Enum Constant Detail

Bool

public static final LSBBOperator Bool

Boolean decision. Decisional operator with no operand. Decision variable with domain {0,1}.

Int

public static final LSBBOperator Int

Integer decision variable. Decisional operator with two operands min and max. Decision variable with domain [min,max].

Float

public static final LSBBOperator Float

Float decision. Decisional operator with two operands min and max. Decision variable with domain [min,max].

Const

public static final LSBBOperator Const

Constant. Unary operator. Can be equal to any integer. Note that constants 0 or 1 are considered as boolean.

NativeFunction

public static final LSBBOperator NativeFunction

Native function. Native functions are used to retrieve the value of expressions from external functions written with your favorite language. Native functions are created with the dedicated method LSBBModel.createNativeFunction(localsolverblackbox.LSBBNativeFunction).

LSBBNativeFunction

Call

public static final LSBBOperator Call

Call a particular function. The first operand must be a function (like O_NativeFunction). The other operands are passed to the function as arguments.

Method Detail

values

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

Returns:

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

valueOf

public static LSBBOperator valueOf(java.lang.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:

java.lang.IllegalArgumentException - if this enum type has no constant with the specified name

java.lang.NullPointerException - if the argument is null
