Class Routing::Node

A node in a routing tree modeling the composition of middleware functions and route handlers.

More precisely, this is a node in a graph representing a set of possible routing trees, as the concrete shape of the routing tree may be depend on branching control flow.

Each node represents a function that can receive an incoming request, though not necessarily a function with an explicit body in the source code.

A node may either consume the request, dispatching to its first child, or pass it on to its successor in the tree. The successor is the next sibling, or in case there is no next sibling, it is the next sibling of the first ancestor that has a next sibling.

Predicates

definitelyResumesDispatch	Like `mayResumeDispatch` but without the assumption that functions with an unknown implementation invoke their continuation.
getAChild	Gets a child of this node in the routing tree.
getFirstChild	Gets the first child of this node in the routing tree.
getLastChild	Gets the last child of this node in the routing tree.
getNextSibling	Gets the next sibling of this node in the routing tree.
getOwnHttpMethod	Gets an HTTP method name which this node will accept, or nothing if the node accepts all HTTP methods, not taking into account the context from ancestors or children nodes.
getParent	Gets the parent of this node in the routing tree.
getPreviousSibling	Gets the previous sibling of this node in the routing tree.
getRelativePath	Gets a path prefix to be matched against the path of incoming requests.
getRootNode	Gets the root node of this node in the routing tree.
getRouteInstallation	Gets a place where this route node is installed as a route handler.
getValueImplicitlyStoredInAccessPath	Gets a node whose value can be accessed via the given access path on the `n`th route handler parameter, from any route handler that follows after this one.
hasLocationInfo	Holds if this element is at the specified location. The location spans column `startcolumn` of line `startline` to column `endcolumn` of line `endline` in file `filepath`. For more information, see Locations.
isGuardedBy	Holds if the middleware corresponding to `node` has processed the incoming request strictly prior to this node.
isGuardedByNode	Holds if `node` has processed the incoming request strictly prior to this node.
mayResumeDispatch	Holds if this node may invoke its continuation after having dispatched the request to its children, that is, the incoming request may be partially processed by this subtree, and subsequently passed on to the successor.
toString	Gets a textual representation of this element.
