Enum Constant Details

Never

public static final Aggregate.ErrorBehaviour Never

Aggregate will never raise an error

MayRaise

public static final Aggregate.ErrorBehaviour MayRaise

May raise an error, even if the input is not unbound (e.g. due to data-type incompatibility)

InputDependent

public static final Aggregate.ErrorBehaviour InputDependent

Produces an error / unbound output if the input argument is unbound (i.e. Variable expr returns an error)

Method Details

values

public static Aggregate.ErrorBehaviour[] values()

Returns an array containing the constants of this enum class, in the order they are declared.

Returns:

an array containing the constants of this enum class, in the order they are declared

valueOf

public static Aggregate.ErrorBehaviour valueOf(String name)

Returns the enum constant of this class with the specified name. The string must match exactly an identifier used to declare an enum constant in this class. (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 class has no constant with the specified name

NullPointerException - if the argument is null
