Types

type ParameterRouter

type ParameterRouter interface {

	// First pass assignment of columnar objects
	// to tables, only for HTTP method parameters.  All data accrual is done herein:
	//   - SQL parser table objects mapped to hierarchy.
	//   - Data flow dependencies identified and persisted.
	//   - Hierarchies may be persisted for analysis.
	// Detects bi-directional data flow errors and returns error if so.
	// Returns:
	//   - Hierarchy.
	//   - Columnar objects definitely assigned as HTTP method parameters.
	//   - Error if applicable.
	Route(tb sqlparser.TableExpr, handler handler.HandlerContext) (taxonomy.AnnotationCtx, error)

	// Detects:
	//   - Dependency cycle.
	AnalyzeDependencies() error

	GetOnConditionsToRewrite() map[*sqlparser.ComparisonExpr]struct{}

	GetOnConditionDataFlows() (dataflow.Collection, error)
}

Parameter router supports mapping columnar input to tabular output. This is for dealing with parser objects, prior to assignment of openapi schemas. The storage medium for constituents is abstracted. As of now this is a multi stage object, violates Single functionality.
