Enum Constant Detail

DEFAULT

public static final EvaluationType DEFAULT

Use current values when evaluating the expression.

OLD

public static final EvaluationType OLD

Use old/previous values when evaluating the expression.

ESTIMATED

public static final EvaluationType ESTIMATED

Use estimated/future values when evaluating the expression.

Method Detail

values

public static EvaluationType[] 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 (EvaluationType c : EvaluationType.values())
    System.out.println(c);

Returns:

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

valueOf

public static EvaluationType 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

getType

public byte getType()

Returns the corresponding byte value for the evaluation type.
