Check to see if this query matches a set of tags. Common tags or changes to fix invalid characters should be performed prior to checking for a match.

Specified by:

matches in interface Query

Parameters:

tags - Tags to use when checking for a match.

Returns:

True if the query expression matches the tag map.

exactTags in interface Query

Returns:

Tags that are exactly matched as part of the query.

simplify

public Query simplify(Map<String,String> tags)

Description copied from interface: Query

Return a new query that has been simplified by pre-evaluating the conditions for a set of tags that are common to all metrics.

Specified by:

simplify in interface Query
