Method Detail

get

public RecordList get(Object... keys)

Description copied from class: Lookup

Returns the records that match the supplied composite lookup key.

Contract for subclasses (see also docs/authoring/Lookup.md):

• Called once per source record by LookupTransformer; keep it fast.
• Return an empty RecordList when no match is found. null is also tolerated by LookupTransformer for backward compatibility, but new code should prefer an empty list for clearer semantics.
• Do not mutate the supplied keys; they are owned by the caller.
