Method Details

withIncluded

public LabelSetSpec withIncluded(List<Attribute> includedLabels)

Bind this spec to visible child output. Used by outer aggregation before apply().

withExcluded

public LabelSetSpec withExcluded(List<Attribute> excludedLabels)

Bind inherited exclusions and self-resolve against declaredLabels. Used by the innermost aggregate, where no child aggregate output exists yet.

apply

public LabelSetSpec.LabelSet apply()

Finalize the deferred spec into concrete aggregate shape. Result contract: - includedGroupings: actual grouping keys - matchedAttributes: visible output attrs that must survive but are not keys - missingAttributes: BY labels absent from visible output; caller null-fills them - excludedGroupings: concrete dimension exclusions for TimeSeriesWithout

declared

public List<Attribute> declared()

Labels currently known to exist. This is the visible label domain before final apply().

excluded

public List<Attribute> excluded()

Labels known to be excluded by WITHOUT. Empty means the spec is exact.
