Controlled activation of interdependent bindings
A system for efficiently configuring bindings based on a dependency graph is described. The system may generate or access a graph comprising a set of nodes. Each node may represent a binding and is associated with a component property of a component hierarchy corresponding to a hierarchical structure of a data model. Each node of the graph may be connected to at least one other node with an edge representing a dependency in the hierarchical structure of the data model. The system may receive a request to generate a view associated with the set of bindings. The system may determine an order to load the set of bindings based on the graph, and may load the set of bindings based on the determined order.
1 . A computer-implemented method comprising:
receiving a request to populate a graphic user interface with a view associated with a set of bindings each associated with a component property of a real-world physical component;
determining an order to load the set of bindings to account for a startup lag caused by loading bindings and dependencies associated with the bindings by first loading bindings without dependencies and afterwards loading each dependent binding only after each binding on which the dependent binding depends has produced valid data, wherein the order further accounts for a detected binding dependency loop by randomly selecting an order in which bindings within the binding dependency loop are loaded;
loading the set of bindings within the view based on the determined order; and
while loading the set of bindings, monitoring configuration results from loaded bindings using a programmable logic controller physically coupled to the real-world physical component and configured to monitor and control one or more physical states associated with the real-world physical component, and delaying loading of a set of subsequent bindings until the monitored configuration results include successfully returned outputs detected by the programmable logic controller from all bindings on which the set of subsequent bindings depend.
2 . The computer-implemented method of claim 1 , wherein the graph is generated by traversing a hierarchical set of nodes to identify the set of bindings.
3 . The computer-implemented method of claim 2 , wherein nodes of the graph are generated based on each identified binding while traversing the hierarchical set of nodes.
4 . The computer-implemented method of claim 2 , wherein each edge of the graph is directional indicating a direction of dependency between the nodes coupled to the edge, and wherein determining the order to load the set of bindings comprises:
identifying within the graph a first set of nodes with no outgoing edges;
identifying a second set of nodes that are directly connected to the first set of nodes; and
loading the first set of nodes before loading the second set of nodes.
5 . The computer-implemented method of claim 2 , further comprising:
removing a cycle from the graph, wherein the cycle is not associated with an originating node.
6 . The computer-implemented method of claim 1 , wherein a binding is a tag binding, a property binding, an expression binding, an expression structure binding, a query binding, a tag history binding, or an HTTP (Hypertext Transfer Protocol) binding.
