Deephaven OperationControl
OperationControl.RdAn OperationControl is the return type of Deephaven's op_control function. It is a function that
determines how special values will be handled in the context of an update_by operation.
An OperationControl is intended to be passed directly to a uby function, and should never be instantiated
directly be user code.
If you plan to use the same operation control parameters for multiple uby functions in one or more update_by calls,
consider creating an OperationControl object and reusing it. For example:
opc <- op_control(on_null = 'skip', on_nan = 'poison', big_value_context = 'decimal64')
result <- th$update_by(c(uby_ema_tick(5, c("XEma = X", "YEma = Y"), opc),
uby_emstd_tick(5, c("XEmstd = X", "YEmstd = Y"), opc)),
by="Group")
