Enum Constant Details
-
UNINITIALIZED
Transformer computing transformed = 0.This transformer is used when we initialize the filter, until we get at least one non-zero value to select the proper transformer.
-
PLUS
Transformer computing transformed = g.When this transformer is applied, the roots of the original function are preserved, with the same
increasing/decreasing
status. -
MINUS
Transformer computing transformed = -g.When this transformer is applied, the roots of the original function are preserved, with reversed
increasing/decreasing
status. -
MIN
Transformer computing transformed = min(-Precision.SAFE_MIN
, -g, +g).When this transformer is applied, the transformed function is guaranteed to be always strictly negative (i.e. there are no roots).
-
MAX
Transformer computing transformed = max(+Precision.SAFE_MIN
, -g, +g).When this transformer is applied, the transformed function is guaranteed to be always strictly positive (i.e. there are no roots).

values
Returns an array containing the constants of this enum type, in the order they are declared.- Returns:
- an array containing the constants of this enum type, in the order they are declared
-
valueOf
Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)- Parameters:
name
- the name of the enum constant to be returned.- Returns:
- the enum constant with the specified name
- Throws:
IllegalArgumentException
- if this enum type has no constant with the specified nameNullPointerException
- if the argument is null
