |
Return a factory object for handling wire protocols. The base class returns NULL, as it doesn't know about wire protocols at all. This is okay for most nodes as LLIOHTTPServer is smart enough to use a default wire protocol for HTTP for such nodes. Specialized subclasses that handle things like XML-RPC will want to implement this. (See LLXMLSDRPCServerFactory.)

called only on wildcard nodes, to check if they will handle the name; default is false; overrides will want to check name, and return true if the name will construct to a valid url. For convenience, the getChild()
method above will automatically insert the name in context["request"]["wildcard"][key] if this method returns true. For example, the node "agent/<agent_id>/detail" will set context["request"]["wildcard"]["agent_id"] eqaul to the value found during traversal.
