Function CombineOperationParameters

pkg/codegen/operations.go:1376–1403

CombineOperationParameters combines the Parameters defined at a global level (Parameters defined for all methods on a given path) with the Parameters defined at a local level (Parameters defined for a specific path), preferring the locally defined parameter over the global one

(globalParams []ParameterDefinition, localParams []ParameterDefinition)
