Protected constructorThe canonical string representations of the allowed values for this column. These are the only values that validate will accept; the server may permit additional representations (e.g. alternate numeric formats).
The allowed values as canonical strings
The fully-qualified protobuf type name of this restriction (e.g.,
"io.deephaven.proto.backplane.grpc.IntegerRangeRestriction").
The restriction type name
A ColumnRestriction that constrains a column to one of a fixed set of allowed values. The allowed values may originate from string, boolean, integer, long, float, or double enum restrictions, but are always normalized to their canonical string representation at construction time (e.g. the integer
10000becomes"10000", the booleantruebecomes"true").validate performs an exact string match against these canonical representations. A value that the server would accept through its own lenient parsing (e.g. `"1e4"` for the integer `10000`, or `"10000.0"` for the integer `10000`) will fail client-side validation even though it may succeed on the server. Callers should treat a `null` result from validate as a definitive pass, but a non-null result as a client-side hint only — the server remains the authoritative source of truth.
