Types

type Matcher

type Matcher struct {
	ObjGVK    schema.GroupVersionKind
	Operation configv1alpha1.InterpreterOperation
	Rule      configv1alpha1.RuleWithOperations
}

Matcher determines if the Object matches the Rule.

func (*Matcher) Matches

func (m *Matcher) Matches() bool

Matches tells if the Operation, Object matches the Rule.

type NameValue

	Name() string
	// Document explains detail of rule.
	Document() string
	// GetScript returns the script for the rule from customization. If not enabled, return empty
	GetScript(*configv1alpha1.ResourceInterpreterCustomization) string
	// SetScript set the script for the rule. If script is empty, disable the rule.
	SetScript(*configv1alpha1.ResourceInterpreterCustomization, string)
	// Run execute the rule with given args, and return the result.
	Run(*declarative.ConfigurableInterpreter, RuleArgs) *RuleResult
}

Rule known how to get and set script for interpretation rule, and can execute the rule with given args.

type RuleArgs
