Examples with TagValue io.opencensus.tags.TagValue used on opensource projects

Example 21 with TagValue

use of io.opencensus.tags.TagValue in project instrumentation-java by census-instrumentation.

the class RecordUtils method getTagValues.

@VisibleForTesting
static List</*@Nullable*/
TagValue> getTagValues(Map<? extends TagKey, TagValueWithMetadata> tags, List<? extends TagKey> columns) {
    List<TagValue> /*@Nullable*/
    tagValues = new ArrayList</*@Nullable*/
    TagValue>(columns.size());
    // Every view aggregates every measure. This is similar to doing a GROUPBY view’s keys.
    for (int i = 0; i < columns.size(); ++i) {
        TagKey tagKey = columns.get(i);
        if (!tags.containsKey(tagKey)) {
            @javax.annotation.Nullable TagValue tagValue = UNKNOWN_TAG_VALUE;
            TagKey[] newKeys = RPC_TAG_MAPPINGS.get(tagKey);
            if (newKeys != null) {
                tagValue = getTagValueForDeprecatedRpcTag(tags, newKeys);
            }
            tagValues.add(tagValue);

            tagValues.add(tags.get(tagKey).getTagValue());
