Types ¶
type ServiceDependencyGraph ¶
type ServiceDependencyGraph struct {
// contains filtered or unexported fields
}
ServiceDependencyGraph models dependencies between services using adjacency maps. Edge direction: dependency -> dependent (i.e., B -> A means A depends on B).
func BuildServiceDependencyGraph ¶
func BuildServiceDependencyGraph(project *types.Project) (*ServiceDependencyGraph, error)
BuildServiceDependencyGraph builds a dependency graph for all services in a project.
func NewServiceDependencyGraph ¶
func NewServiceDependencyGraph() *ServiceDependencyGraph
NewServiceDependencyGraph creates a new, empty dependency graph.
func (*ServiceDependencyGraph) AddDependency ¶
func (sdg *ServiceDependencyGraph) AddDependency(dependent, dependency string) error
AddDependency adds a dependency relationship where `dependent` depends on `dependency`. This creates an edge: dependency -> dependent.
func (*ServiceDependencyGraph) AddService ¶
func (sdg *ServiceDependencyGraph) AddService(serviceName string) error
AddService ensures a service exists in the graph.
func (*ServiceDependencyGraph) GetDependencies ¶
func (sdg *ServiceDependencyGraph) GetDependencies(serviceName string) ([]string, error)
GetDependencies returns the services that the given service depends on.
func (*ServiceDependencyGraph) GetDependents ¶
func (sdg *ServiceDependencyGraph) GetDependents(serviceName string) ([]string, error)
GetDependents returns the services that depend on the given service.
func (*ServiceDependencyGraph) GetTopologicalOrder ¶
func (sdg *ServiceDependencyGraph) GetTopologicalOrder() ([]string, error)
GetTopologicalOrder returns services in topological order (dependencies first). Kahn's algorithm with deterministic tie-breaking (lexical).
func (*ServiceDependencyGraph) HasCycles ¶
func (sdg *ServiceDependencyGraph) HasCycles() bool
HasCycles checks if the dependency graph contains cycles.
