Method and mechanism for optimal scope evaluation in scope based hierarchical configuration using evaluated scope propagation technique
View Patent ↗A first and a second local scope definition for a first and a second node in a hierarchical application tree are received where the hierarchical application tree includes application instructions at nodes. A pruned version of the tree is determined by propagating the first local scope definition from the first node to the second, child node. If the two scope definitions are the same type, the second local scope definition is used instead of the first at the second node. Otherwise, both the first and second local scope definitions are used at the second node if they are independent types. Any nodes that are not relevant are pruned and a qualified application is generated using application instructions at the unpruned nodes.
1. A system, comprising:
a processor; and
a memory coupled with the processor, wherein the memory is configured to provide the processor with instructions which when executed cause the processor to:
receive a first local scope definition associated with a first node in a hierarchical application tree and a second local scope definition associated with a second node in the hierarchical application tree, wherein the hierarchical application tree includes application instructions at one or more nodes within the hierarchical application tree;
determine a pruned version of the hierarchical application tree, including by:
propagating the first local scope definition from the first node to the second node which is a child of the first node, including by:
in the event the first local scope definition and the second local scope definition are associated with a same scope type, using the second local scope definition instead of the first local scope definition at the second node, wherein the second local scope definition is the same or narrower compared to the first local scope definition; and
in the event the first local scope definition and the second local scope definition are associated with independent scope types, using both the first local scope definition and the second local scope definition at the second node; and
pruning any nodes from the hierarchical application tree that are not relevant to a particular set of one or more local scope definitions at a given node in order to obtain the pruned version of the hierarchical application tree; and
generate a qualified application using those application instructions at the unpruned nodes in the pruned version of the hierarchical application tree, wherein:
in the event the first local scope definition and the second local scope definition are associated with a same scope type, the qualified application is relevant to the second local scope definition; and
