OpenJDK 27 · jdk.jfr.internal.query.Field · APIdia, the JavaDoc alternative

Field is the core class of the package.

It contains all the information related to how a field in a query should be grouped, sorted, formatted and aggregated.

Defaults are derived from the metadata available in the event type, for example, numeric fields are right-aligned in the output, but can also be set using query clauses COLUMN and FORMAT.

Settings in {@Configuration } overrides any field setting.
