/**
|
|
* Checks if one node has a dependency on another node.
|
|
*
|
|
* Determines whether sortingNode1 depends on sortingNode2 by checking if any of
|
|
* sortingNode1's dependency names match any of sortingNode2's dependencies.
|
|
* This is used in dependency-aware sorting to ensure that dependent nodes are
|
|
* placed after their dependencies.
|
|
*
|
|
* Returns false for self-dependency (when both nodes are the same) to prevent
|
|
* circular dependency issues.
|
|
*
|
|
* @example
|
|
*
|
|
* ```ts
|
|
* const nodeA = {
|
|
* name: 'userService',
|
|
* dependencies: ['userService'],
|
|
* dependencyNames: ['logger', 'database'],
|
|
* }
|
|
*
|
|
* const nodeB = {
|
|
* name: 'logger',
|
|
* dependencies: ['logger'],
|
|
* dependencyNames: [],
|
|
* }
|
|
*
|
|
* isNodeDependentOnOtherNode(nodeA, nodeB)
|
|
* // Returns: true (userService depends on logger)
|
|
*
|
|
* isNodeDependentOnOtherNode(nodeB, nodeA)
|
|
* // Returns: false (logger doesn't depend on userService)
|
|
*
|
|
* isNodeDependentOnOtherNode(nodeA, nodeA)
|
|
* // Returns: false (self-dependency check)
|
|
* ```
|
|
*
|
|
* @param sortingNode1 - The node to check for dependencies.
|
|
* @param sortingNode2 - The potential dependency node.
|
|
* @returns True if sortingNode1 depends on sortingNode2, false otherwise.
