Types ¶
type Evaluator ¶
type Evaluator interface {
Eval(ctx context.Context, e parser.Expr, from, until int64, values map[parser.MetricRequest][]*types.MetricData) ([]*types.MetricData, error)
}
Evaluator is a interface for any existing expression parser
type Function ¶
type Function interface { SetEvaluator(evaluator Evaluator) GetEvaluator() Evaluator Do(ctx context.Context, e parser.Expr, from, until int64, values map[parser.MetricRequest][]*types.MetricData) ([]*types.MetricData, error) Description() map[string]types.FunctionDescription }
Function is interface that all graphite functions should follow
type FunctionBase ¶
type FunctionBase struct {
Evaluator Evaluator
}
FunctionBase is a set of base methods that partly satisfy Function interface and most probably nobody will modify
func (*FunctionBase) GetEvaluator ¶
func (b *FunctionBase) GetEvaluator() Evaluator
GetEvaluator returns evaluator
func (*FunctionBase) SetEvaluator ¶
func (b *FunctionBase) SetEvaluator(evaluator Evaluator)
SetEvaluator sets evaluator
type FunctionMetadata ¶ added in v0.11.0
type RewriteFunction ¶ added in v0.11.0
type RewriteFunction interface { SetEvaluator(evaluator Evaluator) GetEvaluator() Evaluator Do(ctx context.Context, e parser.Expr, from, until int64, values map[parser.MetricRequest][]*types.MetricData) (bool, []string, error) Description() map[string]types.FunctionDescription }
Function is interface that all graphite functions should follow
type RewriteFunctionMetadata ¶ added in v0.11.0
type RewriteFunctionMetadata struct { Name string Filename string Order Order F RewriteFunction }
