public static final FunctionExpressionFactory.ParameterCount ONE_OR_MANY

[1, n] are allowed.

ZERO

public static final FunctionExpressionFactory.ParameterCount ZERO

No parameters are allowed.

ZERO_OR_MANY

Method Detail

values

public static FunctionExpressionFactory.ParameterCount[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (FunctionExpressionFactory.ParameterCount c : FunctionExpressionFactory.ParameterCount.values())
    System.out.println(c);

Returns:

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

valueOf

public static FunctionExpressionFactory.ParameterCount valueOf(String name)

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 name

NullPointerException - if the argument is null
