Method Detail

eval

public abstract boolean eval(Item v1,
                             Item v2)

Evaluates the expression.

Parameters:

v1 - first value

v2 - second value

Returns:

result

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Enum<Comp>

valueOf

public static Comp 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

values

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

Returns:

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