io.opencensus.metrics.data.AttachmentValue

Direct Known Subclasses:

AttachmentValue.AttachmentValueString

public abstract class AttachmentValue
extends Object

The value of Exemplar attachment.

In Stats API we only provide one subclass AttachmentValue.AttachmentValueString. No other subclasses are added because we don't want to introduce dependencies on other libraries, for example Tracing APIs.

Other packages are free to extend this class to hold specific information. As an example, see io.opencensus.contrib.exemplar.util.AttachmentValueSpanContext.
