Golang IntermediateSchema.Labels Examples

Example #1

File: filter.go Project: ubleipzig/span

// Tag takes an intermediate schema and returns a labeled version of that
// schema.
func (t *Tagger) Tag(is finc.IntermediateSchema) finc.IntermediateSchema {
	var tags []string
	for tag, filter := range t.filtermap {
		if filter.Apply(is) {
			tags = append(tags, tag)
		}
	}
	is.Labels = tags
	return is
}
