Types ¶
type IndexRender ¶
type IndexRender struct {
// contains filtered or unexported fields
}
func NewIndexRender ¶
func NewIndexRender(t string) *IndexRender
func (*IndexRender) Render ¶
func (r *IndexRender) Render(event map[string]interface{}) (value interface{}, err error)
Render implements ValueRender. note: it's field use "null" as result when error occurs for compatibility
func (*IndexRender) SetTimeLocation ¶
func (r *IndexRender) SetTimeLocation(loc string)
SetTimeLocation parse `location` to time.Location ans set it as its member. use this location to format time string
type JsonpathRender ¶
func (*JsonpathRender) Render ¶
func (r *JsonpathRender) Render(event map[string]interface{}) (value interface{}, err error)
type LiteralValueRender ¶
type LiteralValueRender struct {
// contains filtered or unexported fields
}
func NewLiteralValueRender ¶
func NewLiteralValueRender(template string) *LiteralValueRender
func (*LiteralValueRender) Render ¶
func (r *LiteralValueRender) Render(event map[string]interface{}) (value interface{}, err error)
type MultiLevelValueRender ¶
type MultiLevelValueRender struct {
// contains filtered or unexported fields
}
MultiLevelValueRender is a ValueRender that can render [xxx][yyy][zzz]
func NewMultiLevelValueRender ¶
func NewMultiLevelValueRender(fields []string) *MultiLevelValueRender
NewMultiLevelValueRender create a MultiLevelValueRender
func (*MultiLevelValueRender) Render ¶
func (vr *MultiLevelValueRender) Render(event map[string]interface{}) (value interface{}, err error)
Render implements ValueRender
type OneLevelValueRender ¶
type OneLevelValueRender struct {
// contains filtered or unexported fields
}
func NewOneLevelValueRender ¶
func NewOneLevelValueRender(template string) *OneLevelValueRender
func (*OneLevelValueRender) Render ¶
func (vr *OneLevelValueRender) Render(event map[string]interface{}) (value interface{}, err error)
type TemplateValueRender ¶
type TemplateValueRender struct {
// contains filtered or unexported fields
}
func NewTemplateValueRender ¶
func NewTemplateValueRender(t string) *TemplateValueRender
func (*TemplateValueRender) Render ¶
func (r *TemplateValueRender) Render(event map[string]interface{}) (value interface{}, err error)
Render return "exist" and value. But the returned "exist" is meaningless; the user needs to see if the "value" is nil.
type ValueRender ¶
func GetValueRender ¶
func GetValueRender(template string) ValueRender
GetValueRender return a ValueRender, and return LiteralValueRender if no pattern matched
func GetValueRender2 ¶
func GetValueRender2(template string) ValueRender
GetValueRender2 return a ValueRender, and return OneLevelValueRender("message") if no pattern matched
