generate a group of metrics to iterate over in the form of a set of strings e.g. prefixes . if the metrics to be exported partition into groups identified by a string , subclasses should override this method . otherwise the default should be fine iteration over all metrics . concode_field_sep Log logger concode_elem_sep AtomicBoolean processing concode_elem_sep String prefix concode_elem_sep Date earliestTimestamp concode_elem_sep boolean sendLatest concode_elem_sep boolean ignoreTimestamps concode_elem_sep Date latestTimestamp concode_field_sep void setIgnoreTimestamps concode_elem_sep boolean canExportTimestamp concode_elem_sep Iterable<Metric<?>> next concode_elem_sep void setSendLatest concode_elem_sep void flush concode_elem_sep Metric<?> getPrefixedMetric concode_elem_sep void exportGroups concode_elem_sep void setEarliestTimestamp concode_elem_sep void export concode_elem_sep void write concode_elem_sep void flushQuietly
