Method Detail

reportInternal

protected void reportInternal(wavefront.report.ReportPoint point)

reject

public void reject(T item)

Description copied from interface: ReportableEntityHandler

Reject the input object as invalid, i.e. rejected based on criteria defined by Wavefront.

Specified by:

reject in interface ReportableEntityHandler<T>

Parameters:

item - object to reject.

reject

public void reject(@Nullable
                   T item,
